MOTS-C
MOTS-c — The Mitochondrial Peptide
- Supports metabolic function
- Activates AMPK
- Supports exercise capacity
Overview
MOTS-c is a 16-amino-acid mitochondrial-derived peptide, encoded not in nuclear DNA but within the mitochondrial 12S rRNA gene — one of a small group of peptides the mitochondria themselves produce. It is supplied as a lyophilised powder in a sealed vial for laboratory and in-vitro research.
PepSource supplies MOTS-c in 10mg and 40mg vials. Every batch is independently third-party tested for HPLC purity and mass-spectrometry identity, and the certificate of analysis for the batch you receive is published on our lab results page.

Research Focus
MOTS-c is studied primarily as a metabolic regulator. Published research has examined its activation of AMPK, the cellular energy sensor; insulin sensitivity and glucose metabolism; exercise capacity, where studies in aged mice reported improved physical performance; and mitochondrial function and metabolic homeostasis during ageing. It is one of the peptides that connects mitochondrial biology to whole-body metabolism, which is why it appears so often in longevity research.
Research on MOTS-c is predominantly in animal models and in-vitro studies; human clinical data is limited. Our summary of the published literature is here: SS-31, MOTS-c & NAD+ Dosage: What Studies Show.
Testing & Certificates of Analysis
Each batch is tested by an independent analytical laboratory for HPLC purity and mass-spectrometry identity before release. Certificates are published per batch and searchable by lot code on our lab results page — you can verify the exact vial you were sent.
