Peptide Calculators
Reconstitution and dosing arithmetic, with every formula written out in full. Each calculator shows the working, a table of worked examples, and answers to the questions people ask most.
Peptide Reconstitution Calculator
Work out the concentration and syringe units after reconstituting a peptide vial. Enter vial strength, bacteriostatic water and dose to get the units to draw.
units = (dose mg ÷ (vial mg ÷ BAC water mL)) × 100
Peptide Dosage Calculator
Convert a peptide dose in milligrams to syringe units at any concentration. Supports U-100, U-50 and U-40 insulin syringes.
units = (dose mg ÷ concentration mg/mL) × syringe scale
BAC Water Calculator
See how the amount of bacteriostatic water changes your peptide concentration and the units you draw. Compare 1 mL, 2 mL, 3 mL and 5 mL side by side.
concentration mg/mL = vial mg ÷ BAC water mL
mg to Units Calculator
Convert milligrams to insulin syringe units at any concentration. A U-100 syringe holds 100 units per mL, so units depend on your mg/mL.
units = (mg ÷ mg per mL) × 100
