Hexarelin

Growth Hormone

Hexarelin's defining research application — one of the most potent GH secretagogues studied, alongside a distinct cardioprotective mechanism.

Growth hormone stimulation

Its core, defining mechanism — high-potency ghrelin receptor activation producing a stronger GH pulse than milder secretagogues like Ipamorelin.

Cardioprotection

Activates cardiac-specific binding sites independent of its GH-releasing activity, a dual mechanism distinguishing it from other GHRPs.

Muscle growth

Supports lean muscle development through its strong GH and downstream IGF-1 elevation, most effective when paired with training.
