MOTS-c (Mitochondrial Open Reading Frame of the 12S rRNA-c)
A mitochondria-derived peptide that acts as an exercise mimetic, improving metabolic homeostasis, insulin sensitivity, and fat oxidation. Levels decline significantly with age.
How it works
Activates AMPK pathway, enhances mitochondrial metabolism, improves insulin sensitivity by increasing GLUT4 translocation, and promotes fatty acid oxidation.
Key facts
- Molecular weight: 2,175 Da
- Half-life: 4-8 hours
- Bioavailability: Moderate (SubQ)
- Storage: Lyophilized: -20°C. Reconstituted: 2-8°C for 14 days.
Dosing overview
- Typical dose: 5-10 mg

- Duration: 8-12 weeks
- Route: Subcutaneous injection
Protocol notes
- Most run 5-10 mg per dose, 3-5x weekly (not usually daily).
- Many time doses around training to leverage the AMPK/metabolic effect.
Reported benefits
- Exercise mimetic effects
- Improved insulin sensitivity
- Enhanced fat oxidation
- Metabolic homeostasis
- Anti-aging metabolic benefits
- AMPK activation
Possible side effects
- Injection site reactions
- Mild hypoglycemia (with exercise)

Research
- MOTS-c as exercise mimetic and metabolic regulator (2022): MOTS-c in aged mice improved exercise capacity by 35% and restored insulin sensitivity to youthful levels.
- Decline of circulating MOTS-c with aging (2021): Plasma MOTS-c decreased by 50% between ages 20-60, correlating with declining metabolic health.
Community reviews of MOTS-c
- injection_journal rated it 5/5 - Worth adding to the protocol: MOTS-c has been a worthwhile addition. I am data-driven and tracked relevant markers before, during, and after. The improvement is measurable and correlates with the intervention timeline. What sets this apart from some compounds I have tried is the consistency. Benefits did not fluctuate wildly or disappear. They built up and maintained. That gives me confidence in the mechanism. Tolerance has been excellent. Nothing in my bloodwork or subjective experience raised any flags. This is the kind of compound that does its job quietly without causing problems. Exactly what you want.
- syringe_science_sue rated it 5/5 - Solid compound with real results: Been using MOTS-c for about 2 months and the results are clear. Not overnight dramatic, but a steady, consistent improvement that became undeniable by the end of the first month. The mechanism makes sense based on what I have read in the literature, and my subjective experience matches the expected timeline. Benefits built gradually and plateaued at a good level. Side effects were minimal to none at the dose I used. Followed proper protocols for sourcing, storage, and administration. Would recommend to others who have done their research and have realistic expectations.
- deep_science_dee rated it 5/5 - Genuinely effective after 3 weeks: Been using MOTS-c for about 3 weeks and the results are clear. Not overnight dramatic, but a steady, consistent improvement that became undeniable by the end of the first month. The mechanism makes sense based on what I have read in the literature, and my subjective experience matches the expected timeline. Benefits built gradually and plateaued at a good level. Side effects were minimal to none at the dose I used. Followed proper protocols for sourcing, storage, and administration. Would recommend to others who have done their research and have realistic expectations.
- biohack_bree rated it 5/5 - Noticed clear benefits within weeks: Added MOTS-c to my protocol about 6 weeks ago and it has earned its place. The benefits became noticeable around week 2-3 and have been consistent since. What I appreciate about this compound is the predictability. It does what the research suggests it should do, at roughly the timeline you would expect. No surprises, no dramatic swings, just steady improvement. No notable side effects to report at my dose. Sourcing is always the challenge with research compounds, insist on third-party testing. Storage and reconstitution per standard protocols. Plan to continue.
- kyle_k rated it 4/5 - helped me lean out, but i liked cjc/ipa more: i ran mots-c for about 4 months while i was juggling startup work, lifting, and trying to keep my weight in check in the midwest winter, and i dropped about 18 lbs over that stretch. for me it seemed to make cutting feel smoother, especially around cardio and stubborn fat, but the effect felt a little subtle. i honestly preferred cjc/ipa for overall body comp, that one felt more noticeable to me, though mots-c still earned a solid 4 stars.
- optimized_macros rated it 4/5 - MOTS-c helped my cut, but it was subtle: I ran MOTS-c for about 6 weeks while I was juggling coaching, my own training, and trying to trim a bit of fluff here in Aus. For me, it seemed to make fasted sessions feel a touch easier and I was a bit better at staying on plan without feeling flat all arvo. The scale moved, but not in some dramatic way, more like the cut just behaved itself better. That’s why I’m at 4 stars. The caveat, it’s subtle. Could be some placebo in there too.
