About HGH
Somatropin — the 191-amino-acid polypeptide identical in sequence to the hormone produced by the anterior pituitary.
Human growth hormone (hGH, somatropin) is a single-chain polypeptide of 191 amino acids secreted by somatotroph cells of the anterior pituitary. Recombinant somatropin, produced in engineered E. coli or mammalian cell lines, carries the identical primary sequence to the endogenous hormone — the distinction that separated it from the earlier cadaver-derived pituitary extracts withdrawn in 1985.
Growth hormone sits at the top of a signalling cascade rather than acting alone: much of its downstream effect is mediated by hepatic IGF-1, which makes the GH/IGF-1 axis one of the most studied endocrine systems in the literature.
Research mechanism
Published research on growth hormone centres on:
- GH receptor dimerisation — a single hormone molecule bridges two receptors, triggering JAK2/STAT5 signalling
- Hepatic IGF-1 induction — the principal mediator of GH's anabolic and growth-promoting effects
- Lipolysis — direct action on adipocytes, extensively documented in body-composition literature
- Nitrogen retention and protein synthesis in skeletal muscle models
- Counter-regulatory glucose effects — the basis of a large insulin-sensitivity research literature
Research applications
- GH/IGF-1 axis signalling research
- Body-composition and lean-mass study models
- Endocrine and pituitary-function research
- Metabolic and insulin-sensitivity investigation
- Assay development and hormone reference work
- Comparative studies against GH secretagogues

Frequently asked questions
How is HGH supplied?
Each REVIVE unit is a 108 IU lyophilized somatropin vial. A lot-specific Certificate of Analysis is available on request ahead of dispatch. Store refrigerated at 2–8°C and protect from light.
How should HGH be stored?
Unlike the lyophilized peptides in our catalog, which are held at −20°C, somatropin is stored at 2–8°C and protected from light. It ships in insulated cold-chain packaging with a temperature indicator.
How does HGH differ from a GH secretagogue like Tesamorelin?
HGH is the hormone itself and acts directly on GH receptors. Tesamorelin is a GHRH analogue that stimulates the pituitary to release its own growth hormone, so its effect is pulsatile and depends on intact pituitary function. Both appear in the GH-axis literature but are mechanistically distinct.
