AICAR vs Pal-AHK
Side-by-side comparison of key properties, dosing, and research.
- Summary
- AICAR is a cell-permeable AMP analog that activates AMPK (AMP-activated protein kinase) — the master metabolic switch that triggers fat burning, mitochondrial biogenesis, and adaptations normally only achieved through exercise. It has been called the 'exercise in a pill' compound.
- 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.
