Overview
Ipamorelin is a selective growth hormone secretagogue and ghrelin receptor (GHS-R) agonist comprising five amino acids. Distinguished from other GH secretagogues by its high receptor selectivity, Ipamorelin stimulates GH release with minimal impact on cortisol, prolactin, or ACTH in animal models — making it an important research tool for studying clean, selective somatotropic axis modulation. It is frequently paired with CJC-1295 in GHRH/GHRP combination studies.
