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. Cold powder reconstituted with room-temperature water can produce localised concentration gradients that slow dissolution.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eStorage after reconstitution:\u003c\/strong\u003e Reconstituted peptides in BAC water should be stored at 2–8°C (refrigerated). 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.

KPV represents the minimal bioactive anti-inflammatory sequence of α-MSH: the C-terminal tripeptide that retains the immunomodulatory and anti-inflammatory activity of the parent molecule while shedding its broader hormonal effects — including melanocortin-mediated pigmentation signalling and adrenal axis activity.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe discovery of KPV's anti-inflammatory properties emerged from systematic structure-activity relationship (SAR) studies of α-MSH conducted in the late 1980s and early 1990s. Researchers seeking to identify the minimal active sequence responsible for α-MSH's immunomodulatory activity progressively truncated the parent molecule and assessed the retained potency of each fragment. The finding that the C-terminal tripeptide Lys-Pro-Val retained potent anti-inflammatory activity — comparable to or approaching that of the full α-MSH tridecapeptide in some experimental models — was a landmark result in the melanocortin research field. It established that a three-amino-acid sequence could recapitulate the core anti-inflammatory function of a thirteen-amino-acid parent hormone, and opened a new avenue of research into ultra-small bioactive peptides as tools for studying inflammatory signalling pathways.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eDespite its minimal size, KPV is an unusually stable research compound. Its tripeptide structure confers inherent resistance to proteolytic degradation compared to larger peptides, and its molecular weight of just 301.38 g\/mol gives it pharmacokinetic and membrane-permeability properties distinct from most research peptides — including the ability to penetrate cellular membranes and act on intracellular inflammatory signalling targets directly. Crucially, research has also identified a specific active transporter mechanism for KPV in intestinal tissue: the PepT1 di\/tripeptide transporter — normally expressed in the small intestine and markedly upregulated in inflamed colonic tissue during inflammatory bowel disease — actively transports KPV into intestinal epithelial and immune cells, providing a disease-directed tissue uptake mechanism of considerable research interest in gastrointestinal inflammatory biology.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eOur KPV 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 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]\"\u003eKPV has been investigated in over fifty peer-reviewed publications spanning more than two decades, with research covering gastrointestinal inflammatory biology, dermatological science, wound healing, mucosal barrier research, and systemic anti-inflammatory pharmacology.

The first is melanocortin receptor engagement — primarily at MC1R and MC3R, which are expressed on immune cells, intestinal epithelial cells, dermal fibroblasts, and multiple other tissue types involved in inflammatory responses. Activation of these receptors suppresses downstream pro-inflammatory signalling cascades, most notably NF-κB (nuclear factor kappa B) — the master transcription factor controlling expression of inflammatory cytokines including TNF-α, IL-1β, IL-6, and IL-8 — and the MAPK (mitogen-activated protein kinase) pathway, which regulates cellular stress responses and inflammatory gene expression.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eHowever, a critical distinction in KPV's mechanism was established by Getting and colleagues in a landmark study examining KPV alongside other melanocortin peptides in a model of crystal-induced peritonitis. While KPV produced significant reduction in polymorphonuclear leukocyte accumulation in the peritoneal cavity — demonstrating meaningful anti-inflammatory activity in vivo — its anti-inflammatory effect was not blocked by the MC3\/4-R antagonist SHU9119, and KPV failed to stimulate cAMP accumulation in macrophages (in contrast to the MC3\/4-R agonist MTII). These findings indicate that KPV's anti-inflammatory activity is not fully explained by classical melanocortin receptor–cAMP signalling, and that additional — possibly receptor-independent or intracellular — mechanisms are operative. This partial mechanistic independence from canonical melanocortin receptor signalling is a defining pharmacological feature of KPV that distinguishes it from full-length α-MSH and has sustained mechanistic investigation into its precise intracellular targets.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003ePepT1-Mediated Intestinal Uptake \u0026amp; Gastrointestinal Research\u003c\/strong\u003e One of the most significant mechanistic findings in KPV research was published in Gastroenterology: the demonstration that KPV's anti-inflammatory effects in intestinal tissue are mediated, at least in part, through active cellular uptake via the PepT1 di\/tripeptide transporter. PepT1 is normally expressed in the small intestine, where it facilitates absorption of dietary di- and tripeptides. Critically, PepT1 expression is markedly upregulated in inflamed colonic tissue during inflammatory bowel disease — a pattern that creates a disease-specific transport mechanism for KPV in the very tissue where it is most needed as a research tool.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eStudies in human intestinal epithelial cell lines (Caco2-BBE and HT29-Cl.19A) and human T cells (Jurkat) demonstrated that KPV — administered at both low (10 nmol\/L) and high doses (100 μmol\/L) — inhibited IL-1β-induced IκB-α degradation in intestinal epithelial cells, suppressing NF-κB activation independently of melanocortin receptor activity. Importantly, α-MSH at the same doses did not significantly alter the kinetics of this response — confirming that the PepT1-mediated intracellular anti-inflammatory effect of KPV in intestinal epithelial cells is a property specific to the tripeptide fragment, and that KPV's mechanism in this tissue is MC receptor-independent. In vivo, KPV administration in murine models of colitis (DSS-induced and TNBS-induced) produced significant reductions in colonic inflammation markers — results that have established KPV as a valuable and widely used research tool in preclinical IBD models.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eInflammatory Bowel Disease \u0026amp; Mucosal Barrier Research\u003c\/strong\u003e KPV's combination of MC1R\/MC3R agonism, NF-κB suppression, MAPK pathway modulation, and PepT1-mediated intestinal uptake has made it one of the most actively studied anti-inflammatory peptides in the IBD and mucosal biology research space. Preclinical studies in rodent colitis models have consistently demonstrated that KPV administration attenuates colonic inflammation, reduces pro-inflammatory cytokine expression (TNF-α, IL-1β, IL-6), preserves mucosal barrier integrity, and improves histological scores of intestinal inflammation. The PepT1 upregulation in inflamed colon provides a natural disease-directed concentration mechanism that enhances KPV's research relevance specifically in models where intestinal inflammation is present — making it an unusually tissue-targeted research tool for gastrointestinal inflammatory biology.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eWound Healing \u0026amp; Tissue Repair Research\u003c\/strong\u003e Beyond its gastrointestinal applications, KPV has been studied in models of wound healing and dermal tissue repair. Research has documented KPV's influence on keratinocyte migration and proliferation, fibroblast activity, and the regulation of inflammatory mediators in the wound microenvironment — effects consistent with α-MSH's established role in cutaneous inflammation and repair signalling via MC1R, which is prominently expressed in skin. Studies in wound healing models have demonstrated KPV-associated improvements in re-epithelialisation and wound closure rates, alongside attenuation of the pro-inflammatory cytokine environment that delays healing in chronic wound models.

