It plays a crucial role in regulating growth, metabolism, and overall development throughout life. This hormone stimulates cell reproduction and regeneration, helping the body grow and repair tissues. Growth hormone levels are typically higher during childhood and adolescence to support development but continue to influence health in adulthood. It also helps in managing body composition by promoting muscle growth and reducing fat accumulation. Understanding growth hormone’s function is key to appreciating its importance in maintaining well-being and physical performance over time.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eThe Role of Growth Hormone in Growth and Development\u003c\/h3\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eGrowth hormone significantly affects the physical growth of bones and muscles. It promotes the lengthening of long bones, which is essential during childhood and teenage years. By stimulating the liver to produce insulin-like growth factor 1 (IGF-1), it encourages cell division and tissue growth. This hormone also helps regulate metabolism, influencing how the body uses fats and carbohydrates for energy. Proper growth hormone levels support healthy development, ensuring that children reach their full height potential and maintain strong muscles and bones as they mature.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eHealth Benefits and Anti-Aging Effects of Growth Hormone\u003c\/h3\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eBeyond childhood growth, growth hormone contributes to various health benefits in adults. It supports muscle strength, bone density, and helps reduce body fat, which promotes better physical fitness and metabolic health. Additionally, growth hormone has anti-aging properties by aiding tissue repair and regeneration, improving skin elasticity, and boosting energy levels. While natural levels decline with age, maintaining healthy growth hormone function can enhance quality of life.

The term \"bacteriostatic\" refers to the benzyl alcohol component — a broad-spectrum antimicrobial agent that inhibits bacterial growth and multiplication within the vial, without necessarily killing bacteria outright. This preservative action allows BAC water to remain safely usable across multiple withdrawals over an extended period — a critical property that distinguishes it from standard sterile water for injection, which is intended for single-use only and carries no microbial protection after the vial seal is first broken.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eBAC water is the standard reconstitution vehicle for a wide range of lyophilised research peptides, proteins, and biological compounds — including human growth hormone (HGH), GHRFs, GHRPs, and most synthetic research peptides. It is used wherever a multi-dose reconstitution protocol is required, and where peptide or protein stability across multiple draw-down events must be maintained without microbial contamination risk.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eOur bacteriostatic water is manufactured to research grade: sterile, pyrogen-free, and packaged in sealed multi-dose vials with halogenated butyl stoppers compatible with standard research syringes and needle gauges.\u003c\/p\u003e\n\u003chr class=\"border-border-200 border-t-0.5 my-3 mx-1.5\"\u003e\n\u003ch3 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003eWhy BAC Water Matters for Peptide Research\u003c\/h3\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe choice of reconstitution vehicle is one of the most practically consequential decisions in peptide research — and one that is frequently underestimated. Using an inappropriate reconstitution solution can compromise peptide stability, alter solubility, affect experimental reproducibility, and — in the case of multi-dose vials — introduce microbial contamination that invalidates results and degrades the compound.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eBacteriostatic water addresses these concerns by providing a chemically inert, pH-appropriate, sterile environment with sustained antimicrobial protection across repeated vial access events. For researchers working with lyophilised peptides that require reconstitution before use — including every compound in our research catalogue — BAC water is the most broadly appropriate and widely used reconstitution vehicle in the scientific literature.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eCompatibility with our catalogue:\u003c\/strong\u003e BAC water is the recommended reconstitution vehicle for HGH (somatotropin), tesamorelin, BPC-157, TB-500, MOTS-c, Selank, and the majority of other lyophilised research peptides. GHK-Cu is optimally reconstituted in sterile water or PBS, and 5-Amino-1MQ may require DMSO for certain protocols — but for the majority of peptide reconstitution applications, BAC water is the first-choice solution.\u003c\/p\u003e\n\u003chr class=\"border-border-200 border-t-0.5 my-3 mx-1.5\"\u003e\n\u003ch3 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003eComposition \u0026amp; Technical Specifications\u003c\/h3\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eWhy 0.9% benzyl alcohol?\u003c\/strong\u003e Benzyl alcohol has been used as an antimicrobial preservative in injectable preparations since the 1920s. At 0.9% concentration, it provides effective bacteriostatic activity against a broad spectrum of gram-positive and gram-negative bacteria — the most likely contaminants in a multi-access vial environment — while remaining chemically compatible with the widest range of peptides, proteins, and hormones used in research. Higher benzyl alcohol concentrations can begin to affect protein folding and stability; 0.9% represents the established standard for balancing preservation efficacy with compound compatibility.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eWhy not sterile water for injection?\u003c\/strong\u003e Standard sterile water for injection (SWFI) contains no preservative and is intended for single-use only. Once the seal is broken and the vial accessed, SWFI provides no protection against bacterial contamination from subsequent needle insertions. For researchers who routinely draw multiple aliquots from a single reconstituted vial over days or weeks — as is standard practice with peptide research compounds — SWFI is inappropriate and significantly increases the risk of microbial contamination that will degrade the compound and compromise experimental results.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eWhy not saline or PBS?\u003c\/strong\u003e Normal saline (0.9% sodium chloride) and phosphate-buffered saline (PBS) are appropriate for some peptide reconstitution applications but carry important caveats. Saline can reduce the solubility of certain peptides and proteins and provides no preservative action in multi-dose vials. PBS introduces phosphate and salt ions that can interact with some peptides and alter their behaviour in downstream assays. For most lyophilised research peptide applications, BAC water provides a cleaner, more universally compatible, and more practically convenient reconstitution vehicle.\u003c\/p\u003e\n\u003chr class=\"border-border-200 border-t-0.5 my-3 mx-1.5\"\u003e\n\u003ch3 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003eBAC Water and Peptide Stability\u003c\/h3\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eProper reconstitution practice is as important as purity when it comes to preserving the integrity and research utility of lyophilised peptides. The following principles apply to reconstitution with BAC water across the research peptide catalogue:\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eTechnique:\u003c\/strong\u003e Always inject BAC water slowly against the side of the vial — never directly onto the lyophilised powder, which can mechanically disrupt peptide structure. Swirl gently until dissolved; do not shake or vortex.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eTemperature:\u003c\/strong\u003e Allow the lyophilised vial to reach room temperature before reconstitution.

