Research record
Overview
Compound name: Hexarelin
Alternative names: Examorelin
Compound classification: Synthetic peptide; growth hormone–releasing peptide (GHRP)
Brief factual description: Hexarelin is a synthetic hexapeptide classified as a growth hormone secretagogue. It is studied for its strong ability to stimulate endogenous growth hormone release through ghrelin receptor activation.
Mechanism of Action
Primary biological targets: Growth hormone secretagogue receptor (GHS-R1a)
Affected systems: Endocrine (growth hormone and IGF-1 axis)
Receptor selectivity: Potent GHRP with broader activity than newer selective analogues
Downstream signaling effects: Induces pulsatile growth hormone release from the pituitary gland, leading to secondary increases in IGF-1 signaling.
