MOTS-c Dosage Protocols
MOTS-c dosing differs from most peptides in two important ways: the doses are notably higher (milligrams rather than micrograms), and timing relative to exercise can amplify the peptide's effects. This is because MOTS-c is a mitochondrial-derived signaling peptide that activates AMPK — the same metabolic switch triggered by physical activity — rather than a high-potency receptor agonist.
| Protocol | Dose | Frequency | Duration | Best For |
|---|---|---|---|---|
| Standard metabolic | 5 mg | 5× weekly | 4–8 weeks | General metabolic health, insulin sensitivity |
| Performance-focused | 10 mg | 3–5× weekly | 8–12 weeks | Exercise enhancement, body composition |
| Anti-aging | 5 mg | 3× weekly | 8–12 weeks | Mitochondrial support, longevity markers |
| Exercise-synergy | 5–10 mg | Pre-exercise only | 8–12 weeks | Amplifying exercise metabolic response |
Starting Protocol for Beginners
If you are new to MOTS-c, start conservatively:
- Week 1: 5 mg subcutaneously, 3× weekly, to assess tolerance
- Week 2-3: Increase to 5 mg, 5× weekly if well-tolerated
- Week 4+: Consider increasing to 10 mg if targeting performance or body composition goals

Reconstitution & Preparation
MOTS-c comes as a lyophilized (freeze-dried) powder, typically in 5 mg or 10 mg vials. Standard reconstitution with bacteriostatic water:
| Vial Size | BAC Water | Concentration | Draw for 5 mg | Draw for 10 mg |
|---|---|---|---|---|
| 5 mg | 1 mL | 5 mg/mL | 1.0 mL (full syringe) | N/A — need 2 vials |
| 10 mg | 1 mL | 10 mg/mL | 0.5 mL (50 units) | 1.0 mL (full syringe) |
| 10 mg | 2 mL | 5 mg/mL | 1.0 mL (full syringe) | 2.0 mL (two draws) |
Because MOTS-c requires relatively large volumes per dose compared to microgram-dosed peptides, the 10 mg vial with 1 mL reconstitution is the most practical option — it delivers 5 mg per 0.5 mL draw.
Use the peptide calculator for exact volumes and the bacteriostatic water calculator for water amounts. See the reconstitution guide for step-by-step preparation.
Timing: Exercise Synergy & Circadian Considerations
MOTS-c timing is more nuanced than most peptides because of its interaction with exercise physiology:
Exercise Timing
- Pre-exercise dosing (30-60 minutes before): Research by Reynolds et al. (2021) demonstrated that MOTS-c is naturally released by skeletal muscle during exercise. Pre-exercise administration amplifies the AMPK activation cascade, potentially enhancing the metabolic benefits of your workout — more glucose uptake, more fat oxidation, more mitochondrial biogenesis signals.
- Post-exercise dosing: Some protocols dose immediately after exercise to extend the metabolic window. This approach capitalizes on the post-exercise period when AMPK activity is already elevated.
- Non-exercise days: Morning administration is standard, aligning with the body's natural metabolic rhythms.
Fasting Considerations
No strict fasting is required, but fasted administration may offer advantages: AMPK is more readily activated in a fasted state (when cellular energy stores are lower), potentially enhancing MOTS-c's exercise-mimetic effects. Some protocols specifically combine fasted morning dosing with fasted exercise for maximum AMPK activation.
Cycle Length & Rest Periods
- Standard cycle: 4–8 weeks
- Extended cycle: 8–12 weeks for metabolic/anti-aging protocols
- Rest period: 2–4 weeks between cycles is commonly used, though no strict requirement has been established in published research
- MOTS-c does not appear to cause receptor desensitization in the same way as receptor agonist peptides, since it works through AMPK — a metabolic enzyme — rather than a cell surface receptor
MOTS-c Stacking Options
MOTS-c targets mitochondrial function and metabolic health, making it complementary to several other compounds:
- MOTS-c + NAD+: MOTS-c activates AMPK for mitochondrial biogenesis while NAD+ provides the substrate for sirtuin activation and electron transport. Together they address mitochondrial quantity (more mitochondria) and quality (better-functioning mitochondria).
- MOTS-c + SS-31: MOTS-c signals mitochondrial biogenesis while SS-31 stabilizes the inner mitochondrial membrane. Complementary mitochondrial targets.
- MOTS-c + Epitalon: Addresses different hallmarks of aging — metabolic dysfunction (MOTS-c) and telomere shortening (epitalon).
- MOTS-c + AOD-9604: For body composition — MOTS-c improves glucose uptake and fat oxidation via AMPK while AOD-9604 stimulates lipolysis via GH fragment pathways. Different mechanisms, potentially additive for fat loss.
Always introduce one compound at a time and assess response before adding a second. See the Stack Builder for guided stacking protocols.
Storage
MOTS-c follows standard peptide storage protocols:
- Lyophilized (unreconstituted): -20°C for long-term (years), or 2–8°C (refrigerator) for months
- Reconstituted: Refrigerate at 2–8°C. Use within 28 days
- Protect from direct light and avoid freeze-thaw cycles
- MOTS-c is a 16-amino-acid peptide and follows typical peptide stability patterns