The benzyl alcohol preservative protects against microbial growth but does not prevent peptide degradation from heat or light exposure. Reconstituted solutions should be used within the timeframes recommended for each specific compound — typically 28 days for HGH and tesamorelin, and up to 30 days for shorter synthetic peptides, though this varies by compound.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eFreeze-thaw:\u003c\/strong\u003e Reconstituted peptide solutions in BAC water should not be re-frozen unless the specific compound's data sheet indicates this is acceptable.

Endogenous GHRH is a 44-amino acid hypothalamic peptide that triggers GH release from anterior pituitary somatotrophs. However, the native molecule is rapidly degraded in circulation — primarily by the serum enzyme dipeptidyl peptidase-4 (DPP-4), which cleaves at the Tyr-Ala bond at the N-terminus — resulting in a biological half-life of just two to seven minutes. This extreme brevity makes native GHRH largely impractical as a sustained research tool.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe first step toward a solution was GRF (1-29), also known as sermorelin — a truncated 29-amino acid fragment of GHRH that retains full receptor binding and biological activity, as the first 29 residues contain the complete pharmacophore for GHRH receptor activation. Modified GRF (1-29) — CJC-1295 No DAC — takes this a step further through four targeted amino acid substitutions at positions 2, 8, 15, and 27 of the GRF (1-29) sequence:\u003c\/p\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003ePosition 2:\u003c\/strong\u003e L-alanine → D-alanine — provides primary protection against DPP-4 enzymatic cleavage at the N-terminus\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003ePosition 8:\u003c\/strong\u003e Asparagine → Glutamine — reduces oxidative instability during manufacture and storage\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003ePosition 15:\u003c\/strong\u003e Glycine → Alanine — enhances structural rigidity and reduces conformational susceptibility to peptidase activity\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003ePosition 27:\u003c\/strong\u003e Methionine → Leucine — eliminates a methionine oxidation site, significantly improving chemical stability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThese four substitutions collectively elevate the half-life of Modified GRF (1-29) from the two-to-seven minute range of native GHRH to approximately 30 minutes — long enough to produce a meaningful GH secretory pulse while remaining short enough to preserve the physiologically important pulsatile pattern of GH release and maintain hypothalamic-pituitary feedback regulation.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eA critical nomenclature note for researchers:\u003c\/strong\u003e The term \"CJC-1295\" in the scientific literature formally refers to CJC-1295 DAC — the albumin-binding, long-acting form of the compound developed by ConjuChem Biotechnologies, which carries an additional Drug Affinity Complex (DAC) modification enabling covalent binding to serum albumin and producing a half-life of approximately six to eight days. \"CJC-1295 No DAC\" or \"CJC-1295 without DAC\" is a widely used commercial synonym for Modified GRF (1-29) — and while this nomenclature is ubiquitous in the research peptide community, it is important for researchers to recognise that these are pharmacologically distinct compounds with substantially different pharmacokinetic profiles and experimental implications.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eOur CJC-1295 No DAC is synthesised under strict quality-controlled manufacturing conditions and verified to a purity of greater than 99% by HPLC and Mass Spectrometry.

Its primary scientific value lies in its ability to amplify physiological pulsatile GH secretion — making it a valuable tool for researchers seeking to study the effects of GHRH receptor activation and downstream GH\/IGF-1 signalling under conditions that preserve normal hormonal feedback architecture.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eGHRH Receptor Activation \u0026amp; Pulsatile GH Secretion\u003c\/strong\u003e CJC-1295 No DAC binds with high affinity to the GHRH receptor (GHRH-R) — a class B G protein-coupled receptor expressed on somatotroph cells of the anterior pituitary. Receptor binding activates the adenylate cyclase–cAMP–PKA intracellular signalling cascade, stimulating both acute GH secretion and GH gene transcription. Because the compound's half-life of approximately 30 minutes is short relative to the natural inter-pulse interval of GH secretion (typically 90–180 minutes), CJC-1295 No DAC produces discrete GH pulses that mimic the physiological secretory pattern rather than creating sustained GH elevation. This pulsatile character is considered experimentally important: the liver and peripheral tissues respond differently to pulsatile versus continuous GH exposure, and several of GH's anabolic and lipolytic effects are specifically dependent on the pulse pattern rather than mean concentration. Researchers studying the distinction between physiological and pharmacological GH signalling will find this a meaningful design consideration in protocol selection.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eCJC-1295 No DAC vs. Tesamorelin: Pharmacokinetic Research Design Considerations\u003c\/strong\u003e Both CJC-1295 No DAC and tesamorelin are stabilised GHRH analogues that act at the GHRH receptor to stimulate pulsatile GH secretion — and they are frequently compared by researchers selecting between them. The key differences are structural and pharmacokinetic. Tesamorelin is a 44-amino acid analogue of full-length GHRH, stabilised by an N-terminal trans-3-hexenoic acid modification and carrying a half-life of approximately 30–40 minutes. CJC-1295 No DAC is a tetrasubstituted 29-amino acid fragment with a half-life of approximately 30 minutes. Both produce physiologically comparable pulsatile GH release patterns and preserve feedback regulation. Tesamorelin carries the more extensive clinical validation dataset — including FDA approval and large Phase III trial data — while CJC-1295 No DAC is more widely used as a general-purpose GHRH-axis research tool given its broader availability and established use in the preclinical literature. Both are available in our catalogue, allowing researchers to select the most appropriate compound for their experimental model. Tesamorelin is generally preferred when clinical translatability or regulatory alignment is a research priority; CJC-1295 No DAC is appropriate for preclinical mechanistic studies of the GHRH-GH-IGF-1 axis.