It is a first-in-class triple hormone receptor agonist, designed as a single molecule that simultaneously activates three distinct receptors: glucose-dependent insulinotropic polypeptide (GIP), glucagon-like peptide-1 (GLP-1), and glucagon (GCG). This multi-receptor mechanism distinguishes retatrutide from earlier generations of incretin-based research compounds — including GLP-1 mono-agonists such as semaglutide, and dual GIP\/GLP-1 agonists such as tirzepatide — by introducing glucagon receptor activation as an additional metabolic axis.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eStructurally, retatrutide is a 39-amino acid peptide conjugated to a C20 fatty diacid moiety, which confers an extended pharmacokinetic half-life suitable for once-weekly dosing in clinical research settings. Compared to endogenous GLP-1 and glucagon, retatrutide demonstrates lower potency at GLP-1 and glucagon receptors but substantially higher potency at the human GIP receptor — a pharmacological profile deliberately engineered to balance efficacy with tolerability.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eRetatrutide has progressed through Phase 2 clinical trials and into the Phase 3 TRIUMPH programme — one of the most significant and closely watched clinical development programmes in metabolic research. It currently represents the most clinically advanced triple hormone receptor agonist in the scientific literature and is among the most actively researched peptides in the field of metabolic and obesity science.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eOur retatrutide is supplied for research purposes only, synthesised under strict quality-controlled manufacturing conditions and verified to a purity of greater than 99% by High-Performance Liquid Chromatography (HPLC) and Mass Spectrometry (MS). It is provided 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; Clinical Trial Data\u003c\/h3\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eRetatrutide has one of the most substantive and rapidly evolving clinical research profiles of any peptide currently available for laboratory study. The compound has been evaluated in multiple randomised, placebo-controlled trials and has generated results that have been published in leading peer-reviewed journals including the New England Journal of Medicine, The Lancet, and Nature Medicine.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eTriple Receptor Mechanism of Action\u003c\/strong\u003e Retatrutide's triple agonist mechanism operates across three complementary metabolic pathways. GLP-1 receptor activation suppresses appetite, slows gastric emptying, and promotes insulin secretion in a glucose-dependent manner. GIP receptor activation enhances insulin secretion, modulates adipose tissue metabolism, and appears to synergise with GLP-1 activity to produce greater metabolic effects than either hormone alone — as demonstrated by the clinical performance of the dual agonist tirzepatide. The addition of glucagon receptor agonism introduces a third axis: increased energy expenditure, enhanced hepatic fat oxidation, and PCSK9-mediated reduction in LDL cholesterol. The net result of this triple activation is a broader and potentially more powerful metabolic response than earlier generation single or dual receptor agonists.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003ePhase 2 Obesity Trial — New England Journal of Medicine (2023)\u003c\/strong\u003e The pivotal Phase 2 obesity trial of retatrutide, published in the New England Journal of Medicine, enrolled 338 adults with obesity (BMI ≥30) or overweight with weight-related comorbidities. Participants received once-weekly subcutaneous retatrutide at doses of 1 mg, 4 mg, 8 mg, or 12 mg, or placebo, for 48 weeks. The results were notable even by the elevated standards of the modern incretin era. At 48 weeks, participants on the 8 mg dose achieved a mean body weight reduction of 22.8%, while those on the highest 12 mg dose achieved a mean reduction of 24.2% — compared to just 2.1% in the placebo group. Notably, 100% of participants in both the 8 mg and 12 mg groups achieved at least 5% body weight reduction, with 83% of the 12 mg group achieving reductions of 15% or more.

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.

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.
