GHRP-2
GH release
A growth-hormone secretagogue peptide from the GHRP family—stronger GH pulse than ipamorelin, with more appetite stimulation.
GHRP-2 binds ghrelin receptors to trigger GH release from the pituitary. It is more potent than ipamorelin for GH output but often causes noticeable hunger. Like other GHRPs it is not FDA-approved for athletic or anti-ag…
GHRP-6
GH release
An older GH secretagogue known for strong GH release—and notable hunger side effects.
GHRP-6 was among the first synthetic ghrelin mimetics. It reliably raises GH but also increases appetite and cortisol more than ipamorelin. Still used in research and some clinic protocols, but largely superseded for wel…

Common questions
What is the difference between GHRP-2 and GHRP-6?
Both are categorized under GH release in our directory—here is how they differ in name, use, and label context. GHRP-2 is categorized as GH release; GHRP-6 as GH release. GHRP-2: A growth-hormone secretagogue peptide from the GHRP family—stronger GH pulse than ipamorelin, with more appetite stimulation. GHRP-6: An older GH secretagogue known for strong GH release—and notable hunger side effects.
Are GHRP-2 and GHRP-6 the same peptide?
No. They are different molecules with distinct names on labels and in research databases. Always match the full INCI or drug name—not a nickname on the front of the package.
Which is better for performance—GHRP-2 or GHRP-6?
Neither page is medical or anti-doping advice. Research peptides discussed in fitness communities may be prohibited in tested sport or unavailable as OTC supplements. Verify WADA lists and talk to a clinician.
