MOTS-c Dosage Calculator: Optimize Your Metabolism and Cellular Energy

What is MOTS-c and How Does It Work?

MOTS-c (Mitochondrial Open Reading Frame of the 12S rRNA type-c) is a 16-amino acid peptide encoded by mitochondrial DNA rather than nuclear DNA. This makes it part of a unique class called mitochondrial-derived peptides (MDPs).

Your body naturally produces MOTS-c in response to exercise, fasting, and metabolic stress. It acts as a metabolic regulator, helping your cells adapt to energy demands and maintain metabolic balance.

How MOTS-c works: The peptide primarily activates AMPK (adenosine monophosphate-activated protein kinase), often called the body's "master metabolic switch." When AMPK is activated, it triggers a cascade of beneficial effects including improved glucose uptake, enhanced fat oxidation, and increased mitochondrial function.

What makes MOTS-c unique:

• Encoded by mitochondrial DNA (not nuclear DNA like most peptides)
• Acts as an "exercise mimetic" that simulates some benefits of physical activity
• Naturally increases during exercise and fasting
• Targets metabolic pathways at the cellular level
• Declines with age, potentially contributing to metabolic dysfunction

MOTS-c Benefits and Research Applications

MOTS-c has been studied for multiple metabolic and age-related applications:

MOTS-c Dosage Protocols

Dosing varies based on protocol type and treatment goals. There are two main approaches: intermittent dosing (every few days) and daily microdosing.

Intermittent Dosing Protocols (Most Common)

Daily Microdosing Protocol (Alternative Approach)

Some protocols use smaller daily doses with gradual titration:

How to Calculate Your MOTS-c Dose

Calculating your dose requires understanding the relationship between vial concentration, syringe units, and your target mg dose.

Step 1: Determine Your Vial Concentration

After reconstitution, your concentration depends on how much bacteriostatic water you add:

Step 2: Calculate Units on Your Syringe

Using a standard U-100 insulin syringe (100 units = 1 ml):

Formula: Units to draw = (Desired dose in mg / Concentration in mg/ml) x 100

Example calculations for 10 mg vial reconstituted with 1 ml (10 mg/ml):

Reconstitution: Mixing Your MOTS-c Properly

Proper reconstitution is especially critical for MOTS-c due to its instability. The peptide degrades rapidly once mixed.

What You Need

• MOTS-c lyophilized powder vial
• Bacteriostatic water (not sterile water or saline)
• Sterile syringes (one for mixing, separate ones for injections)
• Alcohol swabs
• Clean, flat work surface

Reconstitution Process

1. Prepare your workspace: Clean your surface and wash your hands thoroughly. Gather all supplies before starting.

2. Clean the vial tops: Wipe the rubber stoppers of both the MOTS-c vial and bacteriostatic water with alcohol swabs. Allow to air dry.

3. Draw the bacteriostatic water: Using a sterile syringe, draw your calculated amount of bacteriostatic water.

4. Add water to the MOTS-c vial: Insert the needle at an angle, aiming the stream at the glass wall rather than directly onto the powder. Add water slowly.

5. Allow to dissolve: Let the vial sit for 1-2 minutes. Gently swirl or roll the vial between your palms. Never shake vigorously as this can cause foaming and damage the peptide.

6. Inspect the solution: The reconstituted MOTS-c should be clear and colorless. Do not use if cloudy, discolored, or containing visible particles.

Critical Storage Information

MOTS-c is highly unstable compared to other peptides. Proper storage is essential:

• Lyophilized (powder): Store frozen at -4°F (-20°C) or below. Stable for up to 3 years frozen, 2 years refrigerated.
• Reconstituted: Refrigerate at 36-46°F (2-8°C) immediately. Use within 7 days for best potency.
• Room temperature warning: MOTS-c loses approximately 25% activity after just 24 hours at refrigerator temperature, and 85-90% activity after 2-3 hours at room temperature.
• Light sensitive: Protect from light at all times.
• Aliquoting option: For longer storage, prepare single-use aliquots and freeze at -4°F (-20°C). Avoid repeated freeze-thaw cycles.

Administration Protocol

Timing Your Injection

Optimal timing: Morning administration is preferred, ideally before exercise or fasted cardio. This aligns with MOTS-c's natural production patterns during fasting and physical activity.

Timing guidelines:

• Inject in the morning on an empty stomach when possible
• 30-60 minutes before fasted cardio enhances effects
• On non-training days, morning injection still recommended
• Maintain consistent timing for best results

Injection Technique

MOTS-c is administered via subcutaneous injection into the fatty tissue just beneath the skin.

Preferred injection sites:

• Abdomen (2 inches away from navel)
• Front or outer thigh
• Back of upper arm

Site rotation: Rotate injection sites with each dose to prevent tissue irritation and lipohypertrophy. This is especially important with MOTS-c due to potential injection site reactions.

Schedule Options

Standard 20-Day Protocol:

• 5 mg every 5 days for 20 days (4 injections total)
• Repeat cycle 2-4 times per year

Extended 30-Day Protocol:

• 10 mg once weekly for 4 weeks
• Repeat within 6 months

Intensive Protocol:

• 5 mg three times weekly for 4-6 weeks
• Use for more aggressive metabolic goals

Factors That Affect Your Response

Lifestyle Synergies

Exercise: MOTS-c is considered an "exercise mimetic" and works synergistically with physical activity. Combining MOTS-c with regular exercise amplifies benefits.

Fasting: Intermittent fasting or caloric restriction may synergize with MOTS-c's AMPK-mediated effects, as both activate similar metabolic pathways.

Diet: A protein-adequate, nutrient-dense diet supports the metabolic improvements MOTS-c provides.

Individual Factors

Age: MOTS-c levels naturally decline with age. Older individuals may experience more pronounced benefits from supplementation.

Baseline metabolic health: Those with metabolic dysfunction (obesity, insulin resistance) may see greater improvements than metabolically healthy individuals.

Activity level: Active individuals may synergize better with MOTS-c's exercise-mimetic effects.

MOTS-c Stacking Options

MOTS-c can be combined with other peptides for enhanced effects. Always consult with a healthcare provider before combining therapies.