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eCJC-1295 No DAC vs. CJC-1295 DAC: Key Research Design Distinction\u003c\/strong\u003e The choice between CJC-1295 No DAC and CJC-1295 DAC is one of the most consequential protocol decisions in GHRH-axis research, yet it is frequently confused — including, as noted above, in some published scientific literature. CJC-1295 No DAC produces a ~30 minute half-life with discrete pulsatile GH secretion. CJC-1295 DAC — through its albumin-binding Drug Affinity Complex — achieves a half-life of approximately six to eight days, producing sustained GH elevation across a prolonged period and blunting the natural pulse architecture. These are fundamentally different experimental conditions. Researchers studying physiological GH pulsatility, natural feedback dynamics, or acute GHRH receptor pharmacology should use CJC-1295 No DAC. Researchers studying the effects of sustained GH elevation, or requiring a long-acting dosing interval, should use CJC-1295 DAC. Using the wrong compound for the experimental question is a meaningful source of variability and potential error in GH-axis research design.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eGH\/IGF-1 Axis \u0026amp; Anabolic Signalling Research\u003c\/strong\u003e As a GHRH receptor agonist, CJC-1295 No DAC elevates GH secretion, which in turn drives hepatic and peripheral IGF-1 production. IGF-1 — acting through the IGF-1 receptor and downstream PI3K–Akt–mTOR and MAPK signalling cascades — mediates the principal anabolic, growth-promoting, and tissue-remodelling effects of the GH\/IGF-1 axis. Preclinical research has examined CJC-1295 No DAC (and related GHRH analogues) in models of skeletal muscle protein synthesis, lean mass accretion, adipose tissue lipolysis, bone mineral density, and collagen synthesis — with IGF-1 elevation identified as the primary mediator of these downstream effects.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eMetabolic \u0026amp; Body Composition Research\u003c\/strong\u003e Growth hormone directly stimulates lipolysis in adipose tissue via hormone-sensitive lipase activation, and indirectly promotes lean mass accrual through IGF-1-mediated protein synthesis and nitrogen retention. CJC-1295 No DAC's amplification of pulsatile GH secretion has made it a useful tool in preclinical studies examining these metabolic effects, including models of age-related body composition change and GH deficiency states. The compound's preservation of pulsatile GH dynamics is particularly relevant in this context, as the lipolytic effects of GH are known to be pulse-amplitude-dependent.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eSomatopause \u0026amp; Ageing Research\u003c\/strong\u003e The progressive decline in GHRH output and GH pulsatility with age — somatopause — produces a characteristic pattern of metabolic deterioration including increased visceral adiposity, reduced lean mass, and impaired tissue repair capacity. CJC-1295 No DAC, as a tool for restoring GHRH receptor stimulation and augmenting pulsatile GH output, has been studied in preclinical models of somatopause-associated metabolic change. Its mechanism of action — upstream stimulation of pituitary GH secretion rather than exogenous GH replacement — preserves the regulatory architecture of the hypothalamic-pituitary axis, making it a pharmacologically distinct tool from direct rhGH administration in ageing research models.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eCombination Research with GHRPs\u003c\/strong\u003e CJC-1295 No DAC is frequently studied in combination with growth hormone-releasing peptides (GHRPs) — including ipamorelin, GHRP-2, and GHRP-6 — in preclinical research protocols. GHRPs act at the ghrelin receptor (GHSR-1a) to amplify GH secretion through a distinct and mechanistically complementary pathway from GHRH receptor activation. The combination of a GHRH analogue (CJC-1295 No DAC) with a GHRP is known to produce synergistic GH release substantially exceeding the effect of either compound alone — a finding consistent with the known synergistic relationship between the GHRH and ghrelin pathways in regulating pituitary GH secretion. This combination approach has become one of the most common experimental paradigms in preclinical GH-axis research and is an important consideration for researchers designing multi-peptide studies.\u003c\/p\u003e\n\u003chr class=\"border-border-200 border-t-0.5 my-3 mx-1.5\"\u003e\n\u003ch3 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003eProduct Specifications\u003c\/h3\u003e\n\u003cdiv class=\"overflow-x-auto w-full px-2 mb-6\"\u003e\n\u003ctable class=\"min-w-full border-collapse text-sm leading-[1.7] whitespace-normal\"\u003e\n\u003cthead class=\"text-left\"\u003e\n\u003ctr\u003e\n\u003cth scope=\"col\" class=\"text-text-100 border-b-0.5 border-border-300\/60 py-2 pr-4 align-top font-bold\"\u003eSpecification\u003c\/th\u003e\n\u003cth scope=\"col\" class=\"text-text-100 border-b-0.5 border-border-300\/60 py-2 pr-4 align-top font-bold\"\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003ePeptide\u003c\/td\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003eCJC-1295 No DAC (Modified GRF 1-29)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003eAlso Known As\u003c\/td\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003eMod GRF 1-29, Modified GRF (1-29), CJC-1295 without DAC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003eSequence\u003c\/td\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003eTyr-D-Ala-Asp-Ala-Ile-Phe-Thr-Gln-Ser-Tyr-Arg-Lys-Val-Leu-Ala-Gln-Leu-Ser-Ala-Arg-Lys-Leu-Leu-Gln-Asp-Ile-Leu-Ser-Arg-NH₂\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003eKey Substitutions\u003c\/td\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003eD-Ala² \/ Gln⁸ \/ Ala¹⁵ \/ Leu²⁷\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003eMolecular Formula\u003c\/td\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003eC₁₅₂H₂₅₂N₄₄O₄₂\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003eMolecular Weight\u003c\/td\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003e3367.97 g\/mol\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003ePurity\u003c\/td\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003e\u0026gt;99% (HPLC \u0026amp;

