Somatotropin · Growth & Regeneration

Human Growth Hormone (HGH) — also known as Somatotropin — is a 191-amino acid peptide hormone naturally secreted by the anterior pituitary gland. It is the master regulator of growth, cellular regeneration, and metabolic function in the human body. As one of the most extensively researched peptides in scientific literature, HGH underpins a wide spectrum of physiological processes — from skeletal development to adult tissue maintenance and recovery.

At Peptigain, our HGH is supplied as a pharmaceutical-grade lyophilised powder and comes complete with 10ml of Bacteriostatic Water — included with every order so your research is ready to go from the moment it arrives. Bacteriostatic Water is the gold standard diluent for reconstituting HGH, preserving peptide integrity and extending vial usability for up to 28 days once reconstituted.

In the research context, HGH stimulates IGF-1 production in the liver, which mediates many of its anabolic and regenerative effects. Its influence spans muscle protein synthesis, adipose tissue lipolysis, connective tissue repair, immune modulation, and cognitive function.
