Ipamorelin is a synthetic pentapeptide and selective growth hormone secretagogue that acts through the growth hormone secretagogue receptor (GHSR). Its distinctive research profile is its relative selectivity for stimulating growth hormone (GH) release compared with some broader-acting growth hormone secretagogues. Research applications include GH secretion dynamics, GHSR signaling, and related endocrine mechanisms.
