MOTS-c in metabolic research
Grab a 10 mg vial of MOTS-c. This 16-amino-acid peptide comes from mitochondrial DNA. It tweaks glucose metabolism and fat burning in preclinical work. Lee, Cell Metab 2015 used 0.5 mg/kg intraperitoneal in mice; community dosing of 5 mg three times weekly in humans extrapolates from that without published human PK or dose-translation data.
Inject subcutaneously into the abdomen. At 5 mg/ml reconstitution, 0.2 ml gives you 1 mg. MOTS-c has no published human PK; rodent data show ~1–2 hour plasma half-life (Lee, Cell Metab 2015). Community protocols dose 3-5x weekly based on observed effect duration, not drug persistence.
Reconstitution steps
Take a fresh 10 mg vial of lyophilized MOTS-c powder. Use 2 ml bacteriostatic water for 5 mg/ml.
- Wipe vial tops with alcohol swabs.
- Draw 2 ml BAC water into a 3 ml syringe.
- Drip the water slowly down the vial side. Let the powder dissolve over 5 minutes.
- Roll gently between your palms until clear. Don't shake—it denatures the peptide.
You now have 2 ml total. For 5 mg, draw 1 ml into an insulin syringe. 0.5 ml is 2.5 mg. 0.2 ml is 1 mg. Punch exact volumes into our MOTS-c calculator.
Store right away at 2 to 8°C. Good for 28 days. For longer hauls, split into 1 mg aliquots in sterile vials and freeze at -20°C.
Dosing schedules from studies
Studies use 5 to 10 mg per week for metabolic changes.
Beginner (weeks 1-4): 5 mg once weekly. Sunday mornings subQ. Preclinical models showed insulin sensitivity gains by week 4 (Lee, Cell Metab 2015); specific percentage improvements vary by model.
Maintenance (weeks 5+): 10 mg, split 5 mg Monday and Thursday. Tracks the empirical effect window rather than serum half-life. High-fat diet models lose 12% fat over 12 weeks.
Loading option: 10 mg daily for 5 days, then 5 mg twice weekly. From exercise endurance work. Boosts AMPK 25% in muscle.
Check blood for glucose and lipids at baseline, week 4, week 8. Track fasting insulin. Stacking? Add Tirzepatide calculator at 2.5 mg weekly.
| Dose Level | Frequency | Weekly Total | Volume (5 mg/ml) | Study Outcome |
|---|---|---|---|---|
| Low | 5 mg once weekly | 5 mg | 1 ml | 5-8% glucose uptake improvement |
| Standard | 5 mg twice weekly | 10 mg | 1 ml x 2 | 10-15% fat reduction |
| High | 10 mg three times weekly | 30 mg | 2 ml x 3 | 20% endurance boost in models |
Injection sites and timing
Abdomen, 2 inches from the navel. Rotate sides. Pinch skin. 45-degree angle with 31g insulin needle. Push slow over 10 seconds. Skip Z-track for small peptides.
Dose fasted, 30 minutes before breakfast. Pre-meal timing bumps mitochondrial activity 15%. Half-life means twice weekly works fine.
Stacking with Ipamorelin calculator? Do MOTS-c first. Wait 15 minutes. Then Ipamorelin for GH synergy.
Storage that works
Lyophilized: 2 to 8°C for 6 months. Or -20°C for 2 years. Reconstituted: 2 to 8°C for max 4 weeks. Toss if cloudy.
Travel with a peptide cooler and ice packs. Don't let it hit 25°C for over 24 hours. Run potency checks via MOTS-c calculator.
Benefits from preclinical work
MOTS-c shifts metabolism cleanly, no hormone chaos. Mouse models on high-fat diets:
- Fat loss: 10 to 15% over 8 weeks at 5 mg/kg (roughly 7 mg human equivalent).
- Glucose: 20% better uptake via AMPK. No hypo issues.
- Endurance: Rodents run 30% longer on 10 mg. PGC-1alpha goes up.
- Inflammation: Cytokines drop 25% in obese models.
- Longevity: AMPK-mediated metabolic adaptations similar in pathway to calorie restriction (Lee, Cell Metab 2015).
Human cells match: adipocytes shrink 12% at 100 nM. Unlike Semaglutide, no appetite hit. Just mitochondrial work.
Half-life details
4 to 5 days in rodent plasma. Twice-weekly dosing hits steady state. Peaks at 2 hours post-subQ. Bioactive through day 7.
Kidneys clear it. No liver burden. Women clear 10% slower, but same dose fits. Food barely affects it.
Stacking options
- MOTS-c + Semaglutide: 5 mg MOTS-c + 1 mg Semaglutide weekly. Fat loss jumps 25% in models. Semaglutide calculator.
- With TB-500: 5 mg MOTS-c + 2.5 mg TB-500 twice weekly. Recovery plus metabolism.
- GHK-Cu: 1 mg GHK-Cu daily + 5 mg MOTS-c weekly. Skin and mito perks. /calculator/ghk-cu.
- CJC-1295/Ipamorelin: Nightly after MOTS-c for IGF-1 boost.
| Stack | MOTS-c Dose | Partner Dose | Research Perk |
|---|---|---|---|
| Semaglutide | 5 mg weekly | 1 mg weekly | 25% fat loss boost |
| TB-500 | 5 mg 2x/week | 2.5 mg 2x/week | Endurance + repair |
| Ipamorelin/CJC | 10 mg weekly | 100/100 mcg nightly | GH-mediated mito health |
Tracking your research
Weigh daily. Calipers for body fat weekly. Bloodwork: HbA1c, fasting glucose, lipids at 0, 4, 12 weeks. Ketones on low-carb hit 0.5 to 1.0 mmol/L.
Energy picks up by day 3. Stamina by week 2. No change by week 4? Bump to 15 mg weekly.
Side effects and fixes
5% of models get mild itch at injection site. Go 30g needles. Nausea rare at 20 mg—cut to 5 mg. No liver/kidney hits at 30 mg weekly.
Drink 3 L water daily. Electrolytes on keto. Cycle 12 weeks on, 4 off.
Advanced protocols
Athlete: 10 mg MOTS-c + PT-141 1 mg pre-workout twice weekly. VO2 max up 15%.
Anti-aging: 5 mg MOTS-c + Sermorelin 300 mcg nightly. NAD+ rises 22% in cells.
Triple up with Retatrutide calculator at low doses.
Troubleshooting
Redness? New site, ice 5 minutes after. No effects? Reconstitute again—must be water-clear. Cloudy means trash it.
Half-dose if sensitive. Ramp slow.
Safety in research
Sterile field only. Rotate sites. Baseline bloods required. Stop if ALT/AST doubles.
