MOTS-C (40mg Vial) Dosage Protocol
MOTS-c is a 16-amino-acid mitochondrial-derived peptide that helps regulate metabolic homeostasis, mainly by activating the AMPK energy-sensing pathway. In preclinical work it is described as an "exercise-mimetic" supporting insulin sensitivity, glucose handling and fat oxidation. It is referenced as a once-daily subcutaneous injection dosed in micrograms with gradual titration. There are no completed human efficacy trials of MOTS-c; presented for research and educational purposes only.
Mitochondrial-derived peptide; preclinically activates AMPK and supports insulin sensitivity, glucose handling and fat oxidation. No completed human efficacy trials.
Once-daily subcutaneous injection, titrated from ~200 mcg to ~1,000 mcg/day over roughly 10 weeks.
3 mL bacteriostatic water per 40 mg vial gives ~13.33 mg/mL, so 1 unit is about 133.3 mcg on a U-100 syringe.
Freeze the lyophilized vial; refrigerate the reconstituted solution, do not freeze it, and use within about 7 days.

Dosing & Reconstitution Guide
A single practical dilution with accurate once-daily dosing, step by step
Standard / Gradual Approach (3 mL = ~13.33 mg/mL)
Reconstitute: Add 3.0 mL bacteriostatic water to one 40 mg vial → final concentration ~13.33 mg/mL (13,333 mcg/mL).
Typical daily range: 200–1,000 mcg once daily, raised gradually over an ~10-week course.
Measuring: At ~13.33 mg/mL, 1 unit ≈ 133.3 mcg on a U-100 syringe, so the ladder runs 1.5–7.5 units. The 200 mcg starting step is only ~1.5 units — half-unit territory, where syringe resolution rather than the peptide is the limiting factor. Arithmetically, filling the same vial with 4.0 mL instead (10 mg/mL) would make 100 mcg exactly 1 unit and shift the ladder to 2–10 units, if the vial accepts that volume.
Storage: Lyophilized: store at −20 °C (−4 °F); after reconstitution, refrigerate at 2–8 °C (35.6–46.4 °F), do not freeze the mixed solution, and use within about 7 days.

Quickstart Highlights
MOTS-c is a 16-amino-acid mitochondrial-derived peptide (a short peptide encoded within mitochondrial DNA) that helps regulate metabolic homeostasis, mainly by activating the AMPK energy-sensing pathway[1][2]. In preclinical work it has been described as an “exercise-mimetic,” supporting insulin sensitivity, glucose handling and fat oxidation. This educational page outlines a once-daily subcutaneous approach with a dilution chosen so doses land on easy-to-read insulin-syringe marks. It is an unapproved research chemical, not a medicine, and there are no completed human efficacy trials — presented for research and educational use only.
Add 3.0 mL bacteriostatic water to one 40 mg vial → ~13.33 mg/mL (13,333 mcg/mL), the same 3.0 mL fill used across the other MOTS-C vial sizes.
200–1,000 mcg once daily, titrated upward gradually over an ~10-week course in roughly 200 mcg steps.
At ~13.33 mg/mL, 1 unit ≈ 133.3 mcg; 200 mcg ≈ 1.5 units and 1,000 mcg ≈ 7.5 units on a U-100 syringe.
Lyophilized: store at −20 °C (−4 °F); once reconstituted, refrigerate at 2–8 °C (35.6–46.4 °F), do not freeze the solution, and use within about 7 days.
Important: Start with the Prep & Injection Guide — it covers the preparation and safety basics every protocol on this site assumes.
Frequency: one subcutaneous injection each day, holding each dose level for about two weeks before stepping up as tolerated[7]. These figures come from commonly cited reference protocols and animal-to-human extrapolation, not from approved human dosing.
Reconstitution Steps
Draw 3.0 mL of bacteriostatic water into a sterile syringe.
Release it slowly down the vial’s inner wall to limit foaming.
Swirl or roll gently until fully dissolved — don’t shake.
Label with the date and concentration, then refrigerate at 2–8 °C (35.6–46.4 °F), shielded from light.
The 3.0 mL dilution is deliberately large so each dose reads at several units or more, where U-100 syringe markings are most precise. Avoid freezing the reconstituted solution, since freeze–thaw can denature the peptide.
Supplies Needed
Quantities below assume an 8–16 week course of once-daily injections with gradual titration.
A single 40 mg vial covers roughly eight weeks at the lower titration doses, so plan vials to your cycle length and target dose.
