Ipamorelin is a short-chain peptide that interacts specifically with the ghrelin or growth hormone secretagogue receptor. Recognized as one of the most selective growth hormone (GH) stimulators available, it has been demonstrated in lab research to have no measurable influence on ACTH, prolactin, FSH, LH, TSH, or cortisol secretion. Due to its precise targeting, ipamorelin has attracted attention not only as a potential therapeutic agent but also as a model compound for studying selective GH receptor activation. Its activity is closely associated with promoting growth and regeneration in musculoskeletal tissues.
