MOTS-c 10 mg reconstitution calculator
How much bac water for MOTS-c 10 mg?
There’s no single right amount: the water sets the strength, not how much MOTS-c is in the vial, so use the volume on your pharmacy’s instructions. For example, 1 mL makes 10 mg/mL and 2 mL makes 5 mg/mL; the table below shows what each volume means on a U-100 syringe.

What each volume makes
| Water | Strength | Each unit | 1 mg is |
|---|---|---|---|
| 1 mL | 10 mg/mL | 100 mcg | 10 units |
| 2 mL | 5 mg/mL | 50 mcg | 20 units |
| 2.5 mL | 4 mg/mL | 40 mcg | 25 units |
Examples; use the volume on your pharmacy’s instructions. Units are on a U-100 syringe: 100 units = 1 mL.
About the 10 mg vial
Nothing official stands behind the 10 mg
MOTS-c has no FDA-approved label, so no regulator has set a water volume or checked that the vial holds 10 mg. The FDA calls MOTS-c free base “not well-characterized”, notes it has no USP or NF monograph and isn’t a component of any FDA-approved drug, and says it “has not identified any human exposure data on drug products containing MOTs-C administered via any route of administration” (FDA, FDA briefing). It also flags possible “peptide-related impurities”. The calculator can only work from the number printed on your label, so its figures are arithmetic on an amount nobody has verified. Ask a pharmacist before mixing.
Storage figures online aren't FDA advice
The storage numbers that circulate for MOTS-c come from published literature that the FDA quoted in its July 2026 briefing document: freeze-dried powder “is stable when stored at -20°C desiccated and protected from light”, and once mixed, kept at +4°C “between 2-7 days” (FDA briefing). They are literature figures, not an FDA recommendation. The same document warns that peptides “can be extremely sensitive” to conditions such as pH, heat, concentration and impurities, “which may lead to the aggregation and degradation of peptides”. The water you add sets the concentration the peptide sits in, so ask your pharmacist how long your mixed vial keeps and follow the label.
With 1 mL, every unit is 100 mcg
Each unit on a U-100 syringe is 0.01 mL, so what a unit holds depends on the water. With 1 mL the vial is 10 mg/mL and each unit holds 100 mcg; with 2 mL it’s 5 mg/mL (50 mcg per unit); with 2.5 mL it’s 4 mg/mL (40 mcg per unit). Less water means fewer units for the same amount, but each unit counts for more: misreading by one unit is 100 mcg at 1 mL and 40 mcg at 2.5 mL, two and a half times smaller. At 1 mL the whole 10 mg fits in one 100-unit syringe. If you use a different volume from one vial to the next, work your units out again from the amount your prescriber gave you.

About MOTS-c
US regulatory status
Not approved for human use in the US
MOTS-c is not approved by the FDA for any use. The FDA moved it off its Category 2 safety-risk list after the nomination was withdrawn, and it is not on any list that lets pharmacies compound it. In July 2026 an FDA advisory committee narrowly voted to recommend adding it to the 503A bulks list, against the FDA staff’s proposal; the vote is not binding, and as of October 16, 2026 the FDA had not published a proposed or final rule.

How this MOTS-c calculator works
This MOTS-c reconstitution calculator starts from the 10 mg in your vial. Add the water you mix it with and the dose your prescriber gave you; it divides the mg by the mL to get the strength, then turns your dose into mL and units on a 30, 50 or 100-unit syringe.
Peptinote never suggests a dose or a water volume. The example volumes are there to make the math easy to check, not as advice. For the full method, see the peptide calculator.
Questions people ask
How much bac water MOTS c 10mg?
There’s no single right amount: use the volume on your pharmacy’s instructions. The water only sets the strength; the vial still holds 10 mg however much you add. With 1 mL it’s 10 mg/mL (100 mcg per unit), with 2 mL 5 mg/mL (50 mcg per unit) and with 2.5 mL 4 mg/mL (40 mcg per unit). Enter your volume and prescribed dose above to get the units. This product isn’t FDA-approved, so no official label sets a water volume and its contents aren’t verified.
How much bac water with 10mg MOTS c?
Whatever volume you add, only the strength changes; the vial still holds 10 mg. More water spreads it out, so each unit holds less and the same dose takes more units: easier to measure, but more liquid to inject. Going from 1 mL to 2.5 mL takes each unit from 100 mcg to 40 mcg. Check the volume on your pharmacy’s instructions first. This product isn’t FDA-approved, so no official label sets a water volume and its contents aren’t verified.
How much bac water for MOTS-c?
Use the volume your pharmacy specifies, and never more than the vial itself can hold (its size in mL, not the 10 mg on the label). If you weren’t given a volume, ask a pharmacist before mixing. For reference, the bac water calculator shows the arithmetic: water (mL) = vial mg × units ÷ (dose mg × 100). This product isn’t FDA-approved, so no official label sets a water volume and its contents aren’t verified.
How do I reconstitute MOTS-c 10 mg?
Wipe both stoppers with alcohol and let them dry. Draw the volume of bacteriostatic water your pharmacy specifies into a new syringe, add it slowly down the inside of the vial, then swirl gently until clear; don’t shake. Label it with the strength: 10 mg in 1 mL is 10 mg/mL. Full steps: how to reconstitute peptides.
How do I reconstitute MOTS-c?
Mixing your MOTS-c 10 mg vial takes the bacteriostatic water your pharmacy specifies and a new sterile syringe. Add the water slowly against the glass and swirl, never shake, until the liquid is clear. If it stays cloudy or has particles, don’t use it; call your pharmacy. Then write the strength and date on the vial and store it as the label says (how to store peptides).
Is there a peptide calculator for MOTS-c?
This page is the MOTS-c 10 mg reconstitution calculator. Enter the water you add (or tap an example volume) and your prescribed dose, and it shows the units to draw on a 30, 50 or 100-unit syringe, the strength, and the doses in the vial, with every step of the math. It never suggests a dose.
How do MOTS-c units convert to mg?
Units measure volume (1 unit = 0.01 mL), so converting them to mg needs the strength: mg = units ÷ 100 × mg/mL. In a 10 mg vial, with 1 mL each unit holds 100 mcg, with 2 mL each unit holds 50 mcg and with 2.5 mL each unit holds 40 mcg. Multiply by the units you draw, or let the calculator above do it, with every step shown.
Can Peptinote tell me how many units to take?
No. Peptinote never suggests a dose. Enter the dose your prescriber gave you, and the calculator shows how to measure it: the units, the mL and where the line sits on your syringe, with every step of the math. If you aren’t sure what your dose is, ask your prescriber or pharmacist before drawing anything. How our calculator works.
