Overview

A growth-hormone-releasing peptide that strongly stimulates GH, with mild appetite and prolactin effects.

Mechanism of action

Agonist at the ghrelin/GHS receptor on the pituitary, amplifying GH pulses.

Typical protocol

100–300 mcg subQ, 1–3× daily, often paired with a GHRH like CJC-1295.

Storage

Reconstituted: refrigerated, ~30 days.
