Ipamorelin: Research on the Selective Growth Hormone Secretagogue and Its Ghrelin Receptor Profile
Ipamorelin is a selective synthetic pentapeptide that stimulates GH release through the ghrelin receptor (GHS-R1a) without significantly elevating cortisol, ACTH, or prolactin — a selectivity profile that distinguishes it from earlier GHRPs. This research overview covers its mechanism, preclinical findings in GH axis and GI motility research, and published human clinical data.
