GHS hexapeptide · 2-Me-Trp.
Hexarelin is a synthetic hexapeptide growth hormone secretagogue — structurally similar to GHRP-6 with a methyl substitution that increases ghrelin receptor affinity. Developed by Mediolanum Farmaceutici in Italy. Supplied as research-grade material with 3rd-party HPLC verification and full Certificate of Analysis per lot.
Hexarelin is a synthetic hexapeptide growth hormone secretagogue — structurally similar to GHRP-6 with a methyl substitution that increases ghrelin receptor affinity. Developed by Mediolanum Farmaceutici in Italy.
Binds GHSR1a with higher affinity than GHRP-6, producing a more robust GH release in published comparative studies. Notably, hexarelin is also reported to bind CD36 scavenger receptor B (non-GH-receptor mediated activity) — a distinguishing property explored in cardiovascular research.
Investigated both as a GH secretagogue and as a cardioprotective agent in preclinical models via the CD36 pathway. Not FDA-approved. 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.
Hexarelin is a 6-residue peptide with molecular formula C47H58N12O6 and molecular weight of approximately 887.0 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).
Investigated both as a GH secretagogue and as a cardioprotective agent in preclinical models via the CD36 pathway. Not FDA-approved. 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.
