Ipamorelin is a synthetic pentapeptide and selective agonist of the growth-hormone secretagogue receptor (ghrelin receptor) in the pituitary and hypothalamus. It triggers GH release without the cortisol, prolactin, or appetite stimulation associated with earlier ghrelin mimetics.
Its clean receptor profile makes Ipamorelin a frequent reference compound when isolating GH-axis effects from confounders.
