This only labels your calculation with a peptide name, for your own reference. It does not fill in, choose, or suggest any values. Enter your syringe, vial strength, water, and dose yourself below, based on your own supplies.

1. Syringe size U-100 insulin syringe

Choose the barrel size printed on your syringe. It sets the unit scale (a U-100 syringe always reads 100 units per full mL, whatever its size).

2. Vial strength milligrams (mg)

This is the total amount of peptide (in mg) freeze-dried inside the vial, printed on the label or certificate of analysis.

mg
3. Bacteriostatic water millilitres (mL)

The volume of solvent you mix into the vial. More water means a more dilute solution; less water means a more concentrated one.

mL
4. Target dose micrograms (mcg)

The amount (in mcg) you intend to draw per injection. The calculator instantly tells you where to stop pulling the plunger.
