Pal-AHK vs KPV
Side-by-side comparison of key properties, dosing, and research.
- Summary
- Pal-AHK is the palmitoylated form of the AHK-Cu copper tripeptide, created by attaching a palmitic acid chain to enhance skin penetration and lipid bilayer affinity. The palmitoyl modification significantly improves dermal bioavailability compared to unmodified AHK, making it particularly effective in anti-aging and hair growth formulations.
- KPV is a naturally occurring anti-inflammatory tripeptide derived from the C-terminal of alpha-MSH. It powerfully suppresses intestinal and systemic inflammation via melanocortin receptors, making it valuable for IBD, gut healing, and wound repair.
- Half-Life
- Extended (lipid depot effect in stratum corneum)
- Short half-life (~15–30 minutes), but effects persist longer due to receptor-level anti-inflammatory cascades
- Admin Route
- Topical
- Oral, SubQ, Topical
