Ipamorelin is a synthetic pentapeptide, a short chain of five modified amino acids built to act selectively on the ghrelin receptor (GHS-R1a). It is best known in research for how it engages this receptor on the pituitary, and its clean, selective binding is what sets it apart from broader secretagogues.
It also has a solid research base, with work exploring how it triggers growth-hormone secretagogue receptor signaling (Raun et al., 1998, European Journal of Endocrinology). That makes it a common reference peptide in this area of study.
