GHRP-2

Research-Grade

GHRP-2 (also called pralmorelin or KP-102) is a synthetic hexapeptide growth-hormone-releasing peptide, a second-generation analog that improved on GHRP-6's potency. It is a potent GHSR-1a agonist and has been used diagnostically in Japan and Korea as a GH-stimulation test. Its GH-releasing potency is comparable to or slightly greater than Ipamorelin's. The drawback compared to Ipamorelin is meaningful prolactin and cortisol elevation at GH-effective doses, limiting its appeal for chronic off-label use where selectivity matters. Clinical development for therapeutic GH deficiency indications did not advance to FDA approval. Commercial availability is limited to diagnostic use in some Asian markets.
