Product Information
Hexarelin | Potent GH Secretagogue and CD36 Ligand — Research Grade
Hexarelin (His-D-2-MeTrp-Ala-Trp-D-Phe-Lys-NH2) is a synthetic hexapeptide and the most potent GHS-R1a agonist of the GHRP class. It uniquely also binds CD36, a scavenger receptor expressed in cardiac tissue, enabling research into cardioprotective mechanisms independent of GH release.
Mechanism of Action
- GHS-R1a agonism — highest GH-stimulating potency in the hexapeptide GHS class
- CD36 receptor binding — activates CD36 in cardiomyocytes, studied for myocardial protection in ischaemia models
- Cardioprotective — preclinical data shows reduction in infarct size and preservation of cardiac function via CD36-dependent pathways
- GH desensitisation — chronic administration studies show pituitary desensitisation, distinguishing it from Ipamorelin
Research Areas
Hexarelin is studied in GH deficiency, cardiac ischaemia-reperfusion injury, myocardial protection, and GHS pharmacology. Its dual receptor profile makes it unique among GH secretagogues for cardiovascular research applications.

★★★★★
2 verified reviews DP
Ipamorelin quality confirmed via QC
Internal verification confirmed COA data. Purity was 98.6% HPLC. Peptide behavior in our assay was consistent with published data. Will order again for next study phase.
BS
Consistent performance for research
AOD-9604 arrived quickly and in excellent condition. Cold pack preserved temperature. COA was thorough. Results in metabolic assays consistent with expected parameters.
