MOTS-c
Mitochondrial ORF of the Twelve S rRNA-c · Mitochondrial-Derived Peptide · MOTSc
Think of it as a personal trainer for your cells.
MOTS-c is a tiny protein that comes from the powerhouses of your cells, the mitochondria. It helps your body manage energy better by boosting how your muscles use sugar and fat. Imagine it as a coach that tells your cells to get in shape, especially helpful as you get older.
Research in animals shows it might improve how well you respond to exercise and could help your body stay flexible with its energy use, even when you're not as young as you used to be. Scientists are still figuring out exactly how this works in humans, but the early findings are promising.
Who it's for
- Fitness enthusiasts curious about the next big thing in energy management
- Older adults looking to support healthy aging
- Biohackers interested in cutting-edge longevity research
Probably not for you if…
- People looking for a quick fix without lifestyle changes
- Those uncomfortable with the unknowns of emerging science
- Individuals who prefer well-established supplements with long-term safety data
Editorial summary for research context · Not medical advice
Mechanism of Action
MOTS-c is a 16-amino-acid mitochondrial-derived peptide encoded within the 12S rRNA region of mitochondrial DNA, discovered by the Pinchas Cohen laboratory at USC. Research suggests it acts as a metabolic regulator by activating AMPK signaling, modulating folate/methionine cycle flux, and enhancing glucose uptake and fatty acid oxidation in skeletal muscle. Circulating MOTS-c declines with age and with metabolic disease. Preclinical work in rodents indicates effects on insulin sensitivity, exercise capacity, and age-associated inflammation. Human data is emerging but limited.
Researched Benefits
AMPK activation and metabolic flexibility
Preclinical research suggests activation of AMPK and improved glucose handling in insulin-resistant rodent models.
- [Lee et al. 2015]
Exercise and mitochondrial capacity
Animal models of physical performance showed improved endurance and mitochondrial markers following MOTS-c administration in aged mice.
- [Reynolds et al. 2021]
Age-associated metabolic decline
Circulating levels decline with age; restoration in preclinical models reduces age-associated metabolic decline markers.

Research Protocols
The following dosing ranges have appeared in published research protocols. Presented for informational purposes only — not a recommendation for human use.
Metabolic research protocol
- Dosage
- 10 mg
- Frequency
- 3x weekly
- Timing
- morning
- Cycle
- 8 weeks
Research protocols commonly use 5-10 mg subcutaneously, 3 times per week. Morning administration aligned with activity periods in rodent models.
Lower-dose daily research
- Dosage
- 5 mg
- Frequency
- daily
- Timing
- morning
- Cycle
- 4 weeks
Daily low-dose protocol used in shorter research cycles focused on insulin sensitivity endpoints.
Reported Side Effects
- Injection-site irritation
- Transient hypoglycemia-like symptoms if combined with fasting or heavy training
- Long-term human safety data is limited
Contraindications
- Pregnancy and lactation
- Type 1 diabetes (caution due to glucose-handling effects)
- Concurrent high-dose hypoglycemic therapy without supervision
