HGH (Somatropin) 100 IU — Recombinant Human Growth Hormone for Research
Human Growth Hormone (HGH/Somatropin) is a 191-amino acid polypeptide hormone synthesized and secreted by the anterior pituitary gland. As one of the most comprehensively studied hormones in medical science — with decades of clinical application, thousands of peer-reviewed studies, and well-defined physiological mechanisms — somatropin remains a foundational subject in endocrinology, anti-aging medicine, body composition science, and metabolic health research.
H&J Pharma supplies recombinant HGH (Somatropin) at 100 IU per vial with HPLC-verified ≥99% purity for qualified research applications.
Product Overview
Recombinant human growth hormone is bioidentical to pituitary-derived GH, produced via recombinant DNA technology in bacterial or mammalian cell expression systems. It binds to GH receptors throughout the body, stimulating IGF-1 production, activating anabolic pathways in muscle and bone, promoting lipolysis in adipose tissue, and regulating carbohydrate metabolism. GH secretion is highest during sleep and exercise, declines significantly with age (somatopause), and plays a central role in the biology of healthy aging.
Key Benefits
- Lean mass support — stimulates muscle protein synthesis and nitrogen retention
- Fat metabolism — promotes lipolysis and reduces visceral adiposity
- Bone mineral density — increases osteoblast activity and bone formation
- IGF-1 upregulation — drives downstream anabolic and regenerative signaling
- Recovery and wound healing — GH is essential for tissue repair mechanisms
- Metabolic regulation — influences glucose metabolism and insulin sensitivity
- Cardiac function — studied for its role in cardiac muscle maintenance
- Anti-aging research — somatopause and GH replacement are central to longevity science
Popular Use Cases
Somatropin research spans endocrinology, anti-aging medicine, body composition science, sports physiology, pediatric growth disorders, and adult GH deficiency management. The landmark 1990 NEJM study by Rudman et al. demonstrating body composition improvements in older men with GH administration sparked decades of longevity research into GH replacement therapy.
Who Commonly Uses This
Endocrinologists, sports medicine researchers, anti-aging scientists, body composition researchers, and longevity physicians represent the primary research communities for HGH. Its well-established pharmacology and clinical track record make it one of the most referenced hormones in performance and longevity research.

Research & Scientific Interest
Somatropin is one of the most extensively studied hormones in medicine. Landmark research includes its GH deficiency applications, body composition improvements in aging adults (Rudman 1990), its IGF-1-mediated anabolic effects, and its complex role in metabolic regulation. Ongoing research explores GH’s role in cognitive function, cardiovascular health, immune aging, and the biology of somatopause.
Frequently Asked Questions
Somatropin is recombinant human growth hormone (rHGH) — a 191-amino acid protein identical to naturally produced pituitary growth hormone. It is one of the most extensively studied hormones in medicine, with broad research applications spanning body composition, metabolism, bone density, and aging.
IU (International Unit) is the standard measurement for HGH potency. Approximately 3 IU equals 1mg of somatropin by weight, though this ratio varies slightly by formulation and testing method.
Key research areas include: body composition (lean mass increase, fat mass reduction), bone mineral density, GH deficiency in adults, IGF-1 axis regulation, cardiac function, metabolic syndrome, recovery and wound healing, and anti-aging biology.
Store lyophilized HGH at 2–8°C, away from light and heat. Do not freeze. Once reconstituted with sterile water, store at 2–8°C and use within 3–4 weeks.
No. This product is sold strictly for laboratory and research purposes only. Somatropin for human use requires a prescription.
Yes. H&J Pharma offers same-day shipping with next-day delivery across Vietnam.
