MOTS-c (or Mitochondrial Open Reading Frame of the 12S rRNA type-c) has sparked interest as a promising peptide in metabolic research, with potential applications ranging from weight management to athletic performance.
Our complete MOTS-c dosage guide provides all the details on dosing protocols, administration techniques, and calculation methods for researchers and healthcare practitioners working with this mitochondrial-derived peptide.
MOTS-c: The Mitochondrial-Derived Peptide
MOTS-c is a 16-amino acid peptide encoded by the mitochondrial 12S rRNA gene that plays a role in energy metabolism regulation. As a mitochondrial-derived peptide (MDP), it is activated in response to stress, exercise, and aging, helping the body maintain metabolic balance and reduce inflammation.
The sequence of MOTS-c (MRWQEMGYIFYPRKLR) is highly conserved among various species, indicating its fundamental biological importance. It functions primarily by activating the AMPK (AMP-activated protein kinase) pathway, a master regulator of cellular energy homeostasis.
With aging, natural MOTS-c levels decline, potentially contributing to insulin resistance, metabolic disorders, and weight gain.
Potential Benefits of MOTS-c
Research suggests MOTS-c may offer several potential benefits:
- Weight reduction and improved metabolic health through increased energy expenditure and fat breakdown1
- Enhanced glucose regulation and insulin sensitivity, particularly in skeletal muscle2
- Improved physical performance and exercise capacity2
- Anti-inflammatory effects through inhibition of MAP kinase pathways1
- Potential anti-aging properties and longevity benefits1

- Duration: 4-6 weeks, followed by once-weekly 5mg for 4 weeks
Protocol Example 6:
- Dosage: 10mg subcutaneously into the abdomen
- Frequency: Once weekly
- Duration: 4 weeks, followed by a second 4-week cycle within a 12-month period

MOTS-c Reconstitution Guide
Proper reconstitution is critical for accurate dosing of MOTS-c peptide.
Reconstitution Procedure
- Start with lyophilized (freeze-dried) MOTS-c powder in a sealed vial
- Use bacteriostatic water for reconstitution (preservative-free sterile water can be used but has a shorter shelf life)
- Standard reconstitution ratio: 1ml of bacteriostatic water per 10mg vial
- For a 5mg vial, use 0.5ml of bacteriostatic water
- Add water slowly, allowing it to trickle down the side of the vial
- Gently swirl to mix; avoid shaking to prevent peptide degradation
Dosage Calculation Formula
The basic formula for calculating the required volume for injection is:
Required volume (mL) = Desired dose (mcg) / Concentration (mcg/mL)
Where:
- Concentration = Total amount of peptide (mcg) / Total volume of solution (mL)
For example:
- If you have 5mg (5000mcg) of MOTS-c reconstituted with 3mL of water
- Concentration = 5000mcg / 3mL = 1666.67mcg/mL
- For a 250mcg dose: Required volume = 250mcg / 1666.67mcg/mL = 0.15mL (15 units on an insulin syringe)

Peptide Reconstitution Calculator
What is the total volume of your syringe?
Select Peptide Vial Quantity
How much bacteriostatic water are you adding?
Concentration: 5.000 mg/mL (5000 mcg/mL)
How much of the Peptide do you want in each dose?
Draw up: 0.010 mL to get 50 mcg
Insulin syringe: 1.0 units (if using a U-100 syringe)
To have a dose of 50 mcg pull the syringe to 5
To accurately calculate your MOTS-c dosage:
- Determine peptide strength: Identify the total amount of MOTS-c in your vial (e.g., 5mg, 10mg)
- Choose reconstitution volume: Decide how much bacteriostatic water to add (typically 1mL per 10mg)
- Calculate concentration: Divide total peptide amount (in mcg) by total solution volume (in mL)
- Determine desired dose: Based on protocol being followed (e.g., 250mcg, 5mg, 10mg)
- Calculate required volume: Divide desired dose by concentration calculated in step 3
Example Calculation
For a 10mg MOTS-c vial reconstituted with 1mL of bacteriostatic water:
- Concentration: 10,000mcg ÷ 1mL = 10,000mcg/mL
- For a 5mg dose: 5,000mcg ÷ 10,000mcg/mL = 0.5mL (50 units on insulin syringe)

Administration Guidelines and Considerations
MOTS-c is administered via subcutaneous injection, meaning it is injected into the fatty tissue just below the skin. It is not effective as an oral supplement due to digestive breakdown.
Common Injection Sites
- Abdomen (at least 1 inch away from navel)
- Thigh
- Upper arm
- Rotate injection sites to prevent irritation
Storage Requirements
- Store lyophilized (unreconstituted) powder at -20°C (-4°F)
- Once reconstituted, store in refrigerator (2-8°C or 36-46°F)
- Avoid repeated freezing and thawing
Safety and Potential Side Effects

While MOTS-c shows promise in research settings, several important safety considerations should be noted:
- Not approved by major regulatory bodies for human use
- Legal status varies by country and jurisdiction
- Banned by major anti-doping agencies for competitive athletes
- Limited human safety data exists
- Potential side effects include injection site reactions, nausea, headache, and fatigue
Who Should Be Cautious?
- Pregnant or nursing individuals
- People with chronic health conditions
- Minors
- Individuals on prescription medications, especially those affecting metabolism, hormones, or blood sugar
The Bottom Line
MOTS-c represents a promising area of peptide research with potential applications in metabolic health, exercise performance, and age-related conditions.
The dosage protocols outlined in this report reflect current research and recommendations, though it’s important to note that optimal dosing may vary between individuals.
For researchers and healthcare practitioners working with MOTS-c, proper reconstitution, accurate dosage calculation, and appropriate administration are essential for safety and efficacy.
As research continues to evolve, these guidelines may be refined to better harness the potential benefits of this mitochondrial-derived peptide.
