Hexarelin vs Lonapegsomatropin (Skytrofa)
An educational, source-based comparison of Hexarelin and Lonapegsomatropin (Skytrofa) — 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.
Prodrug of somatropin with a transient PEG linker that releases unmodified GH over ~1 week, providing once-weekly dosing for pediatric GH deficiency.
- Pediatric growth hormone deficiency
- • FDA-approved.
- • Same class warnings as daily GH (intracranial hypertension, scoliosis progression, glucose intolerance).