It was derived from GHRP-1 through a systematic chemistry programme that identified active analogues lacking the central Ala-Trp dipeptide of the parent compound, ultimately yielding ipamorelin as the most pharmacologically refined member of its series.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eIpamorelin's significance in the research peptide landscape rests on a single, defining characteristic: it is the first growth hormone-releasing peptide receptor agonist to demonstrate a selectivity for GH release comparable to that of endogenous GHRH itself. All earlier GHRPs — including GHRP-2 and GHRP-6 — stimulated GH release but also produced dose-dependent elevations in ACTH and cortisol through activation of broader stress-response signalling pathways. Ipamorelin does not. In the foundational Novo Nordisk pharmacology studies, ipamorelin failed to elevate ACTH or cortisol at doses more than 200-fold above its ED50 for GH release — a specificity profile that had not previously been achieved with any GHRP receptor agonist and that fundamentally changed the landscape of GH secretagogue research.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eStructurally, ipamorelin incorporates three key non-natural amino acid features that underpin its selectivity and metabolic stability. The α-aminoisobutyric acid (Aib) residue at position 1 confers resistance to N-terminal peptidase cleavage. The D-2-naphthylalanine (D-2-Nal) at position 3 — a bulky, non-natural amino acid — provides critical receptor binding contributions and contributes to selectivity. The D-phenylalanine (D-Phe) at position 4 further stabilises the receptor-bound conformation. Together, these modifications produce a compound with substantially lower systemic plasma clearance than GHRP-6 — approximately five-fold lower — and moderate resistance to metabolic degradation, resulting in a more sustained and reproducible GH secretory response.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eIpamorelin stimulates pulsatile GH secretion from anterior pituitary somatotrophs by acting at the ghrelin receptor (GHS-R1a) — a distinct and mechanistically complementary pathway to the GHRH receptor pathway through which CJC-1295 No DAC and tesamorelin operate. This mechanistic distinction is the basis of the well-established synergistic relationship between ipamorelin and GHRH analogues in GH secretion research.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eOur ipamorelin is synthesised under rigorous quality-controlled manufacturing conditions, verified to a purity of greater than 99% by HPLC and Mass Spectrometry, and supplied as a lyophilised (freeze-dried) powder for maximum stability.\u003c\/p\u003e\n\u003chr class=\"border-border-200 border-t-0.5 my-3 mx-1.5\"\u003e\n\u003ch3 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003eResearch Background \u0026amp; Scientific Interest\u003c\/h3\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eIpamorelin has accumulated a rich and diverse body of preclinical research since its characterisation in 1998, spanning GH secretagogue pharmacology, metabolic biology, bone mineral density, gastrointestinal motility, and body composition research. Its defining selectivity profile has made it the reference compound of choice for ghrelin receptor agonism research where hormonal specificity is a priority experimental requirement.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eGHS-R1a Receptor Pharmacology \u0026amp; Selectivity\u003c\/strong\u003e Ipamorelin's receptor pharmacology was comprehensively characterised in the original Novo Nordisk studies. In vitro, ipamorelin released GH from primary rat pituitary cells with a potency and efficacy closely comparable to GHRP-6 — achieving an EC50 of 1.3 ± 0.4 nmol\/L and an Emax of 85 ± 5% relative to GHRP-6's 100% reference maximum. In vivo, in conscious swine — a model with GH axis pharmacology closely reflective of human GH secretion — ipamorelin produced an ED50 of 2.3 ± 0.03 nmol\/kg and an Emax of 65 ± 0.2 ng GH\/mL plasma, comparable to GHRP-6 (ED50 3.9 ± 1.4 nmol\/kg, Emax 74 ± 7 ng\/mL) but with substantially superior selectivity. Critically, pharmacological profiling using both GHRP receptor antagonists and GHRH antagonists confirmed that ipamorelin stimulates GH release exclusively via the GHRP\/ghrelin receptor pathway — the same receptor used by GHRP-2 and GHRP-6 — rather than through the GHRH receptor. This orthogonal mechanism is the mechanistic basis of the synergistic GH release observed when ipamorelin is combined with GHRH analogues such as CJC-1295 No DAC.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eHormonal Selectivity: No ACTH, Cortisol, Prolactin or Gonadotropin Elevation\u003c\/strong\u003e The most scientifically significant finding in the ipamorelin pharmacology literature is its hormonal selectivity profile. In the definitive swine selectivity study, none of the GH secretagogues tested — including ipamorelin, GHRP-6, and GHRP-2 — affected FSH, LH, prolactin, or TSH levels. However, administration of both GHRP-6 and GHRP-2 produced significant elevations in plasma ACTH and cortisol. Ipamorelin produced no significant elevation in ACTH or cortisol at any dose tested — including doses exceeding 200-fold the GH-releasing ED50. This was described by the original authors as \"very surprising\" and represented a categorically different selectivity profile from all previously characterised GHRP receptor agonists. The practical research implication is substantial: studies using ipamorelin to investigate GH\/IGF-1 axis effects are not confounded by concurrent activation of the hypothalamic-pituitary-adrenal (HPA) axis — a major experimental advantage over GHRP-2 and GHRP-6 in any protocol where cortisol or ACTH are outcome variables, or where HPA axis activation would represent an uncontrolled experimental variable.