CJC-1295 vs Argireline
Side-by-side comparison of key properties, dosing, and research.
Growth Hormone Peptides
CJC-1295Skin & Cosmetic
Argireline- Summary
- CJC-1295 is a synthetic GHRH analog that stimulates the pituitary gland to produce and release growth hormone. The DAC (Drug Affinity Complex) version has a markedly extended half-life. The No DAC version (Modified GRF 1-29) preserves natural pulsatile GH release and is preferred in most protocols.
- Argireline is the most widely researched topical 'Botox-alternative' cosmetic peptide, an acetylated hexapeptide that inhibits neuromuscular transmission to relax facial muscles and reduce dynamic wrinkle depth by 17–27% in clinical studies.
- Half-Life
- ~30 minutes (No DAC) / 6–8 days (with DAC)
