Research Overview
Ipamorelin is a synthetic pentapeptide and potent growth hormone secretagogue (GHS) that acts as a selective agonist at the ghrelin receptor (GHS-R1a). It was developed to have high selectivity for GH release without significantly stimulating prolactin, cortisol, or ACTH secretion — a property that distinguishes it from first-generation GHRP compounds such as GHRP-2 and GHRP-6.
Research has characterized ipamorelin as one of the most selective GHRPs available, with studies demonstrating its ability to stimulate pulsatile GH release in both in vitro and in vivo systems. Its clean selectivity profile has made it a preferred research tool for studying the ghrelin receptor axis in isolation from other hypothalamic-pituitary pathways.
Ipamorelin has been examined in studies of GH-dependent processes including IGF-1 regulation, bone turnover, fat metabolism, and muscle protein synthesis in animal models. Its short plasma half-life (~2 hours) and lack of receptor desensitization at physiological doses have made it a widely used research reference compound.
