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.
Cheapest recommended vendor: Dynamic Peptide's 2mg vial at $34.99 ($17.50/mg) — the lowest effective $/mg from a recommended vendor. Compare current vendors ↓
Practical implication: A 5mg vial fits the typical 4-week-on cycle at standard doses. 10mg vials require staged reconstitution at lower doses.

Frequently Asked Questions
Is hexarelin legal to buy?
Hexarelin is sold as a research peptide labeled 'not for human consumption.' It is not FDA-approved. Purchasing research peptides is legal in most US jurisdictions.
How much does hexarelin cost per month?
Community subcutaneous protocols use 100-200mcg twice daily. Monthly mass at 200mcg×2/day is 12mg. Research-vendor 5mg vials run $30-65 and 10mg vials run $50-110. Monthly cost ranges from $50-130.
Why does hexarelin produce tachyphylaxis faster than other GHRPs?
Hexarelin produces the largest acute GH spike of any common GHRP, but the receptor desensitizes faster. Community protocols typically run 4-week cycles with 4-week off periods to manage desensitization. Continuous use produces declining responses within 2-3 weeks.
What vial size should I buy?
5mg vials are the most-cited size for the typical 4-week-on/4-week-off cycling pattern. 10mg vials are common for users running back-to-back cycles.
What purity should I look for in hexarelin?
Third-party HPLC at 98%+ purity, plus mass spec confirming 887.46 Da. Hexarelin is a 6-residue peptide (His-D-2-Methyl-Trp-Ala-Trp-D-Phe-Lys-NH2) with 2-methylation on a tryptophan — a small modification that distinguishes it from GHRP-6.
Can I buy hexarelin from a compounding pharmacy?
Not legally in the US. Hexarelin is on the FDA 503A bulks Category 2 list. Research vendors are the only documented commercial source.
