Research Overview
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.
Capromorelin
Research consistently shows capromorelin activates the ghrelin receptor pathway and increases food intake. Human development has been less prominent than veterinary use, but the compound remains a relevant GH secretagogue prototype.
