What is GHRP-2?
GHRP-2 (Growth Hormone Releasing Peptide-2) is a synthetic hexapeptide belonging to the growth hormone secretagogue family. It functions as a ghrelin receptor (GHS-R1a) agonist, stimulating pulsatile growth hormone release from the pituitary gland. GHRP-2 activates protein kinase C and mobilizes intracellular calcium while operating independently of the cAMP pathway. Unlike GHRP-6, it produces less pronounced effects on appetite stimulation, making it particularly valuable for research focused on GH release mechanisms without confounding hunger variables.
