How much water do I add to a 10 mg MOTS-c vial?

The water amount is your choice, it only changes how strong each mL is. With 2 mL you get 5 mg per mL; with more water each unit holds less, which makes small doses easier to measure.

How many units is 1 mg of MOTS-c?

It depends on the strength of your mix. At 5 mg/mL, 1 mg is 20 units. Enter your own vial and water in the calculator to get your number.

How long does mixed MOTS-c keep?

Follow the storage line on your product or prescription. Bacteriostatic water itself should be used within 28 days of the first needle, per CDC guidance.

MOTS-c dosage calculator

Enter your MOTS-c vial size, the amount of water you added and your dose; this shows the units to draw with a U-100 insulin syringe.

This is for reference only. Your dose is set by your prescriber or the product label; here we only convert it into units.

sizes of vials sold: 10, 40, 50 mg
status of approval: FDA-approved: No
Example mixture: 10 mg with 2 mL: Strength: 5 mg/mL

Working out the MOTS-c math

You get the strength by dividing the amount in the vial by the water. When 10 mg is mixed with 2 mL of water, each mL contains 5 mg. Divide your dose by that strength for mL, then multiply by 100 to get units on a U-100 syringe.

From that vial, 100 mcg equals 0.02 mL, or 2 units.

A quick look at MOTS-c units

Your dose	10 mg vial + 2 mL	40 mg vial + 2 mL	50 mg vial + 5 mL
400 mcg	8 units	2 units	4 units
500 mcg	10 units	2.5 units	5 units
750 mcg	15 units	3.8 units	7.5 units
1 mg	20 units	5 units	10 units
1.5 mg	30 units	7.5 units	15 units
2 mg	40 units	10 units	20 units
2.5 mg	50 units	12.5 units	25 units
3 mg	60 units	15 units	30 units
4 mg	80 units	20 units	40 units

Each cell shows the line you should draw to on a U-100 syringe when using that vial and water.

So is MOTS-c FDA-approved?

No FDA-approved status exists for any use in people; it is sold as a research chemical. Since no FDA label exists, there is no official dose. We just convert the dose you already have.

Follow the storage guidance shown on your product or prescription. Per CDC guidance, use bacteriostatic water itself within 28 days after the first needle.