- 8 weeks: ~1 vial
- 12 weeks: ~2 vials
- 16 weeks: ~3 vials
- Per injection: 1 syringe
- 8 weeks (once daily): ~56 syringes

- 8 weeks (3 vials): ~9 mL → 1 bottle
- 16 weeks (9 vials): ~27 mL → 3 bottles
One for the vial stopper + one for the injection site each day.
- Per injection: 2 swabs
- 8 weeks (once daily): ~112 swabs → 1–2 boxes
Protocol Overview
A concise summary of the once-daily regimen, drawn from commonly cited reference protocols.
- ▪Goal: Support metabolic homeostasis, insulin sensitivity and age-related physical performance — effects reported preclinically, not established in humans[1][4].
- ▪Schedule: Daily subcutaneous injections for 8–12 weeks, optionally extended to ~16 weeks for longer research goals.
- ▪Dose Range: 200–1,000 mcg per day with gradual titration over roughly 10 weeks.
- ▪Reconstitution: 3.0 mL bacteriostatic water per 40 mg vial gives ~13.33 mg/mL, so 1 unit is about 133.3 mcg.
- ▪Storage: Keep the dry vial frozen at −20 °C (−4 °F); once mixed, refrigerate at 2–8 °C and do not freeze the solution.
Dosing Protocol
A suggested daily titration approach based on common reference doses and animal-to-human extrapolation.
- ▪Start: Begin at 200 mcg once daily for two weeks to gauge tolerability.
- ▪Titrate: Increase by roughly 200 mcg every two weeks as tolerated (400 → 600 → 800 mcg).
- ▪Target: Reach up to about 1,000 mcg (1.0 mg) daily by weeks 9–10+ if well tolerated.
- ▪Cycle Length: Typically 8–12 weeks; some references extend to ~16 weeks.
- ▪Timing: Inject at a consistent time each day and rotate injection sites systematically.
Storage Instructions
Correct storage is what preserves the peptide’s stability and activity.
- ▪Lyophilized: Hold the dry vial at −20 °C (−4 °F) in dry, dark conditions and limit moisture exposure[9].
- ▪Reconstituted: Refrigerate at 2–8 °C (35.6–46.4 °F) and use within about 7 days for best potency; do not freeze the mixed solution, as freezing can denature peptides[11].
- ▪Handling: Let frozen vials warm to room temperature before opening so condensation won’t form, and keep the solution clear of heat and direct light.
- ▪Freeze–thaw: Prepare single-use aliquots if needed and avoid repeated freeze–thaw cycles of the reconstituted solution.
Important Notes
Practical points that keep daily administration safe and consistent.
- ▪Sterile technique: Use a fresh sterile U-100 insulin syringe each time and drop it straight into a puncture-proof sharps container afterward.
- ▪Site rotation: Move between abdomen, thighs and upper arms to reduce local irritation and lipohypertrophy[11].
- ▪Slow injection: Push the plunger slowly and pause a few seconds before withdrawing the needle to prevent backflow.
- ▪Recordkeeping: Log the daily dose, injection site and any observations to keep the protocol consistent.
- ▪Regulatory note: MOTS-c is not FDA-approved for human administration and is an unapproved research chemical; discontinue and consult a professional if any concerning symptoms arise[8].
How This Works
MOTS-c is a 16-amino-acid mitochondrial-derived peptide (MDP) — a short peptide encoded within a region of mitochondrial DNA rather than the cell nucleus. It behaves like a metabolic “stress signal” that helps cells optimize energy use during nutrient stress or exercise[2].
Its core proposed mechanism is activation of the AMPK energy-sensing pathway. In preclinical work, MOTS-c is described as interfering with the folate cycle, leading to a build-up of AICAR (an AMP analog) that switches on AMPK[1][2]. Activated AMPK shifts cells toward an energy-efficient state — supporting glucose uptake, fatty-acid oxidation and mitochondrial respiration while dialing down fat storage and gluconeogenesis.
Under stress, MOTS-c has also been reported to move into the cell nucleus and help turn on antioxidant and stress-response genes — a form of retrograde signalling from the mitochondria to the nucleus[2]. Because these effects echo what happens with exercise and with metformin at a cellular level, MOTS-c is often referred to as an “exercise-mimetic”[4].
Important caveat: the evidence for these mechanisms and benefits is preclinical — based on cell and animal studies. There are no completed human efficacy trials of MOTS-c; the closest human data involve a modified analog (CB4211) studied for tolerability[7][8]. Metabolic, performance and longevity claims should be read as hypotheses, not established outcomes.
