MOTS-c Reconstitution & Dosage Calculator
This free MOTS-c calculator turns your vial size, the bacteriostatic water you add, and your target amount into a concentration, a draw volume, and the exact units on a U-100 insulin syringe. MOTS-c amounts can range from small mcg entries to larger mg draws — the calculator handles either.
Quick summary
- Converts vial size (mg), bacteriostatic water (mL), and a milligram or microgram amount into concentration, draw volume, and U-100 units.
- Built for MOTS-c, with reference math for the common 10 mg research vial.
- Educational measurement tool only — it does not diagnose, treat, or recommend an amount.

What this MOTS-c calculator does
This calculator does one job well: it turns your vial size, the amount of bacteriostatic water you add, and your target amount into a concentration (mg/mL), a draw volume (mL), and the matching units on a U-100 insulin syringe. Change any input and the result updates instantly.
MOTS-c ships as a freeze-dried powder. Before it can be measured into a syringe it has to be reconstituted — dissolved in bacteriostatic water. How much water you add sets the concentration, and the concentration sets how many units each amount works out to. The presets above cover the most common MOTS-c vial setups; use the custom fields for anything else.
How to use the MOTS-c calculator
Pick your syringe
Choose the U-100 insulin syringe you'll draw with. Smaller syringes (0.3 mL / 30u) have finer lines, which helps when the draw is small.
Enter your vial and water
Set the milligrams in your MOTS-c vial and the bacteriostatic water you added. Together these set the concentration.
Set your target amount
Toggle mg or mcg and pick (or type) the amount you're measuring for. The calculator does the conversion for you.
Read the draw
The result panel shows concentration, draw volume, and the exact U-100 units to pull, plus how many doses your vial contains.
MOTS-c reconstitution math, explained
The math is short. Concentration = vial size ÷ bacteriostatic water. Draw volume = target amount ÷ concentration. Units = draw volume × 100 (a U-100 syringe reads 100 units per mL). The table below shows common MOTS-c setups and the units for a 1 mg amount at each.
| Vial size | Bac water | Concentration | Units per 1 mg |
|---|---|---|---|
| 5 mg | 1.0 mL | 5 mg/mL | 20 units |
| 10 mg | 1.0 mL | 10 mg/mL | 10 units |
| 10 mg | 2.0 mL | 5 mg/mL | 20 units |
| 10 mg | 2.5 mL | 4 mg/mL | 25 units |
| 10 mg | 3.0 mL | 3.33 mg/mL | 30 units |
MOTS-c amount-to-units reference
How common amounts convert to U-100 syringe units at two example concentrations. These are arithmetic conversions for reference, not a recommendation of any amount.
| Amount | Volume (mL) | U-100 units |
|---|---|---|
| 2.5 mg (2500 mcg) | 0.25 mL | 25 units |
| 5 mg (5000 mcg) | 0.5 mL | 50 units |
| 7.5 mg (7500 mcg) | 0.75 mL | 75 units |
| 10 mg (10000 mcg) | 1 mL | 100 units |
| Amount | Volume (mL) | U-100 units |
|---|---|---|
| 2.5 mg (2500 mcg) | 0.5 mL | 50 units |
| 5 mg (5000 mcg) | 1 mL | 100 units |
| 7.5 mg (7500 mcg) | 1.5 mL | 150 units |
| 10 mg (10000 mcg) | 2 mL | 200 units |
Mixing, color & storage tips
A clear solution
MOTS-c reconstitutes to a clear, colorless liquid. Discard the vial if it is cloudy, discolored, or has particles.
Larger draws with dilute mixes
At 5 mg/mL, a full-milligram amount can approach or exceed a 1 mL syringe. A higher concentration (10 mg/mL) halves the draw — the calculator flags anything over your syringe.
mg vs mcg
MOTS-c can be entered in either unit — 1 mg = 1000 mcg. Toggle the unit to match your reference.
Storage
Refrigerate the reconstituted vial and keep it dark; use within a limited window. Keep the dry powder cold for longer storage and do not freeze a mixed vial.

MOTS-c — frequently asked questions
What does this MOTS-c calculator tell me?
It converts your vial size, bacteriostatic water volume, and target amount into concentration (mg/mL), draw volume (mL), and U-100 syringe units.
Is the MOTS-c reconstitution calculator free?
Yes — free, browser-based, no account.
How much bacteriostatic water for a 10 mg MOTS-c vial?
A 10 mg vial with 1 mL makes 10 mg/mL; with 2 mL it makes 5 mg/mL. A higher concentration keeps larger milligram amounts within one syringe.
How many units is 5 mg of MOTS-c?
At 10 mg/mL it is 50 units (0.5 mL). At 5 mg/mL it is 100 units (1 mL). Units depend on your exact concentration.
