About GHRP-6
GHRP-6 (Growth Hormone Releasing Peptide-6) is a synthetic hexapeptide and GHSR agonist. It is one of the earliest GH secretagogues studied in research and has served as a benchmark compound for comparing newer GHRPs. Unlike more selective peptides like Ipamorelin, GHRP-6 significantly raises ghrelin — producing notable appetite stimulation alongside GH release — and can elevate cortisol and prolactin.
GHRP-6 is sold worldwide as a research-use-only (RUO) compound. It is sold as a lyophilized powder and is often compared to GHRP-2 and Ipamorelin in GH-axis research. Third-party HPLC and mass spectrometry COAs remain the key signal when comparing suppliers.

Particle PeptidesGHRP-6 vs GHRP-2 vs Ipamorelin
Three classic GHSR agonists studied in GH-axis research — with distinct selectivity and side-effect profiles:
- GH release potency — GHRP-2 generally produces the strongest GH pulse; GHRP-6 is moderate; Ipamorelin produces a cleaner but slightly smaller pulse
- Ghrelin / appetite — GHRP-6 raises ghrelin significantly, causing notable hunger; GHRP-2 and Ipamorelin have less appetite effect; this is the defining characteristic of GHRP-6 research
- Cortisol & prolactin — GHRP-2 raises both the most; GHRP-6 moderate elevation; Ipamorelin has minimal cortisol or prolactin effect — the key reason it is considered more selective
- Half-life — GHRP-6 and GHRP-2 ~15–60 minutes; Ipamorelin ~2 hours
Frequently Asked Questions
What is GHRP-6?
GHRP-6 (Growth Hormone Releasing Peptide-6) is a synthetic hexapeptide GHSR agonist. It is studied in research for growth hormone release, though it also raises ghrelin (causing appetite stimulation) and elevates cortisol and prolactin — making it less selective than newer GHRPs like Ipamorelin.
Where can I buy GHRP-6?
GHRP-6 is sold by research peptide suppliers worldwide. The suppliers above ship to the United States, EU, UK, and other regions with available lab data and certificates of analysis.
What is the difference between GHRP-6 and GHRP-2?
Both are hexapeptide GHSR agonists. GHRP-2 generally produces a stronger GH pulse but also elevates prolactin and cortisol more. GHRP-6 has a stronger appetite-stimulating effect through ghrelin. Both are considered less selective than Ipamorelin for GH-only research.
How is GHRP-6 different from Ipamorelin?
Ipamorelin is a pentapeptide with high selectivity — it stimulates GH release with minimal cortisol, prolactin, or ghrelin elevation. GHRP-6 is less selective and significantly raises ghrelin (causing hunger) and can spike cortisol. Ipamorelin has a longer half-life (~2 hours vs ~15–60 minutes for GHRP-6).
