In short: Hexarelin is a synthetic hexapeptide growth hormone secretagogue, structurally related to GHRP-6, studied in pre-clinical models for its action at both the ghrelin receptor (GHS-R1a) and the CD36 scavenger receptor. It is supplied strictly for in-vitro laboratory research and is not approved for human consumption. Research buyers should confirm any material against three criteria before purchase: ≥99% purity by HPLC, identity confirmed by mass spectrometry, and clear batch numbering tied to a certificate of analysis.
What is Hexarelin?
Hexarelin is a synthetic hexapeptide in the growth hormone-releasing peptide (GHRP) family, closely related in structure to GHRP-6 but modified for greater metabolic stability. Like other GHRPs it is a ghrelin-mimetic secretagogue and is handled in the laboratory as a lyophilised powder reconstituted for in-vitro assay work. A distinguishing feature studied in research models is its interaction with two receptor populations rather than one.
What does the research investigate?
Pre-clinical and in-vitro research into hexarelin has examined two pathways: GH-release signalling via the growth hormone secretagogue receptor (GHS-R1a), and separate cardiac-tissue effects attributed to the CD36 scavenger receptor in rodent and cell models. Animal models of myocardial ischaemia have been used to study CD36-mediated effects that appear, in those models, to operate independently of growth hormone release. These findings are drawn from cell cultures and animal studies only and do not establish safety or efficacy in humans. Always read the primary sources directly.
Purity and quality: what research buyers should check
- ≥99% purity by HPLC — confirm via the batch certificate of analysis (COA).
- Identity confirmed by mass spectrometry against the expected peptide mass.
- Batch numbering that ties each vial to its COA for traceability.
Vexar Lab supplies Hexarelin as a pack of 10 vials, ≥99% HPLC-verified, batch-numbered, with mass-spec confirmation.
Handling and storage
Standard lyophilised-peptide practice applies. Store sealed vials of lyophilised powder at -20°C, away from light and moisture. After reconstitution with a suitable solvent, refrigerate and use within a short working window, avoiding repeated freeze-thaw cycles that can degrade peptide integrity. Allow vials to reach room temperature before opening to limit condensation.
Wholesale supply
Vexar Lab supplies research peptides in packs of 10 vials, £300 minimum order, with bulk pricing on volume, £45 flat worldwide shipping, and optional custom labelling for resellers.
Frequently asked questions
Is Hexarelin approved for human use?
No. Hexarelin is supplied strictly for in-vitro laboratory research and is not approved for human consumption or any therapeutic use.
What makes hexarelin distinct in research models?
Pre-clinical studies describe activity at both GHS-R1a and the CD36 receptor; the CD36-linked cardiac effects are investigational and model-dependent, not human findings.
How should purity be verified?
Request the batch certificate of analysis showing ≥99% purity by HPLC and a mass-spectrometry identity confirmation tied to the vial’s batch number.
