Recombinant Human Growth Hormone (rhGH, Somatropin) is a 191-amino acid single-chain polypeptide produced by recombinant DNA technology, identical to the endogenous growth hormone secreted by the anterior pituitary somatotrophs. GH exerts its biological effects through the growth hormone receptor (GHR) and downstream JAK-STAT signaling, stimulating IGF-1 production, promoting linear growth, protein synthesis, lipolysis, and carbohydrate metabolism regulation. As one of the most important hormones in human physiology, recombinant HGH is essential for research in growth disorders, metabolic syndrome, body composition, aging, and tissue repair. It is clinically approved for treatment of GH deficiency, Turner syndrome, chronic kidney disease, and other conditions.

Recombinant Human Growth Hormone (somatropin) is a 191-amino acid protein identical to natural pituitary GH, produced by recombinant DNA technology for research applications.
Our wholesale rhGH is ≥98% purity, verified by SDS-PAGE, HPLC, and bioassay.
Applications include growth physiology, GHR signaling, body composition, metabolic research, and aging studies.
Store at 2-8°C protected from light, or at -20°C for long-term storage. Avoid repeated freeze-thaw cycles.
Contact our team for MOQ and volume pricing on research-grade rhGH.
HGH is the actual hormone itself, while secretagogues (like GHRP-2, Ipamorelin) stimulate the body's own production. Research-grade HGH allows direct study of GH's effects.
