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.

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 have a dose, find the draw), Solve: water (you want a clean mark like 10 units, find the water), and Solve: dose (you drew some units, find the dose).

Doses / vial

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.

Track this protocol

This tool computes volumes only — it does not recommend doses. Any pre-filled values are commonly-referenced examples to confirm with your provider. Always verify the concentration and draw against your own vial and syringe.

MOTS-c concentration quick-reference

Vial	BAC water	Concentration	Units for 5 mg
5 mg	2 mL	2.5 mg/mL	200 u
5 mg	3 mL	1.67 mg/mL	300 u
10 mg	2 mL	5 mg/mL	100 u
10 mg	3 mL	3.33 mg/mL	150 u
