What does MOTS-c do? Benefits and evidence

A peptide the body makes; injection benefits and safety remain unproven.

Also called: MOTS-C, Mitochondrial open reading frame of the 12S rRNA-c.

Mitochondrial-derived peptides · 16-amino-acid mitochondrial signaling peptide.

MOTS-c is a small peptide the body makes. People use injections hoping for better energy, exercise performance or fat loss. Human research mostly measures natural peptide levels; a new dosing trial has no posted results. Injection safety and effective doses remain unknown.

  • In mice, it reduced diet-related weight gain and insulin resistance. (animal)
  • In mice, it improved physical ability, even when treatment began in old age. (animal)
  • People report more energy and easier workouts, but no published dosing trial in people shows this. (Reported by users)

Uses in the sources

  • Users report more energy; no published native MOTS-c dosing trial establishes this effect. (Reported by users) (source)
  • People report easier workouts and use before training. Controlled human injection results are absent. (Reported by users) (source)
  • Self-reported fat-loss claims rely on uncontrolled experience; mouse weight results do not establish human weight loss. (Reported by users) (source)
