Common questions
How many units is 0.5mg of MOTS-C?
With a 10mg vial mixed in 2ml, 0.5mg is 10 units on a U-100 insulin syringe. With 3ml of water it would be 15 units: more water means more units for the same dose, which is easier to measure for small doses.
How much bacteriostatic water do I add to a 10mg vial of MOTS-C?
2ml is the common default; anywhere from 2ml to 3ml is fine. More water doesn’t change the dose, only how many units it takes to draw it. See mixing a vial.
What if I miss a MOTS-C dose?
Never double up. Skip it and take the next one at your usual time. The missed doses guide has the rule for each peptide. Dose-day emails above come with an “I took it” button so you never have to wonder.
