GHRP-6 (Growth Hormone-Releasing Peptide-6) is a synthetic hexapeptide (His-D-Trp-Ala-Trp-D-Phe-Lys-NH₂) that functions as a potent growth hormone secretagogue by binding to the ghrelin receptor (GHS-R1a). As one of the original GH secretagogues developed, GHRP-6 has an extensive research history and is well-characterized in the scientific literature.

GHRP-6 stimulates GH release through mechanisms distinct from GHRH, and the two pathways act synergistically when combined. Research indicates GHRP-6 produces significant dose-dependent increases in growth hormone and IGF-1 levels, with effects observable within 15-30 minutes of administration. A notable characteristic of GHRP-6 is its activation of appetite-stimulating pathways through ghrelin receptor activation, which has made it a useful tool for studying the relationship between GH secretion and appetite regulation.
