Ipamorelin Research Profile

Ipamorelin is a pentapeptide growth hormone secretagogue that selectively stimulates the release of growth hormone from the pituitary gland via the ghrelin receptor. Unlike older GHRPs, Ipamorelin research has focused on its selective GH release with minimal effect on cortisol or prolactin secretion. Preclinical studies have examined its influence on body composition, bone density, and IGF-1 levels in rodent models. For research use only; not approved for human therapeutic use.

Frequently Asked Questions

Q: Why is Ipamorelin often studied with CJC-1295?
A: Ipamorelin acts on the ghrelin receptor to stimulate GH release, while CJC-1295 acts on the GHRH receptor. Research indicates these two mechanisms work synergistically, producing greater GH secretion when combined than either compound alone. The CJC-1295 + Ipamorelin blend is a popular research formulation for this reason.

Q: How selective is Ipamorelin compared to other GHRPs?
A: Ipamorelin is considered highly selective for GH secretion. Preclinical studies show it does not significantly stimulate ACTH, cortisol, aldosterone, or prolactin at research doses, which distinguishes it from earlier GHRP compounds like GHRP-6.

Q: What purity standard does Official Peptides use for Ipamorelin?
A: All Ipamorelin sold by Official Peptides is verified at ≥99% purity via HPLC. Independent third-party testing documentation is available upon request for every batch.