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003ePulsatile GH Secretion \u0026amp; IGF-1 Axis Research\u003c\/strong\u003e Like CJC-1295 No DAC, ipamorelin stimulates pulsatile rather than continuous GH secretion. Its half-life of approximately two hours in rodent models — longer than GHRP-6 due to its approximately five-fold lower systemic plasma clearance — produces GH pulses of meaningful duration while preserving the inter-pulse intervals that allow natural somatostatin feedback to operate. Elevated GH secretion drives downstream IGF-1 production, mediated primarily through hepatic GH receptor signalling, and the GH\/IGF-1 axis effects of ipamorelin — including anabolic signalling in skeletal muscle, lipolytic activity in adipose tissue, and effects on bone metabolism — have been studied in multiple preclinical models.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eBone Mineral Density Research\u003c\/strong\u003e Ipamorelin has been studied in models of bone metabolism, with preclinical data demonstrating increases in bone mineral content (BMC) in treated female rats as measured by dual-energy X-ray absorptiometry (DXA) in vivo. Comparative studies examining ipamorelin and GHRP-6 both demonstrated BMC increases, consistent with the known role of the GH\/IGF-1 axis in bone formation, periosteal expansion, and endochondral ossification. These findings have positioned ipamorelin as a tool of interest in preclinical osteoporosis research and models of GH deficiency-associated bone loss.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eGastrointestinal Motility Research\u003c\/strong\u003e The GHS-R1a receptor is expressed not only in the pituitary and hypothalamus but throughout the gastrointestinal tract — reflecting the physiological role of ghrelin as a gut-derived hormone regulating gastric motility and appetite. Ipamorelin has been studied in preclinical models of gastrointestinal dysfunction, including postoperative ileus (POI) — a clinically important condition characterised by delayed gastric emptying following abdominal surgery. Studies by Greenwood-Van Meerveld and colleagues using rodent POI models demonstrated that ipamorelin produced dose-dependent improvements in gastric emptying and reversal of POI-induced delayed gastrointestinal transit, with effects mediated through GHS-R1a expressed in gastrointestinal smooth muscle and enteric nervous system tissue. These findings have expanded ipamorelin's research relevance into gastrointestinal biology beyond its primary GH secretagogue profile.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eBody Composition \u0026amp; Metabolic Research\u003c\/strong\u003e The downstream metabolic effects of ipamorelin-stimulated GH\/IGF-1 axis activation — including GH-mediated lipolysis in adipose tissue, IGF-1-mediated skeletal muscle protein synthesis, and nitrogen retention — have made ipamorelin a useful tool in preclinical body composition research. Studies have examined ipamorelin in models of lean mass accretion, visceral fat reduction, and metabolic syndrome, with findings consistent with the broader GH\/IGF-1 axis literature. Its hormonal selectivity — specifically the absence of cortisol elevation — is a meaningful research advantage in these models, as elevated cortisol has well-documented catabolic effects on muscle tissue that would otherwise confound body composition outcomes.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eCombination Research: Ipamorelin + CJC-1295 No DAC (GHRH + GHRP Synergy)\u003c\/strong\u003e One of the most important and widely replicated findings in GH secretagogue research is the synergistic relationship between GHRH-axis peptides and GHRP-class peptides in stimulating GH release. When a GHRH analogue (such as CJC-1295 No DAC) and a GHRP (such as ipamorelin) are administered together, the combined GH release substantially exceeds the sum of the individual responses — a finding consistent with the well-established physiological synergism between the hypothalamic GHRH and ghrelin systems. This occurs because the two compounds act through distinct and mechanistically independent receptors (GHRH-R and GHS-R1a respectively), and their downstream signalling cascades converge synergistically at the level of pituitary somatotroph GH secretion. This combination paradigm — CJC-1295 No DAC paired with ipamorelin — has become one of the most commonly used experimental protocols in preclinical GH-axis research, and both compounds are available in our catalogue to support this research design.\u003c\/p\u003e\n\u003chr class=\"border-border-200 border-t-0.5 my-3 mx-1.5\"\u003e\n\u003ch3 class=\"text-text-100 mt-2 -mb-1 text-base

While native GHRH is pharmacologically active, it is rapidly degraded in vivo by the serum enzyme dipeptidyl peptidase-4 (DPP-4) — which cleaves at the Tyr-Ala bond at the N-terminus — resulting in a biological half-life of only a few minutes and rendering it largely unsuitable as a sustained research tool.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eTesamorelin addresses this limitation through a precise structural modification: conjugation of a trans-3-hexenoic acid moiety to the N-terminal tyrosine residue. This hydrophobic modification sterically protects the DPP-4 cleavage site, producing a compound with significantly enhanced metabolic stability while retaining full agonist activity at the GHRH receptor. The result is a peptide that reproduces the physiological pulsatile pattern of GH secretion — preserving the natural hypothalamic-pituitary feedback architecture — rather than delivering continuous, supraphysiological GH exposure as exogenous rhGH administration does. This key distinction has major implications for research design and for the safety and hormonal specificity profile of tesamorelin relative to direct GH administration.