AICAR vs MOTS-c

AICAR vs MOTS-c — mechanism, half-life, dosing, and research status compared. Which is right for your protocol?

AICAR
Mitochondrial & Longevity

AICAR (Acadesine) is a cell-permeable adenosine analog that is phosphorylated intracellularly to ZMP - a structural mimic of AMP that directly activates AMP-activated protein kinase (AMPK). AMPK is the master metabolic switch triggered by exercise, fasting, and caloric restrictio...

MOTS-c
Mitochondrial & Longevity

MOTS-c is a 16-amino acid mitochondrial-derived peptide encoded within mitochondrial DNA, functioning as a mitohormone. It enhances insulin sensitivity, improves exercise capacity, and may extend healthspan. Plasma levels decline with age and metabolic disease. Phase I research s...
