How the math works

Concentration = vial mg ÷ water mL. One mL is 100 insulin units, so each unit holds concentration ÷ 100 mg. Units to draw = dose ÷ (mg per unit). Example: a 10 mg vial with 3 mL of water is 3.33 mg/mL, or 33.3 mcg per unit, so a 200 mcg dose is 6 units. Full walkthrough: how to reconstitute peptides.

Frequently asked

How does a peptide reconstitution calculator work?

It divides the vial amount by the water volume to get the concentration, converts that to micrograms per insulin unit (mg/mL × 10), then divides your dose by that figure to give the units to draw.

How many units is 100 mcg?

At 3.33 mg/mL (33.3 mcg per unit) it is 3 units; at 5 mg/mL it is 2 units; at 10 mg/mL it is 1 unit. Concentration decides it, so enter your own vial and water above.

What is 1 unit on an insulin syringe in mL?

0.01 mL. 100 units = 1 mL, 50 units = 0.5 mL.

Does the calculator work for IU peptides like HCG?

Yes. Use the per-compound calculators for IU-dosed compounds; they keep the vial and dose in IU and still give the syringe units.

Dosify Me does this math for you. Pick the compound, your vial size and dose, and the app draws the exact syringe reading, keeps your schedule and reminders, and logs every dose — privately, on your phone.
