Quick math example
A 10 mg vial mixed with 2 mL gives 5 mg/mL. A 5 mg dose is 1.0 mL, which equals 100 units on a U-100 syringe.
How the MOTS-c calculation works
MOTS-c is typically labelled in milligrams per vial. The calculator first divides the vial mg amount by your BAC water volume to find concentration, then divides your target dose by that concentration.
Once concentration is known, every dose becomes target mg divided by mg per mL.
- 10 mg vial = 10,000 mcg total
- 10,000 mcg / 2 mL = 5,000 mcg per mL
- 5,000 mcg target = 1.0 mL draw
Re-check the math when anything changes
Recalculate whenever vial size, BAC water amount, target dose, or syringe type changes. Saving the setup in PepSync keeps the values tied to your protocol.
Frequently asked questions
Is MOTS-c approved as a medicine?+
Approval status varies by jurisdiction and use case. This page only explains calculator math and does not make treatment recommendations.
Why does my MOTS-c draw volume look large?+
MOTS-c doses are typically in the multi-milligram range, so draws can approach the full capacity of a 1 mL insulin syringe. You can lower draw volume by reducing BAC water or using a higher-strength vial.
Can PepSync save a MOTS-c protocol?+
Yes. The app saves vial size, water volume, dose, schedule, and reminders together so the calculator inputs do not need to be re-entered each cycle.
