GH Secretagogues
GHRP-2
Scientific Profile
GHRP-2 (D-Ala-D-Phe-Ala-Trp-D-Phe-Lys-NH2) is a synthetic hexapeptide that functions as a growth hormone secretagogue. In vitro studies demonstrate its selective binding to growth hormone secretagogue receptor (GHS-R1a), stimulating GH release through Gq-coupled signaling pathways.
Animal research indicates GHRP-2 induces dose-dependent GH secretion without significantly affecting other pituitary hormones. The peptide demonstrates resistance to enzymatic degradation due to its D-amino acid content.