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eOur tesamorelin is synthesised under strict quality-controlled manufacturing conditions, verified to a purity of greater than 99% by High-Performance Liquid Chromatography (HPLC) and Mass Spectrometry (MS), and supplied as a lyophilised (freeze-dried) powder for optimal stability.\u003c\/p\u003e\n\u003chr class=\"border-border-200 border-t-0.5 my-3 mx-1.5\"\u003e\n\u003ch3 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003eResearch Background \u0026amp; Clinical Data\u003c\/h3\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eTesamorelin carries one of the most extensive and rigorously validated clinical research profiles of any peptide available for laboratory study. It has been evaluated in large-scale, randomised, double-blind, placebo-controlled Phase III trials involving over 800 participants, with findings published in leading peer-reviewed journals. This level of clinical evidence is exceptional within the research peptide landscape and makes tesamorelin a uniquely robust reference compound for the GH\/IGF-1 axis.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eMechanism: GHRH Receptor Activation \u0026amp; Pulsatile GH Secretion\u003c\/strong\u003e Tesamorelin binds with high affinity to the growth hormone-releasing hormone receptor (GHRH-R) — a G-protein-coupled receptor expressed predominantly on somatotroph cells of the anterior pituitary. Receptor binding activates the adenylate cyclase–cAMP–PKA intracellular signalling cascade, promoting both acute GH release and longer-term GH gene transcription. Critically, this mechanism preserves the natural pulsatile pattern of GH secretion and maintains hypothalamic-pituitary IGF-1 feedback inhibition — meaning GH release remains physiologically regulated rather than driven to sustained supraphysiological levels. Downstream, elevated GH stimulates hepatic and peripheral production of IGF-1 and IGF binding protein-3 (IGFBP-3), which mediate the compound's anabolic, lipolytic, and tissue-remodelling effects at target tissues.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003ePulsatile GH Augmentation — Clinical Study in Healthy Males\u003c\/strong\u003e A landmark mechanistic study published in the Journal of Clinical Endocrinology \u0026amp; Metabolism examined the effects of tesamorelin at 2 mg daily for two weeks in 13 healthy males. Tesamorelin significantly increased mean overnight GH, average GH peak area, and basal GH secretion. IGF-1 increased by 181 ± 22 μg\/litre (P \u0026lt; 0.0001), while neither fasting glucose nor insulin-stimulated glucose uptake was significantly affected — an important finding demonstrating that tesamorelin's GH stimulation can substantially elevate IGF-1 without impairing peripheral insulin sensitivity, a key differentiator from direct exogenous rhGH administration.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003ePhase III Clinical Trials: HIV-Associated Lipodystrophy (LIPO-010 \u0026amp; CTR-1011)\u003c\/strong\u003e The pivotal Phase III evidence base for tesamorelin comprises two large, multicentre, randomised, double-blind, placebo-controlled trials — LIPO-010 (n=412) and CTR-1011 (n=404) — enrolling a combined total of 816 HIV-infected patients with excess visceral adiposity associated with antiretroviral therapy. Across both trials, tesamorelin demonstrated consistent reductions in visceral adipose tissue (VAT) of approximately 15–20%, accompanied by improvements in triglycerides, waist circumference, and patient-reported body image outcomes. These results were robust, reproducible across both trials, and formed the basis of the compound's FDA approval in 2010 as the first and only medication specifically indicated for reducing excess abdominal fat in HIV-infected patients with lipodystrophy. An important finding from these trials was that tesamorelin significantly reduced visceral adipose tissue without adversely affecting subcutaneous fat or inducing insulin resistance — a clinically meaningful distinction from direct GH therapy.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eNAFLD \u0026amp; Liver Fat Research — The Lancet HIV\u003c\/strong\u003e Beyond visceral fat reduction, tesamorelin has been studied in models of metabolic dysfunction-associated liver disease.

Given the well-established role of the GH\/IGF-1 axis in hippocampal neurogenesis, synaptic plasticity, and neuroprotection — and the progressive decline of GH secretion with age — tesamorelin has been investigated as a research tool for examining GH-mediated cognitive effects. Studies have explored tesamorelin's influence on verbal memory, executive function, and brain amyloid-beta metabolism in older adults, with findings suggesting a potential role for the GH\/IGF-1 axis in age-related cognitive trajectories that merits continued investigation.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eMetabolic Syndrome \u0026amp; Insulin Resistance Research\u003c\/strong\u003e Beyond the HIV-lipodystrophy indication, researchers have studied tesamorelin in broader models of visceral obesity and metabolic syndrome. Tesamorelin's stimulation of pulsatile GH release is thought to preferentially target visceral adipose tissue, suppress hepatic lipogenesis, and improve body-composition biomarkers. Its selectivity for visceral over subcutaneous fat — a pattern consistent with the physiological role of pulsatile GH in fat distribution — makes tesamorelin a valuable tool for researchers seeking to dissect the specific metabolic consequences of visceral adiposity and GH axis dysregulation.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eAgeing \u0026amp; Somatopause Research\u003c\/strong\u003e The progressive decline in GH secretion with age — somatopause — is associated with increased visceral adiposity, reduced lean mass, impaired bone density, and deteriorating metabolic parameters.

