Overview
MOTS-C is a 16-amino-acid mitochondrial-derived peptide that functions as a metabolic regulator. The peptide “promotes metabolic homeostasis and reduces obesity and insulin resistance” through activation of AMPK pathways.
What It Is
MOTS-C operates as a cellular “stress signal” that optimizes energy utilization during nutrient scarcity or physical exertion. It activates AMPK through inhibition of the folate cycle, causing AICAR accumulation. This activation shifts cells into energy-efficient mode by:
– Enhancing glucose uptake and fatty-acid oxidation
– Improving mitochondrial respiration
– Downregulating fat storage and gluconeogenesis
– Upregulating antioxidant and stress-response genes via nuclear translocation
Key Research Findings
Preclinical Evidence (No Human Clinical Trials Completed):
– Prevents diet-induced insulin resistance in mouse models
– Reduces visceral fat and prevents obesity through increased energy expenditure
– Mitigates metabolic decline in post-menopausal models
– Enhances exercise capacity; aged mice demonstrated “2× longer” treadmill endurance
– Reduces hepatic fat accumulation and supports cardiac function
– Promotes bone health and modulates immune aging
Dosage Protocol
Reconstitution
– Vial Size: 5 mg
– Diluent: 3.0 mL bacteriostatic water
– Final Concentration: ~1.67 mg/mL
– Storage (Reconstituted): 2–8 °C (refrigerated); use within 7 days
Gradual Titration Schedule
| Weeks | Daily Dose | Units (U-100 syringe) |
|---|---|---|
| 1–2 | 200 mcg | 12 units (0.12 mL) |
| 3–4 | 400 mcg | 24 units (0.24 mL) |
| 5–6 | 600 mcg | 36 units (0.36 mL) |
| 7–8 | 800 mcg | 48 units (0.48 mL) |
| 9–10+ | 1,000 mcg | 60 units (0.60 mL) |
Administration
– Frequency: Once daily
– Route: Subcutaneous injection
– Cycle Duration: 8–12 weeks (extendable to 16 weeks)
– Site Rotation: Abdomen, thighs, upper arms to prevent lipohypertrophy
Reconstitution Steps
1. Draw 3.0 mL bacteriostatic water with sterile syringe
2. Inject slowly down vial wall; avoid foaming
3. Gently swirl/roll until dissolved (do not shake vigorously)
4. Label with reconstitution date
5. Refrigerate at 2–8 °C, protected from light
Storage Instructions
Lyophilized (Powder):
– Temperature: −20 °C (−4 °F) or below
– Environment: Dry, dark conditions
– Include desiccant if available
After Reconstitution:
– Temperature: 2–8 °C (refrigerated)
– Duration: Use within 7 days for optimal potency
– Avoid freeze-thaw cycles
– Allow vials to reach room temperature before opening
Injection Technique
– Clean vial stopper and injection site with alcohol; allow to dry
– Pinch skinfold; insert needle at 90° (45° if lean)
– Do not aspirate for subcutaneous injections
– Inject slowly over several seconds
– Withdraw at same angle; apply gentle pressure if bleeding
– Rotate sites systematically
– Use new sterile syringe for each injection
– Dispose in sharps container
Supplies Needed (Example: 8-Week Protocol)
– MOTS-C Vials: ~6 vials (5 mg each)
– U-100 Insulin Syringes: ~56 syringes (7 per week)
– Bacteriostatic Water: ~2 × 10 mL bottles
– Alcohol Swabs: ~2 × 100-count boxes
Lifestyle Complementary Strategies
– Balanced, protein-forward diet tailored to energy requirements
– Combine resistance training and aerobic activity
– Prioritize 7–9 hours sleep
– Implement stress management techniques
– Consider intermittent fasting or caloric restriction
Reported Preclinical Benefits
– Improved insulin sensitivity and glucose metabolism
– Reduced visceral fat accumulation
– Enhanced physical performance and exercise capacity
– Decreased hepatic steatosis
– Improved cardiac function
– Osteoblast promotion; inhibition of osteoclast formation
– Modulation of immune aging markers
Important Safety Notes
– Research Use Only: No human clinical trials completed to date
– A modified analog (CB4211) showed “good tolerability” in Phase 1 testing
– Discontinue and consult healthcare provider if concerning symptoms develop
– Always rotate injection sites
– Never reuse needles
– Do not aspirate during subcutaneous injection
– Document daily dose and injection site for consistency tracking
