About Ipamorelin
Ipamorelin is a synthetic pentapeptide and selective GHSR (growth hormone secretagogue receptor) agonist. Unlike older GHRPs, Ipamorelin is studied for its selectivity: it stimulates growth hormone release without significantly elevating cortisol, prolactin, or ghrelin in research settings. Its approximate half-life is 2 hours.
Ipamorelin is frequently used in research alongside GHRH analogs such as CJC-1295 or Sermorelin to study GH pulse synergy. It is sold worldwide as a research-use-only (RUO) compound. Purity and consistency vary between suppliers, making third-party lab data essential when comparing options.

Peptide CentreIpamorelin vs GHRP-6 vs Sermorelin
All three are studied as GH-stimulating compounds but with distinct mechanisms and pharmacokinetic profiles:
- Receptor class — Ipamorelin and GHRP-6 are GHSR agonists (ghrelin receptor); Sermorelin is a GHRH receptor agonist — a fundamentally different pathway
- Selectivity — Ipamorelin is highly selective: minimal cortisol or prolactin elevation; GHRP-6 significantly raises ghrelin (appetite) and can spike cortisol; Sermorelin is selective but GHRH-based
- Half-life — Ipamorelin ~2 hours; GHRP-6 ~15–60 minutes; Sermorelin ~10 minutes
- Common research pairing — Ipamorelin is frequently paired with CJC-1295 or Sermorelin to study synergistic GH pulse amplification
Frequently Asked Questions
What is Ipamorelin?
Ipamorelin is a synthetic pentapeptide GHSR (growth hormone secretagogue receptor) agonist. It is studied in research for selective growth hormone release without significant cortisol, prolactin, or ghrelin elevation seen with older GHRPs.
Where can I buy Ipamorelin?
Ipamorelin is sold by multiple research peptide suppliers. The suppliers above ship to the United States, UK, Europe, and Australia, with available lab data and certificates of analysis.
What should I look for in an Ipamorelin supplier?
Look for third-party COAs (HPLC and mass spectrometry), endotoxin and heavy-metals testing, transparent batch documentation, and consistent community reviews.
How is Ipamorelin different from GHRP-6 or Sermorelin?
Ipamorelin is a selective GHSR agonist with a ~2-hour half-life and no significant cortisol or prolactin spike. GHRP-6 raises ghrelin and hunger substantially. Sermorelin is a GHRH analog with a much shorter half-life (~10 min). Each has a distinct mechanism and research profile.
