Peptides

MOTS-c

Evidence: Emerging (strong preclinical)

Mechanism of Action

MOTS-c is a 16-amino acid mitochondrial-derived peptide encoded by the 12S rRNA gene of the mitochondrial genome. It primarily acts through the folate-AICAR-AMPK pathway: by regulating the folate cycle and de novo purine biosynthesis, it increases AICAR accumulation, which phosphorylates and activates AMPK. This enhances glucose uptake in skeletal muscle, improves insulin sensitivity, and mimics exercise-mediated physiological responses. Skeletal muscle MOTS-c levels increase 11.9-fold in response to acute exercise in young men.

Dosing Protocol

Standard: Research indicates 5-10 mg administered 3-5 times per week via subcutaneous injection.

Loading: Research indicates 10 mg daily for the first 1-2 weeks.

Maintenance: Research indicates 5 mg three times weekly.

Administration: subcutaneous

Timing: Morning administration preferred. Can be dosed pre-workout for enhanced exercise performance.

Duration: 8-16 week cycles.

Notes

MOTS-c is one of the most exciting mitochondrial-derived peptides, functioning as a genuine exercise mimetic. It was discovered by Dr. Changhan Lee at USC. The 11.9-fold increase in skeletal muscle MOTS-c after exercise suggests it is a key mediator of exercise benefits. MOTS-c levels decline with age, correlating with metabolic decline. The 5-Amino-1MQ + MOTS-c fat loss stack combines NNMT inhibition with AMPK activation for comprehensive metabolic optimization. MOTS-c also shows anti-aging and insulin-sensitizing properties beyond fat loss.

Stacking

  • 5-Amino-1MQ
  • AOD-9604
  • Semaglutide

Interactions

  • Metformin [LOW] — Both activate AMPK; potentially synergistic but monitor for excessive AMPK activation.
  • 5-Amino-1MQ [LOW] — Complementary fat loss stack — MOTS-c for AMPK/exercise mimicry, 5-Amino-1MQ for NNMT/NAD+.
  • Insulin [MEDIUM] — MOTS-c improves insulin sensitivity; may potentiate insulin effects and risk hypoglycemia.
  • May potentiate antidiabetic medications
  • Synergistic with exercise

Contraindications

  • Pregnancy and breastfeeding
  • Type 1 diabetes (insulin sensitivity changes require monitoring)
  • Not FDA-approved
  • Limited human safety data
  • Active cancer (metabolic pathway activation)

Side Effects

  • Injection site reactions
  • Mild fatigue post-injection
  • Transient flushing
  • Muscle soreness (exercise-mimetic effect)
