MOTS-c calculator
Enter your MOTS-c vial size, the water you added, and a dose. PepExact returns the exact units on a U-100 insulin syringe — and shows the arithmetic behind it.
The fields below are generic example numbers, filled in so you can see the calculator work — they are not a recommended MOTS-c dose. Clear them and enter your own vial size, water, and dose.

Show the math
- 1. Concentration: 5 mg ÷ 2 mL = 2.5 mg/mL (2,500 mcg/mL)
- 2. Volume for one dose: 250 mcg ÷ 2,500 mcg/mL = 0.1 mL
- 3. Syringe units (U-100): 0.1 mL × 100 units/mL = 10 units
- 4. Doses in the vial: 5,000 mcg ÷ 250 mcg = 20 full doses

About this calculator
MOTS-c is a mitochondrial-derived peptide — a short peptide linked to mitochondrial DNA — that has been examined in laboratory research.
MOTS-c vials are commonly labelled in milligrams. Enter whatever your vial actually says, along with your water and dose, and the calculator does the rest.
Whatever the compound, this page only does arithmetic. It turns a vial size in milligrams, the water you add in millilitres, and a dose into the number of units on a U-100 insulin syringe — and shows every step. It does not know, store, or suggest what any dose should be.
The most common measurement slip is milligrams versus micrograms: 1 mg is 1,000 mcg. Keep the unit switch on the dose field set to whatever your number is actually written in, and the arithmetic stays honest.

Common questions
How do I calculate MOTS-c syringe units?
Concentration is vial milligrams ÷ water millilitres; volume is your dose ÷ that concentration; units are volume in mL × 100 on a U-100 insulin syringe. PepExact runs all three steps and shows the working.
How much water should I use to reconstitute MOTS-c?
The water volume is your choice and changes only the concentration, not how much peptide is in the vial. More water makes each draw larger and easier to read; less water makes it smaller. The reconstitution calculator solves for the water volume that lands a dose on a round number of units.
Does PepExact recommend a MOTS-c dose?
No. It is a measurement calculator only. It converts a vial, a water volume, and a dose you already have into syringe units, and never suggests a dose.
