MOTS-c: A Research Overview

MOTS-c is a mitochondrial-derived peptide — one of the first peptides found to be encoded by mitochondrial DNA rather than the cell nucleus. It is studied in metabolic research and is often described as an “exercise mimetic.” It is a research-use-only compound — not approved for human use.

• What it is: a 16-amino-acid peptide encoded within the mitochondrial 12S rRNA gene.
• Key pathway: activates AMPK, a central regulator of cellular energy.
• Research nickname: “exercise mimetic,” because some effects in models resemble those of physical activity.
• Status: not FDA-approved; research use only.

What is MOTS-c?

MOTS-c is notable because it is encoded by mitochondrial DNA — evidence that mitochondria actively send signaling molecules to the rest of the cell. It circulates in the bloodstream and acts on metabolic tissues, with skeletal muscle appearing to be a primary target in research.

What researchers study

MOTS-c findings come from cell-based and animal models:

• AMPK activation — engaging a master switch of cellular energy balance.
• Glucose handling — enhanced glucose uptake into skeletal muscle in models.
• Exercise signaling — circulating MOTS-c rises with exercise in humans, prompting study of the link.
• Metabolic homeostasis — rodent studies of diet-induced metabolic changes.

Related compounds

MOTS-c is frequently studied alongside other mitochondria-focused materials such as SS-31 and the coenzyme NAD+.

Storage & handling

MOTS-c is supplied lyophilized. Keep it cold and dark, reconstitute only when needed for research, and limit freeze–thaw cycles. See our guide on reconstituting lyophilized peptides.

Research status

MOTS-c is not approved by the FDA or other regulators for human use; the available evidence is preclinical. Treat it strictly as a research compound.