MOTS-c is not an approved medicine. It is an unapproved research chemical presented here for research and educational purposes only.
Lifestyle Factors
Habits that may complement the protocol, given MOTS-c’s metabolic mechanisms.
- ▪Nutrition: Pair with a balanced, protein-forward diet tailored to your energy needs.
- ▪Activity: Combine resistance training and aerobic activity to reinforce metabolic adaptations and AMPK signalling[4].
- ▪Sleep: Aim for 7–9 hours to support mitochondrial health and recovery.
- ▪Fasting: Intermittent fasting or modest caloric restriction may overlap with MOTS-c’s AMPK-mediated effects.
Potential Benefits & Side Effects
What preclinical literature describes; human evidence is absent and individual results are unknown.
Potential Benefits
- ▪Metabolic health (preclinical): In mouse models, MOTS-c improved insulin sensitivity and glucose handling and helped prevent diet-induced insulin resistance[1].
- ▪Fat & weight (preclinical): Reduced visceral fat and helped prevent obesity in mice via increased energy expenditure and fat oxidation[1].
- ▪Physical performance (preclinical): Described as an exercise-mimetic that enhanced exercise capacity and countered age-related decline in animal studies[4].
- ▪Note on humans: These benefits are not established in humans — no completed human efficacy trials of MOTS-c exist[8].
Common Side Effects
- ▪Injection-site reactions: Mild redness, tenderness or soreness can occur; rotating sites helps.
- ▪Unknown human profile: No human safety data exists for MOTS-c, so caution and monitoring are advised.
- ▪Research status: MOTS-c is an unapproved research chemical and is not intended for human use.
Injection Technique
General subcutaneous technique, following established clinical best-practice guidance[9][11].
Pre-Injection Preparation
- ▪Wash your hands well with soap and water.
- ▪Wipe the vial stopper with an alcohol swab and let it air-dry.
- ▪Choose a site (abdomen, thigh, or upper arm) and clean it with a fresh alcohol swab, letting it dry fully[11].
- ▪Draw the intended dose, then check for air bubbles and push any out.
Injection Procedure
- ▪Pinch a skinfold at the chosen site between thumb and forefinger.
- ▪Insert the needle into the pinch at a 45–90-degree angle (use 45 degrees if the fat layer is thin)[9].
- ▪Skip aspiration for subcutaneous shots — it isn’t needed[9].
- ▪Press the plunger slowly and steadily until it’s fully down.
- ▪Wait 5–10 seconds, then pull the needle straight out to prevent leakage.
Post-Injection Care
- ▪Drop the used syringe straight into a puncture-proof sharps container — never recap a needle.
- ▪Return the reconstituted vial to the fridge right away.
- ▪Rotate the injection site each day to prevent irritation and lipohypertrophy[11].
- ▪Watch the site for excess redness, swelling, or signs of infection.

MOTS-C — frequently asked questions
How do I reconstitute a 40 mg vial of MOTS-C?
Wipe the stopper with an alcohol swab, then inject your bacteriostatic water slowly down the inside wall of the vial. Let it sit and gently swirl until dissolved — never shake. Store the mixed vial in the refrigerator and draw doses with an insulin syringe. Use the calculator above to turn any dose into syringe units.
How much bacteriostatic water should I add to MOTS-C?
There is no single correct amount — more water simply spreads the same 40 mg of peptide across a larger volume, which makes small doses easier to measure accurately. 1 to 3 mL per vial is typical. Enter your chosen volume in the calculator above to see the resulting concentration and syringe units.
What do the "units" on an insulin syringe mean?
On a U-100 insulin syringe, 100 units equal 1 mL, so 1 unit equals 0.01 mL. The calculator above converts your draw volume into these units automatically so you can measure without doing the math by hand.
How should I store MOTS-C after mixing?
Keep the reconstituted vial refrigerated at roughly 2 to 8 degrees Celsius, away from light, and avoid freezing it. Reconstituted research peptides are generally used within a few weeks. Always follow the specific guidance supplied with your product.
How many doses does a 40 mg vial of MOTS-C provide?
Divide the vial strength of 40 mg by the amount you use per injection. The calculator above reports this as "doses per vial" the moment you enter a dose.
Is MOTS-C approved for human use?
No. MOTS-C is sold strictly for laboratory and research purposes and is not approved by the FDA or other regulators for human use. Everything on this page is research information, not medical advice — consult a licensed healthcare professional before any use.
