Why people use MOTS-c for metabolic health
Pre-diabetic markers, insulin resistance creeping in. MOTS-c? The honest answer: the animal evidence is genuinely strong, but the human trials are still thin. MOTS-c is a 16-amino-acid peptide your mitochondria release under metabolic stress (Lee et al., 2015).
This page covers what's known, what's not, and what the editorial take is for normal humans considering MOTS-c for metabolic health.
What the evidence says
Evidence tier: Strong animal evidence. Decades of consistent animal evidence; human RCTs are sparse but the mechanism is well-established.
- MOTS-c is a 16-amino-acid peptide your mitochondria release under metabolic stress (Lee et al., 2015).
- Animal models showed improved insulin sensitivity and protection against diet-induced obesity.
- Often called an 'exercise mimetic' (a drug that mimics some effects of exercise) in longevity coverage.
Protocol notes
5-10mg subcutaneous 2-3 times per week for 4-8 weeks. Coordinate with a longevity-focused clinician.
Always with a sports-medicine doctor, telehealth provider, or specialist sign-off. Self-experimenting on injection schedules without clinical input is the most common way people waste money and get hurt.
What to skip
- Vendors without a Certificate of Analysis (COA). Random gym-bro vendors with no third-party testing. The peptide market has a quality-control problem; the answer is COA per peptide, every time.
- Pre-mixed blends from non-pharmacy sources. Compounding pharmacies that produce pre-mixed combinations with COAs are fine. Random vendor "stack vials" are not.
- Massively over-dosed protocols. More is rarely better with peptides. Receptor saturation is real. Stick to evidence-based dosing.
