Ipamorelin vs GHRP-6
Side-by-side comparison of research status, mechanisms, pharmacokinetics, and administration routes.
Ipamorelin is a selective growth hormone secretagogue and ghrelin receptor agonist. Unlike other GHRPs, it stimulates GH release with high selectivity — producing minimal cortisol, ACTH, or prolactin elevation. It is among the most studied GHRPs for its clean GH pulse profile, making it a preferred research peptide for GH axis studies with reduced side effect concern.

GHRP-6 is one of the original synthetic GHRPs, acting as a strong ghrelin receptor agonist. It produces robust GH release accompanied by significant appetite stimulation — a property that makes it both valuable for cachexia research and distinct from cleaner GHRPs like Ipamorelin. Research also shows cytoprotective and cardioprotective properties independent of GH secretion.
