Research Overview
Somatropin
Somatropin is the best-studied growth hormone peptide, with decades of clinical use in pediatric and adult GH deficiency. Trials consistently show increases in IGF-1 and growth velocity, with adverse effects mainly reflecting excessive GH exposure.
hGHRH(1-40)OH
Human GHRF(1-40)OH has been studied to understand how truncation of the native hormone changes biological potency and half-life. It is a common research tool for mapping minimal active sequences within the GHRH family.
