Full research summary5 citations

GHRP-6 is the original ghrelin-mimetic growth-hormone secretagogue, a GHS-R1a agonist that triggers a GH pulse and powerfully stimulates hunger. Same GH mechanism as GHRP-2 with a much bigger appetite kick, which is why it is favored for gaining-phase work and set aside when cutting. Combined with a GHRH analog, the GH release is far larger than either alone.

Storage & handling

Freeze-dried at -4F; in solution, 36 to 46F and best within 28 days, with potency fading over roughly 3 to 4 weeks (structure-based estimate, no published data).

Research cautions

Active malignancy of any kind is an absolute contraindication (GH and IGF-1 can promote tumor growth), and the strong appetite stimulation is flagged as a driver of poor glycemic control with sustained use.
