MOTS-c

MOTS-c is a small natural peptide made in the mitochondria that helps the body manage energy and respond to stress. It supports better use of fats and sugars for fuel and is studied for its role in metabolism, endurance, and healthy aging. Early research suggests it may improve exercise performance and energy balance, but human data are still limited.

Description

• MOTS-c (Mitochondrial Open Reading Frame of the 12S rRNA type-c) is a 16-amino-acid peptide encoded by mitochondrial DNA.
• Regulates metabolic homeostasis and cellular adaptation to stress through activation of AMPK pathways.
• Studied for roles in insulin sensitivity, energy regulation, and healthy aging.

How It Works

• Activates AMPK, enhancing glucose utilization and fatty acid oxidation.
• Improves mitochondrial efficiency and reduces oxidative stress.
• Acts as a signaling molecule linking mitochondrial activity to nuclear metabolism.

Documented Effects

• Increases glucose uptake and insulin sensitivity in skeletal muscle.
• Improves endurance and exercise tolerance in preclinical models.
• Protects against diet-induced obesity and insulin resistance in animal studies.
• May enhance metabolic flexibility and cellular resilience under stress.

Theoretical Effects

• May support energy balance and mitochondrial health in humans.
• Potential use in metabolic, anti-aging, or performance enhancement research.
• No approved therapeutic use; all human effects remain investigational.

Pharmacokinetics

• Half-life: Approximately 2 hours post subcutaneous injection (based on limited animal data).
• Peak activity: 1–3 hours after administration.
• Elimination: Rapid degradation via peptide-cleaving enzymes; minimal systemic accumulation.

Reconstitution

• Use only bacteriostatic water to mix the lyophilized powder.
• Example vial: 10 mg of MOTS-c
• Choose reconstitution volume based on dosing convenience:
  • 1 mL water → 10 mg/mL → 1 mg per 10 units
  • 2 mL water → 5 mg/mL → 500 mcg per 10 units
• Swirl gently to dissolve; avoid shaking.
• Store reconstituted solution refrigerated (2–8°C). Discard after ~30 days for stability.

Injectable Dosage Overview (Research Reference)

Typical Starting Dose

• Injectable (off-label, anecdotal): ~5–10 mg subcutaneous (SC) per week, divided into smaller doses.
• Conservative entry point: ~2.5 mg twice weekly to assess tolerance.

Common Research Range

• Typical reports: 5–15 mg total weekly, SC or intramuscular (IM) administration.
• Used primarily for metabolic support, fatigue reduction, or endurance enhancement research.

Maximum Weekly Dose

• Anecdotal upper limit: ~15 mg per week.
• Higher doses lack clinical validation and show no confirmed added benefit.

Standard Cycle Length

• Light research use: 4–6 weeks continuous, then evaluate response.
• Extended use: 8–12 weeks with observation of energy and recovery markers.

Clinical Notes

• Administer subcutaneously, preferably in the morning or pre-exercise.
• May be combined with exercise or caloric restriction for synergistic results.
• Stable for about 30 days when refrigerated (2–8°C). Protect from light and heat. Avoid freezing.

Safety Notes

• Begin with a low dose to assess individual response and tolerance.
• Possible effects: mild energy increase, transient warmth, or enhanced endurance.
• Maintain sterile injection practice and verify compound purity.
• Long-term safety in humans not established.
