Hexarelin is the most potent of the common GHRPs — comparable studies showed GH responses larger than GHRH alone or hexarelin alone, with consistent dose-response (Loche et al. 1995). The cost of that potency is faster receptor desensitization, which is why community protocols typically cycle 4 weeks on / 4 weeks off rather than running continuous.
Research-context information only. Hexarelin is a research peptide on the FDA 503A bulks Category 2 list. Protocols, doses, and reactions reported below come from published research and self-reported community sources. This article reports what has been documented, not what should be done. Consult a licensed physician for personal medical decisions.
This guide covers documented per-mg pricing, COA verification, vial size selection, and red flags. For dosing context, see the hexarelin dosing guide.

How to Verify Hexarelin Quality
What a COA Should Include
Identity Confirmation
Mass spec confirming 887.46 Da for hexarelin
Sequence verification — His-D-2-Methyl-Trp-Ala-Trp-D-Phe-Lys-NH2
2-methyl-tryptophan modification verified (the modification distinguishes hexarelin from GHRP-6)
Purity Testing
HPLC purity at 98%+
Single dominant peak
Contamination Testing
Endotoxin levels
Residual solvent analysis
Heavy metals screening
How to Verify a COA Is Legitimate
Third-party lab — Janoshik, MZ Biolabs, Colmaric most-cited
Verifiable task number
Recent date (within 6 months)
Batch match
887 Da mass confirmation — 872 Da indicates GHRP-6 (no methylation), 817 Da indicates GHRP-2
Red Flags to Avoid
No COA available
Only in-house testing
Prices below $3/mg — likely substituted with cheaper GHRP-6
No mass spec
No 2-methyl-tryptophan verification
