Overview
GHRP-2 is a growth hormone-releasing peptide that stimulates the pituitary gland to release growth hormone through ghrelin-related receptors. It is commonly associated with recovery, body composition, sleep support, and muscle maintenance. GHRP-2 may also influence appetite and other hormone pathways, which makes it different from more selective growth hormone peptides. Its purpose is to increase natural GH signaling rather than directly introduce growth hormone into the body. As a hormone peptide, GHRP-2 is often discussed for its role in growth hormone stimulation, recovery enhancement, and metabolic support.