Direct rhGH administration delivers continuous, non-pulsatile GH exposure that can suppress endogenous GH secretion via negative feedback and frequently drives IGF-1 to supraphysiological levels — increasing the risk of insulin resistance and other GH excess effects. Tesamorelin, by contrast, stimulates the pituitary to release GH in the natural pulsatile pattern, maintains hypothalamic-pituitary feedback integrity, and produces more physiological IGF-1 elevation. This distinction is experimentally important: researchers studying the consequences of physiological versus supraphysiological GH axis activity, or seeking to model GH restoration without disrupting endocrine homeostasis, will find tesamorelin and rhGH produce meaningfully different experimental conditions that must be accounted for in protocol design.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eBoth tesamorelin and rhGH are available in our catalogue, allowing researchers to select the most appropriate tool for their specific experimental model.\u003c\/p\u003e\n\u003chr class=\"border-border-200 border-t-0.5 my-3 mx-1.5\"\u003e\n\u003ch3 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003eProduct Specifications\u003c\/h3\u003e\n\u003cdiv class=\"overflow-x-auto w-full px-2 mb-6\"\u003e\n\u003ctable class=\"min-w-full border-collapse text-sm leading-[1.7] whitespace-normal\"\u003e\n\u003cthead class=\"text-left\"\u003e\n\u003ctr\u003e\n\u003cth scope=\"col\" class=\"text-text-100 border-b-0.5 border-border-300\/60 py-2 pr-4 align-top font-bold\"\u003eSpecification\u003c\/th\u003e\n\u003cth scope=\"col\" class=\"text-text-100 border-b-0.5 border-border-300\/60 py-2 pr-4 align-top font-bold\"\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003ePeptide\u003c\/td\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003eTesamorelin (TH9507)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003eClassification\u003c\/td\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003eStabilised GHRH analogue — 44-amino acid polypeptide\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003eN-terminal Modification\u003c\/td\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003eTrans-3-hexenoic acid (DPP-4 protection)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003eMolecular Formula\u003c\/td\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003eC₂₂₁H₃₆₆N₇₂O₆₇S\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003eMolecular Weight\u003c\/td\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003e5135.77 g\/mol\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003ePurity\u003c\/td\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003e\u0026gt;99% (HPLC \u0026amp;

It is one of the most structurally and functionally characterised hormones in human biology, and one of the longest-studied peptide hormones in the scientific literature — with research dating back to the 1950s. Its characteristic four-helix bundle structure is essential for binding to the growth hormone receptor (GHR), and this interaction underlies the full spectrum of its biological activity.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eHGH production is tightly regulated by several complex feedback mechanisms in response to stress, exercise, nutrition, sleep, and growth hormone. The primary regulatory factors are growth hormone-releasing hormone (GHRH), produced in the hypothalamus; somatostatin, produced in various tissues throughout the body; and ghrelin, produced in the gastrointestinal tract. The net result of these interlocking regulatory signals is a pulsatile release pattern — with the largest secretory pulses occurring during deep sleep — that produces circulating HGH levels which peak during adolescence and decline progressively with age thereafter.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe recombinant human growth hormone (rhGH) supplied here is produced via recombinant DNA technology, yielding a molecule that is structurally identical to endogenous pituitary-derived somatotropin.

Its central role in growth, metabolism, and tissue homeostasis makes it a foundational reference compound for researchers across a wide range of disciplines.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eMechanism of Action: Direct \u0026amp; Indirect Pathways\u003c\/strong\u003e HGH has two mechanisms of action: direct and indirect. The direct effects of HGH on the body occur through its binding to target cells, stimulating a response. The indirect effects occur primarily through insulin-like growth factor-1 (IGF-1), which hepatocytes secrete in response to elevated HGH binding to surface receptors. Once activated, the Janus-activated tyrosine kinases (JAKs) 1 and 2 bind to the latent cytoplasmic transcription factors STAT1, STAT3, and STAT5, and transport them into the nucleus, inducing increased gene transcription and metabolism to produce IGF-1 for release into the circulation. IGF-1 then mediates many of HGH's anabolic and growth-promoting effects at peripheral tissues. Researchers therefore study HGH and IGF-1 as an integrated axis rather than as independent compounds.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eGrowth, Cell Proliferation \u0026amp; Tissue Development\u003c\/strong\u003e HGH stimulates growth, cell reproduction, and cell regeneration in humans and other animals, and also stimulates production of IGF-1 and increases the concentration of glucose and free fatty acids. In the context of preclinical research, this broad anabolic and mitogenic activity makes HGH a central reference compound in studies examining skeletal growth, organ development, chondrocyte and osteoblast biology, and the regulation of cell cycle progression. Its role in cartilage and long bone development via IGF-1-mediated growth plate stimulation remains one of the most studied areas of growth hormone biology.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eMetabolic Research: Lipolysis, Glucose Homeostasis \u0026amp; Body Composition\u003c\/strong\u003e HGH exerts direct metabolic effects that are distinct from — and at times opposing to — its IGF-1-mediated growth effects. In preclinical and clinical research, HGH has been studied extensively for its lipolytic activity: it directly stimulates hormone-sensitive lipase in adipose tissue, promoting the mobilisation of free fatty acids as an energy substrate. Simultaneously, HGH exerts anti-insulin effects by reducing peripheral glucose uptake and increasing hepatic glucose output — effects that have made the GH–IGF-1 axis a central subject in diabetes research, insulin sensitivity modelling, and metabolic syndrome studies. Researchers use rhGH as a reference compound to investigate the interaction between growth factor signalling and insulin signalling pathways, as well as the downstream effects of GH excess and deficiency states on body composition, fat distribution, and lipid metabolism.