GHRP-2 vs Ipamorelin

Synthetic hexapeptide that stimulates pulsatile growth hormone release from the anterior pituitary by acting on the ghrelin receptor (GHSR-1a). Commonly stacked with GHRH analogs such as CJC-1295 or Sermorelin to amplify GH output synergistically.

GHRP-2 is a synthetic growth hormone secretagogue that triggers natural GH release from the pituitary gland. It is commonly used alongside GHRH analogs to support muscle growth, fat loss, and recovery. For educational purposes only — consult a qualified healthcare provider.

Ipamorelin binds to the ghrelin receptor (GHSR-1a) and stimulates dose-dependent GH release with a clean hormonal profile. Unlike GHRP-6 or hexarelin, it does not significantly stimulate appetite-related pathways or cortisol secretion at standard research doses. This selectivity makes it a frequently studied peptide for protocols where hormonal side-effect profiles are a consideration.

Ipamorelin is a selective growth hormone secretagogue and ghrelin receptor agonist. It stimulates pulsatile GH release from the anterior pituitary with high selectivity — producing minimal effect on cortisol, prolactin, or ACTH compared to earlier GHRPs. It is commonly researched for its role in supporting body composition, recovery, and lean mass maintenance.
