What Is MOTS-c?
MOTS-c is a 16-amino-acid peptide encoded not in the nucleus but in mitochondrial DNA — one of a small class of 'mitochondrial-derived peptides' discovered in the 2010s. It acts as a metabolic signal, activating AMPK, the cellular energy-stress pathway that exercise itself triggers.
That mechanism earned it the 'exercise mimetic' label: rodent studies show improved insulin sensitivity, endurance and resistance to diet-induced obesity. Human data is early — a small Japanese trial and observational work linking MOTS-c levels to metabolic health.
What is MOTS-c studied for?
- •Insulin sensitivity and glucose metabolism
- •Exercise capacity and endurance (animal models)
- •Metabolic syndrome and obesity resistance
- •Longevity research as a mitochondrial signal
Side effects & safety
Sparse reporting; community use suggests good tolerability with occasional injection-site redness. As a metabolic signaling molecule, long-term unknowns dominate the risk picture.
Legal & approval status
Research chemical; no approvals. WADA-banned (metabolic modulator category).
