Research Mechanism Summary
GHRP-2 (pralmorelin) is a synthetic hexapeptide that stimulates GH secretion by binding GHS-R1a (ghrelin receptor) on pituitary somatotrophs and hypothalamic arcuate nucleus neurons, activating protein kinase C and cAMP pathways as well as voltage-gated Ca2+ channels (https://pubmed.ncbi.nlm.nih.gov/9331879/). Unlike ipamorelin, it also stimulates ACTH and cortisol release at pharmacological doses, reflecting its less selective receptor profile (https://pubmed.ncbi.nlm.nih.gov/9849822/). In preclinical models it synergizes additively with GHRH to amplify GH pulse amplitude, and has been evaluated as a GH deficiency diagnostic provocation agent in clinical research (https://pubmed.ncbi.nlm.nih.gov/15230633/).
