Ipamorelin (Aib-His-D-2Nal-D-Phe-Lys-NH2) is a synthetic pentapeptide ghrelin receptor agonist with a molecular weight of 711.85 g/mol. It was specifically engineered for selectivity, stimulating GH release via the ghrelin receptor (GHSR-1a) with minimal off-target effects on cortisol, prolactin, or ACTH secretion observed at research concentrations.
This receptor selectivity profile distinguishes ipamorelin from earlier GHRP compounds (GHRP-2, GHRP-6) and has made it one of the most commonly referenced GH secretagogue peptides in the published literature. Research has examined its effects in GH deficiency models, age-related GH decline, anabolic signaling, and muscle satellite cell studies.
