Ipamorelin
Growth hormone releasing peptide (GHRP)
Mechanism of Action
Stimulates ghrelin receptors to release growth hormone. Considered one of the mildest GHRPs with fewer side effects.
Ipamorelin is a research compound (not FDA-approved) that stimulates ghrelin receptors to promote growth hormone release. Self-reported data from 112 individuals across 253 reports suggests dominant areas of interest are body composition (40.2%) and sleep quality (24.1%) — outpacing direct GH elevation (21.4%) as a primary focus.
