MOTS-c (Mitochondrial Open Reading frame of the Twelve S rRNA-c) is a 16-amino-acid peptide encoded by mitochondrial DNA, not nuclear DNA. It is considered a 'mitochondrial hormone' that regulates energy metabolism, insulin sensitivity and physical endurance. Its levels decline with age and are associated with obesity, type 2 diabetes and loss of muscle function.

MOTS-c is one of the few peptides encoded by mitochondrial DNA rather than nuclear DNA. This 16-amino-acid peptide is studied as a 'mitochondrial hormone' that signals to the rest of the cell about energy status, which is the basis for its research interest in metabolism and physical endurance.
Research observes that circulating MOTS-c declines with age, a pattern associated with obesity, type 2 diabetes and loss of muscle function. This age-related decline is one reason MOTS-c is studied in the context of metabolic anti-aging.
Reconstituting 10 mg in 2 mL of bacteriostatic water yields 5 mg/mL, which equals 50 mcg per insulin unit (UI). On this basis a 1 mg dose corresponds to 20 UI (0.20 mL), using the universal formula UI = (dose in mg ÷ 0.05).
Reference protocols describe a 4–8 week cycle compatible with intermittent fasting and HIIT training, because MOTS-c is studied as an exercise-mimetic peptide that engages the same metabolic adaptations as physical training. This makes it of research interest where mitochondrial function and aerobic capacity are the focus.
