What Is GHRP-6?

GHRP-6 is the original first-generation GH-releasing peptide from the 1980s — the molecule that proved the ghrelin receptor could be drugged. It releases GH robustly and stimulates appetite dramatically, being the closest functional mimic of ghrelin, the hunger hormone itself.

That hunger effect defines its niche: bodybuilders in mass phases use it deliberately as an appetite amplifier, while everyone else moved on to molecules that skip it.

What is GHRP-6 studied for?

Side effects & safety

Intense hunger within minutes is near-universal. Otherwise the GHRP profile: water retention, mild cortisol/prolactin bump, tingling. The hunger makes fat-loss protocols essentially incompatible.

Legal & approval status

Research chemical; no approvals. WADA-banned.

Typical dosing at a glance

Commonly reported protocols use 100 mcg–300 mcg, 1–3x daily, via subcutaneous injection. For the mixing math — how much bacteriostatic water, exact syringe units, doses per vial — see the GHRP-6 reconstitution calculator →
