Hexarelin vs Mecasermin (Increlex)
An educational, source-based comparison of Hexarelin and Mecasermin (Increlex) — how each peptide works, what it's researched for, and what to know before going deeper.
A synthetic hexapeptide and potent GHS-R agonist. Stimulates GH release more strongly than GHRP-6 and shows cardioprotective signaling in preclinical ischemia-reperfusion models, partly independent of GH.
- GH release
- Cardiac ischemia-reperfusion (preclinical)
- Left ventricular function in animal models
- • Not FDA-approved.
- • Tachyphylaxis with prolonged use.
- • Prohibited by WADA.
Recombinant human insulin-like growth factor-1 (rhIGF-1) that binds IGF-1 receptors to promote linear growth in children with severe primary IGF-1 deficiency or GH gene deletion with anti-GH antibodies.
- Severe primary IGF-1 deficiency
- Growth failure with GH gene deletion and neutralizing GH antibodies
- • FDA-approved.
- • Hypoglycemia — must be taken with food.
- • Tonsillar hypertrophy, intracranial hypertension reported.
