GHRP-2, also known as pralmorelin, is a synthetic growth hormone secretagogue, which specifically targets ghrelin (growth hormone receptor). The significance of targeting ghrelin becomes apparent when we see what are its two main effects – growth hormone secretion and meal initiation.
GHRP-2 was a pioneering growth hormone (GH) secretagogue and is currently used to evaluate GH deficiency and secondary adrenal failure.