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eMusculoskeletal \u0026amp; Anabolic Research\u003c\/strong\u003e The role of HGH in skeletal muscle biology has been a subject of sustained research interest. Preclinical studies have investigated HGH's influence on satellite cell activation, myofibrillar protein synthesis, muscle hypertrophy, and recovery from muscle injury — effects largely mediated through the GH receptor and downstream IGF-1 signalling in muscle tissue. HGH is known to help improve and increase muscle mass through a process known as hypertrophy, and also boosts protein synthesis in the body. Research has also examined HGH's effects on nitrogen retention, amino acid transport, and the balance between protein synthesis and degradation in skeletal muscle — making it an important reference compound in studies examining sarcopenia, cachexia, and muscle wasting conditions.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eHGH's influence on bone mineral density and calcium metabolism has similarly attracted substantial research attention. It is also known to help improve calcium retention in cells, which leads to an increase in bone strength. Preclinical and translational research has investigated these effects in models of osteoporosis, fracture healing, and skeletal remodelling, with IGF-1 identified as a key mediator of HGH's osteoanabolic activity.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eImmune System Research\u003c\/strong\u003e Another well-known function of HGH is the way it acts to stimulate the immune system. Preclinical research has investigated HGH's influence on thymic function, lymphocyte proliferation, natural killer cell activity, and cytokine production. The GH receptor is expressed on multiple immune cell types, and the GH–IGF-1 axis is now understood to play an important modulatory role in both innate and adaptive immunity. This has generated research interest in HGH's potential role in immune senescence — the age-associated decline in immune function — given the parallel decline in GH secretion observed with advancing age.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eAgeing \u0026amp; GH Deficiency Research\u003c\/strong\u003e The progressive decline in HGH secretion with age — a phenomenon sometimes termed somatopause — is associated with a well-characterised constellation of metabolic and physiological changes including increased fat mass, reduced lean body mass, decreased bone density, impaired exercise capacity, and reduced quality of life. This relationship has made rhGH an important tool in ageing research, where it is used as a reference compound to investigate the biological consequences of GH deficiency and the mechanistic basis of age-related metabolic decline. Studies comparing GH-replete and GH-deficient animal models have been particularly valuable for delineating the specific contributions of the GH–IGF-1 axis to healthy ageing trajectories.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eCardiovascular Research\u003c\/strong\u003e The GH–IGF-1 axis exerts significant influence on cardiovascular structure and function, and has been studied extensively in both directions — deficiency and excess. In GH-deficient animal models, researchers have observed increased cardiovascular risk markers including dyslipidaemia, endothelial dysfunction, and reduced cardiac output. Conversely, GH excess models have been used to study the pathophysiology of acromegaly-related cardiomyopathy and hypertension. These two poles of the research landscape have contributed to a nuanced understanding of the dose-dependent and receptor-mediated cardiovascular effects of GH signalling.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eNeuroendocrinology \u0026amp; CNS Research\u003c\/strong\u003e GH receptors are expressed in multiple brain regions, and HGH has been investigated in preclinical models of cognitive function, neuroprotection, and neuroendocrine regulation. Research has examined the role of the GH–IGF-1 axis in hippocampal neurogenesis, synaptic plasticity, and the regulation of mood-associated neurotransmitter systems. These findings have contributed to a growing body of evidence suggesting that the age-related decline in GH secretion may have consequences for cognitive and neurological function beyond its well-characterised metabolic effects.\u003c\/p\u003e\n\u003chr class=\"border-border-200 border-t-0.5 my-3 mx-1.5\"\u003e\n\u003ch3 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003eProduct Specifications\u003c\/h3\u003e\n\u003cdiv class=\"overflow-x-auto w-full px-2 mb-6\"\u003e\n\u003ctable class=\"min-w-full border-collapse text-sm leading-[1.7] whitespace-normal\"\u003e\n\u003cthead class=\"text-left\"\u003e\n\u003ctr\u003e\n\u003cth scope=\"col\" class=\"text-text-100 border-b-0.5 border-border-300\/60 py-2 pr-4 align-top font-bold\"\u003eSpecification\u003c\/th\u003e\n\u003cth scope=\"col\" class=\"text-text-100 border-b-0.5 border-border-300\/60 py-2 pr-4 align-top font-bold\"\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003ePeptide\u003c\/td\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003eHGH — Recombinant Human Growth Hormone (rhGH)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003eAlso Known As\u003c\/td\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003eSomatotropin, Growth Hormone (GH)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003eStructure\u003c\/td\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003e191-amino acid single-chain polypeptide, four-helix bundle\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003eMolecular Formula\u003c\/td\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003eC₉₉₀H₁₅₂₈N₂₆₂O₃₀₀S₇\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003eMolecular Weight\u003c\/td\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003e22,124 Da\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003ePurity\u003c\/td\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003e\u0026gt;99% (HPLC \u0026amp; MS verified)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003eForm\u003c\/td\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003eLyophilised powder\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003eVial Sizes\u003c\/td\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003e5mg, 10mg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003eAppearance\u003c\/td\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003eWhite to off-white powder\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003eSolubility\u003c\/td\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003eSoluble in sterile water or bacteriostatic water\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003eStorage\u003c\/td\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003e2–8°C (short-term); –20°C (long-term, lyophilised)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003eShelf Life\u003c\/td\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003e24 months lyophilised; use reconstituted solution within 28 days (2–8°C)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003eCAS Number\u003c\/td\u003e\n\u003ctd class=\"border-b-0.5 border-border-300\/30 py-2 pr-4 align-top\"\u003e12629-01-5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003chr class=\"border-border-200 border-t-0.5 my-3 mx-1.5\"\u003e\n\u003ch3 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003eQuality \u0026amp; Purity Assurance\u003c\/h3\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eEvery batch of our recombinant HGH undergoes a rigorous multi-stage quality control and release process.
