What it is

MOTS-c is a mitochondrial-derived peptide: a short peptide encoded not by the cell nucleus but by mitochondrial DNA. Its discovery was an important scientific finding: mitochondria were not thought to produce signalling peptides that act on the rest of the body. Research so far is in mice, there are no human efficacy trials yet, and it is not approved as a medicine.

It is one of the most discussed compounds in longevity research.
