What Ipamorelin is
Ipamorelin is a growth hormone secretagogue (GHRP). A pentapeptide ghrelin-receptor agonist studied for selective growth hormone release with minimal effect on cortisol or prolactin, which distinguishes it from earlier GHRPs.
Class and mechanism
Ipamorelin is a growth hormone secretagogue (GHRP). A pentapeptide ghrelin-receptor agonist studied for selective growth hormone release with minimal effect on cortisol or prolactin, which distinguishes it from earlier GHRPs.
Where it sits
Growth hormone itself and the secretagogues that prompt its release are different things. Somatropin is the hormone. A secretagogue acts on the GHRH or ghrelin receptor to raise the body's own output.
Worth knowing
Commonly paired with CJC-1295 because the two act on different receptors - a GHRH analogue alongside a ghrelin-receptor agonist.
