MOTS-c vs AICAR: What’s the Difference?
The main difference between MOTS-c and AICAR is mechanism: MOTS-c is studied for metabolic flexibility and exercise mimetic research — Mitochondrial-derived peptide. AICAR is studied for exercise mimetic research — Activates AMPK, increasing glucose uptake, fatty acid oxidation, and mitochondrial biogenesis.
