Ipamorelin
GH release
A selective growth-hormone secretagogue peptide—stimulates GH with less appetite spike than older GHRPs.
Ipamorelin binds ghrelin receptors and triggers pituitary GH release without strongly raising cortisol or prolactin. Clinics pair it with CJC-1295 for anti-aging and body-composition goals. Not FDA-approved for OTC use; …
Sermorelin
GH release
A GHRH analog that prompts the pituitary to release growth hormone—often stacked with GHRP peptides in clinic and research conversations.
Sermorelin mimics the first 29 amino acids of growth-hormone-releasing hormone. It stimulates pulsatile GH release rather than supplying GH directly. It was FDA-approved as a diagnostic (Geref) but is widely discussed of…

Common questions
What is the difference between Ipamorelin and Sermorelin?
Both are categorized under GH release in our directory—here is how they differ in name, use, and label context. Ipamorelin is categorized as GH release; Sermorelin as GH release. Ipamorelin: A selective growth-hormone secretagogue peptide—stimulates GH with less appetite spike than older GHRPs. Sermorelin: A GHRH analog that prompts the pituitary to release growth hormone—often stacked with GHRP peptides in clinic and research conversations.
Are Ipamorelin and Sermorelin 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—Ipamorelin or Sermorelin?
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.
