Enter your vial size and bacteriostatic water, then convert any dose between mg, mcg, mL, and insulin-syringe units, both directions. The same math PepWise runs for every dose in your protocol.

PepWiseEnter a dose in mcg or mg to get the units to draw. Or switch the unit to units to work backward from the syringe to the dose. Changing the vial or water updates everything.
Concentration is the vial amount in milligrams divided by the water you add. Each syringe unit is a fixed slice of a milliliter (0.01 mL on a U-100), so the peptide it holds depends entirely on that concentration. Add more water and every unit holds less. For the full explanation with a worked example, see how many units is my dose.
Deciding how much water to add in the first place? Use the reconstitution calculator. Working backward from a target concentration? Try the reverse BAC calculator. Browse molecule guides in the peptide encyclopedia.
PepWise stores your vial size, water, and target dose per peptide and shows the exact units to draw every time, then logs each dose with its injection site and turns it into a provider PDF. Start free.
Concentration = vial mg ÷ water mL. On a U-100 syringe, amount per unit (mcg) = concentration × 10. Units = dose (mcg) ÷ amount per unit.
Depends on concentration. A 5 mg vial in 2 mL is 25 mcg per unit, so 250 mcg is 10 units on a U-100 syringe.
