GHRP-2 Acetate
GHRP-2 (Pralmorelin) is a synthetic hexapeptide that stimulates GH secretion by activating the ghrelin receptor (GHSR-1a) on pituitary somatotrophs. It is one of the most potent GH secretagogues in its class, though less selective than Ipamorelin — it can moderately affect cortisol, prolactin, and appetite signaling in research models.
