GH secretagogue · original.
GHRP-6 was the first growth hormone-releasing peptide with clinically measurable activity, developed by Cyril Bowers from met-enkephalin-derived analogs. It is the prototype that led to the development of later GHRPs including GHRP-2, hexarelin, and ipamorelin. Supplied as research-grade material with 3rd-party HPLC verification and full Certificate of Analysis per lot.

GHRP-6 is an agonist of the GHSR1a (ghrelin receptor), stimulating GH release from anterior pituitary. Unlike later analogs (e.g. ipamorelin), GHRP-6 is reported in the literature to produce notable appetite stimulation — an effect linked to its ghrelin-receptor agonism in hypothalamic circuits.
Used extensively in research contexts as a ghrelin receptor ligand. Not FDA-approved. Reported side effects at research doses include increased appetite, mild transient cortisol rise, and occasional prolactin elevation. WADA prohibited (S2).
The above summarizes published research literature. This is not medical advice, a protocol, or a recommendation for use. This compound is supplied for laboratory research only.
GHRP-6 is a 6-residue peptide with molecular formula C46H56N12O6 and molecular weight of approximately 872.0 Da.
The full structural data and release specifications are in the Compound Profile section above. Every lot ships with an independently verified Certificate of Analysis.
Each lot is independently verified by a 3rd-party analytical laboratory (STERIS Labs, Alcami Analytical, or equivalent) before release. Release specification is HPLC purity ≥ 99.5% (typical > 99.8%), mass spectrometry identity match within ±0.5 Da, water content < 5.0% Karl Fischer, and endotoxin < 0.25 EU/mL by LAL (USP <85>).

All compounds ship at ambient temperature in discreet, tamper-evident packaging. Lyophilized peptide powder is stable at room temperature for typical transit windows, which is why research-grade vendors ship this way. Tracked; signature not required.
Store unopened lyophilized product at 2–8°C protected from light. Once reconstituted, most peptides are stable at 2–8°C for approximately 28 days (compound-dependent).
Used extensively in research contexts as a ghrelin receptor ligand. Not FDA-approved. Reported side effects at research doses include increased appetite, mild transient cortisol rise, and occasional prolactin elevation. WADA prohibited (S2).
All PeptideBros compounds are sold strictly as chemical reference materials for in-vitro laboratory research. They are not for human consumption.
HPLC-verified. Mass-spec confirmed. Ambient-stable transit. The paperwork other vendors hope you never ask for.
