GHRP-2 (Growth Hormone Releasing Peptide-2) is a synthetic growth hormone secretagogue that binds to the ghrelin/growth hormone secretagogue receptor (GHS-R). By activating this receptor, GHRP-2 stimulates the natural release of growth hormone from the pituitary gland.

Research studies have demonstrated that GHRP-2 can enhance muscle growth, support immune system regulation, and promote healthier sleep cycles. Notably, GHRP-2 also exhibits oral bioactivity, a rare trait among peptide therapeutics, making it a potential candidate for non-injectable applications in future research settings.
