MOTS-c
A mitochondria-derived peptide studied for metabolism and exercise capacity.
Overview
A 16-amino-acid peptide encoded in mitochondrial DNA. In mice it improves insulin sensitivity, protects against diet-induced obesity and boosts exercise capacity. Human data is just starting.
How it works
Activates AMPK and shifts cellular metabolism, mimicking some exercise effects.
Evidence
2/5
Mostly mouse studies; very early human work (levels rise with exercise).
Half-life
Short
Known as
Mitochondrial ORF of the 12S rRNA-c

Math only: concentration (mg/mL) = vial mg ÷ mL of water; units = dose (mg) ÷ concentration × 100. Always double-check against your own vial label and a clinician. This tool does not recommend a dose.
Reconstitution
Diluent: Bacteriostatic water (0.9% benzyl alcohol) — allows multiple draws from one vial.
- Wipe both vial tops with an alcohol swab and let dry.
- Draw the diluent, then inject it slowly down the inside wall of the vial — never straight onto the powder.
- Swirl gently or let it sit; do not shake. Foam can damage peptides.
- Solution should be clear. Cloudy, stringy or discolored = discard.
- Common mix: 10 mg + 2 mL = 5 mg/mL (5 mg = 100 units).
Storage
Powder
Freezer / fridge
Keep sealed vial in the freezer (−20 °C) for long-term storage; fridge (2–8 °C) is fine for a few weeks. Keep dry and out of light.
After mixing
~28 days
Refrigerate at 2–8 °C. Never freeze after mixing. Keep upright, capped, and out of light.
Travel
Keep cool
Short trips at room temperature are generally fine for powder; keep mixed vials cold.
- Large dose volumes — consider a 1 mL syringe.
Side effects & cautions
Reported side effects
- Injection-site irritation
- Fatigue
- Occasional flushing
Cautions
- Limited human safety data.
- Monitor blood sugar if using diabetes medication.
FDA & international status
Not FDA-approved
Research-stage only; no clinical approval anywhere.
Regulations change often — verify with the FDA, EMA, MHRA, Health Canada, TGA and WADA before acting.

FAQ
Do doses really reach 5 mg?
Yes — community doses are high compared to most peptides, so vial size and cost matter.
