Ipamorelin: A Research Guide
Ipamorelin is studied as a highly selective growth hormone secretagogue, one that stimulates GH release without the cortisol or prolactin elevation seen with earlier-generation compounds in this class.

Mechanism
Earlier secretagogues such as GHRP-2 and GHRP-6 raise cortisol alongside growth hormone, which can promote fat storage and muscle catabolism. Ipamorelin's selectivity profile avoids that trade-off. Research also shows increased slow-wave sleep within two weeks of study initiation, the sleep phase associated with peak natural GH release and muscle protein synthesis.
Reconstitution & Storage
This compound is supplied as a lyophilized powder and reconstituted with bacteriostatic water before use. See the calculator on our FAQ page for concentration and draw volume based on your vial size and target dose.
