Overview
GHRP-2 (generic name pralmorelin) is a synthetic hexapeptide growth hormone secretagogue and a second-generation cousin of GHRP-6. It is an agonist at the ghrelin / growth hormone secretagogue receptor (GHS-R1a), binding that receptor in the pituitary and hypothalamus to drive a pulse of growth hormone release. It was designed to be more potent and somewhat cleaner than GHRP-6, with a milder effect on appetite. It is licensed in Japan as a diagnostic agent for growth hormone deficiency, making it the only GH secretagogue in this class with regulatory approval. Outside that narrow diagnostic use it has no approval and is sold elsewhere only as a research compound.
