MOTS-c (Mitochondrial ORF of the 12S rRNA Type-c) is a 13-amino acid peptide encoded by mitochondrial DNA. It is being studied for its role in:
- Metabolic regulation
- Cellular stress resistance
- Insulin sensitivity
- Exercise adaptation
- Aging and mitochondrial function
It interacts with the AMPK pathway, among others, making it of interest in research on obesity, diabetes, and muscle metabolism.
🧪 Research Use Only (RUO) Context
MOTS-c is classified as RUO (Research Use Only). It is not approved for human use by the FDA or any major regulatory body. Any use outside of a licensed research facility with appropriate oversight is:
- Unregulated
- Potentially unsafe
- Legally risky
📊 Preclinical Research Dosing (Rodent Models)
In published studies, MOTS-c has been administered to mice using the following parameters:
| Study Model | Route | Dose | Frequency | Duration |
|---|---|---|---|---|
| Metabolic studies (e.g., obesity, insulin resistance) | Intraperitoneal (IP) injection | ~5 mg/kg | Daily | 2–4 weeks |
| Aging & mitochondrial stress | IP | 5–15 mg/kg | 3–7x/week | 4–8 weeks |
⚠️ These values are species-specific and cannot be directly translated to human use. The common practice of converting mouse doses to human equivalents (HED) using body surface area is not valid for untested peptides.
💡 Key Considerations for Research Planning
If you’re working in a research setting:
- Sterile technique and proper peptide reconstitution are essential (typically with sterile water or dilute acetic acid, depending on purity and form).
- The peptide must be stored cold (-20°C or below) and protected from light.
- Experiment design should include baseline metabolic markers (e.g., glucose, insulin, AMPK phosphorylation) and clear endpoints (muscle mass, endurance, gene expression).
🚫 Not Approved for Human Use
Using MOTS-c in humans could result in:
- Unpredictable metabolic effects
- Immune response risks
- No reliable data on long-term safety
No clinical trials to date have defined safe or effective human doses. If any are underway, they are under strict Institutional Review Board (IRB) oversight.
✅ Safer Alternatives for Exercise or Metabolic Support
If your goal is muscle performance or metabolic health, consider:
- Creatine monohydrate
- Beta-alanine
- Citrulline malate
- Clinically supported endurance supplements
These have human data, FDA oversight (where applicable), and are legal for over-the-counter use.
