Ipamorelin is a synthetic pentapeptide (Aib-His-D-2-Nal-D-Phe-Lys-NH2) and a potent, selective secretagogue of growth hormone (GH). It belongs to the class of Growth Hormone Releasing Peptides (GHRPs) and acts as a selective agonist of the ghrelin/growth hormone secretagogue receptor (GHS-R). Unlike other GHRPs, it demonstrates high specificity for GH release without significantly elevating cortisol, prolactin, or ACTH levels. Research applications include investigations into muscle tissue regeneration, bone mineral density, and metabolic adaptation.
