How much bacteriostatic water do you add to a 5 mg MOTS-c vial?

A common choice is 2 mL, giving a concentration of 2.5 mg/mL. The exact volume is up to you — more water makes a more dilute, easier-to-measure solution. Use the calculator above to match your target dose to a clean syringe mark.

How many units of MOTS-c do I draw for a 5 mg dose?

With a 5 mg vial in 2 mL of BAC water, a 5 mg dose is 200 units on a U-100 insulin syringe.

MOTS-c reconstitution calculator

Also known as Mitochondrial ORF of the 12S rRNA-c

Reconstitute MOTS-c by adding bacteriostatic water to the vial, then draw your dose on a U-100 insulin syringe. The calculator is pre-filled with commonly-referenced vial sizes (5, 10 mg) and water volumes (2, 3 mL) — every field is yours to override. Mitochondrial-derived peptide studied for metabolic effects.

New to this? How to use the calculator

1Enter what's on your vial. Type the peptide amount (mg) printed on the vial and the mL of bacteriostatic water you mixed in. Not sure how much water to add? Switch to the Solve: water tab and it tells you.
2Enter your dose — mind the unit. Type your target dose and pick mg or mcg with the toggle. This matters: 1 mg = 1000 mcg. GLP-1s (semaglutide, tirzepatide) are usually mg; most peptides (BPC-157, ipamorelin) are mcg.
3Read “Draw to … units”. The big number is how far to pull the plunger on a U-100 insulin syringe. Match it to the fill line on the syringe picture. The concentration and doses per vial are shown so a wrong answer looks wrong.

Three ways to use it

Solve: units — you know the dose; find how far to draw.
Solve: water — you want a round mark like 10 units; find how much water to add.
Solve: dose — you already drew some units; find the dose that was.

I have a vial, water and a dose — how many units do I draw?

Target dose

Check the unit: 1 mg = 1000 mcg.

Syringe size

U-100 insulin syringe — 1 mL holds 100 units.

Draw to

200 units

Concentration: 2.5 mg/mL
Volume per dose: 2 mL
Doses per vial: 1

This dose needs 200 units, but a 0.5 mL syringe only holds 50. Use less BAC water (a higher concentration), split the dose, or pick a larger syringe.
