GHRP-6 (Growth Hormone Releasing Peptide-6) is a synthetic hexapeptide that stimulates the release of growth hormone (GH) by activating the ghrelin receptor (GHS-R1a). It significantly boosts GH and IGF-1 levels, aiding in muscle growth, fat metabolism, recovery, and anti-aging effects.
Unlike GHRP-2, GHRP-6 is known for strongly increasing appetite, making it useful in situations where weight or mass gain is desired.
