Peptide Reconstitution Calculator
Enter your vial size, bacteriostatic water and target amount to see exactly how many units to draw on a U-100 insulin syringe.

Syringe size
All standard insulin syringes use the same U-100 scale (1 unit = 0.01 mL). A smaller barrel just makes small amounts easier to read.

How the math works
- Concentration (mg/mL) = vial mg ÷ water mL
- Units to draw = (amount mcg ÷ (vial mg × 1000)) × water mL × 100
- Doses per vial = (vial mg × 1000) ÷ amount mcg, rounded down
Example: a 5 mg vial with 2 mL of water is 2.5 mg/mL (25 mcg per unit). 250 mcg = 10 units = 0.10 mL.
