Carl read the papersWhat it actually is
MOTS-c is a small peptide encoded within mitochondrial DNA. It acts as a metabolic regulator, influencing how cells use energy and respond to stress.
Research interest centres on insulin sensitivity, metabolic health and physical performance — with animal studies showing improved exercise capacity, earning it the ‘exercise mimetic’ nickname.
How it’s thought to work
- AMPK activation — engages a master metabolic energy sensor.
- Insulin sensitivity — reported to improve glucose handling.
- Metabolic flexibility — helps cells switch fuel sources efficiently.
- Exercise-like signalling — mimics some adaptations of physical training in models.
What the research says
Mostly animal and mechanistic, with strong metabolic and longevity interest. Human clinical data is still early.
- Insulin sensitivity and metabolic health.
- Exercise capacity and endurance (animal models).
- Metabolic-aging research.
Reported protocols
These are the doses the peptide community actually reports running (Reddit & forums), alongside published research — logged for education, not as a recommendation to use.
| Parameter | Commonly reported range |
|---|---|
| Community dose | 5 mg/injection (≈7.5–15 mg/week); micro-dose camp runs 0.1–2 mg |
| Frequency | 5 mg 3×/week (MWF “Seeds protocol” — most popular) or 5 mg every 5 days |
| Route | Subcutaneous |
| Cycle | 4–6 weeks; slow (~6 wks to kick in), then taper off |
| Community tip | Injection-site welts are common; SS-31 often run before a MOTS-c cycle |
Common use cases
| Goal | Community protocol notes |
|---|---|
| Metabolic / endurance | 5 mg 3×/wk (MWF), 4–6 wks |
| Insulin sensitivity | before-cardio dosing |
| (Note) | taper off; welts are common |
Mixing it (reconstitution)
Freeze-dried peptides must be reconstituted with bacteriostatic water before they can be measured. Carl’s calculator turns “mg in the vial + ml of water + target dose” into “units on the syringe” — and tells you how long the vial lasts.

Injection & handling
SubQ, 5 mg — the popular ‘Seeds protocol’ is 3×/week (M-W-F) for 4–6 weeks, then weekly. Slow to kick in (~6 weeks). Injection-site welts are common — rotate sites. SS-31 is often run before a cycle. Refrigerate.
Stacks it appears in
- Used alone — MOTS-c is generally studied on its own.
