GHRP-2 5mg

GHRP-2 is a synthetic hexapeptide growth hormone secretagogue that binds to the growth hormone secretagogue receptor (GHS-R1a), also known as the ghrelin receptor. In experimental models, GHRP-2 activates Gq/PLC and calcium-dependent intracellular signaling pathways that regulate growth hormone release and hypothalamic–pituitary axis feedback. Preclinical research has investigated its role in somatotropic signaling, sleep-related neuroendocrine pathways, immune-associated peptide signaling, and receptor pharmacology, including evaluation of non-injectable exposure routes under controlled laboratory conditions.
