GHRP-2
Growth Hormone

GHRP-2 (Pralmorelin) is a synthetic hexapeptide growth hormone releasing peptide and one of the most potent first-generation GHRPs. It stimulates pituitary GH secretion via the ghrelin receptor (GHSR-1a) with greater potency than GHRP-6, while producing less appetite stimulation....
