What is Hexarelin?
Hexarelin (His-DTrp-Ala-Trp-DPhe-Lys-NH₂) is a synthetic hexapeptide GHSR-1a agonist producing the highest GH pulse amplitude of any synthetic GHRP. Uniquely, hexarelin also binds the CD36 scavenger receptor in cardiac tissue — providing GH-independent cardioprotection via PI3K/Akt signalling. CAS 140703-51-1.
Research Applications
Maximum GH Pulse
Highest intrinsic GHSR-1a efficacy — strongest GH release of all GHRPs
CD36 Cardiac Research
GH-independent cardioprotection — PI3K/Akt — unique among synthetic GHRPs
Cardiac IR Protection
LAD ligation models — infarct size reduction via CD36
GHSR-1a Selectivity
High-efficacy reference vs ipamorelin selective arm
GH Axis Desensitisation
Receptor downregulation kinetics with high-dose agonist
