CJC-1295 vs Lonapegsomatropin (Skytrofa)
An educational, source-based comparison of CJC-1295 and Lonapegsomatropin (Skytrofa) — how each peptide works, what it's researched for, and what to know before going deeper.
A synthetic analog of growth hormone-releasing hormone (GHRH). The non-DAC version has a short half-life that preserves pulsatile GH release, while DAC variants extend the half-life via albumin binding. Research focuses on stimulating endogenous GH and IGF-1 production via the pituitary.
- Endogenous GH pulse amplitude
- IGF-1 elevation
- Body composition in adult GH-deficient research
- Sleep architecture (slow-wave sleep)
- • GH-axis manipulation may affect glucose tolerance.
- • Banned in competitive sport (WADA).
- • Requires physician oversight in any therapeutic context.
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).
