How does MOTS-c work?
Mitochondrial-derived peptide encoded inside the 12S rRNA region. Activates AMPK signaling (the metabolic 'energy sensor') and improves insulin sensitivity in skeletal muscle. In plain terms, MOTS-c is aimed at metabolism and exercise performance. A mitochondrial-derived peptide that targets metabolic flexibility, insulin sensitivity, and exercise response. Mechanistic detail like this comes largely from preclinical and early research, the human picture is limited.
What people use it for
- Users on a cut wanting metabolic support
- People with insulin-resistance markers
- Endurance athletes
