Peptide Reconstitution Calculator
Turn any peptide vial into an exact insulin-syringe draw. Enter the vial size, how much bacteriostatic water you're adding, and your target dose. We'll show mg/mL, the units to draw on a U-100 or U-40 syringe, and total doses per vial.
Common presets
Total peptide in the vial.
Volume of bacteriostatic water you reconstitute with.
Per-injection dose you want to draw.
U-100 = 100 units per mL (standard). U-40 = 40 units per mL.
Draw
10.0 units
on a U-100 insulin syringe (0.100 mL)
Concentration
2.50 mg/mL
Per dose
250 mcg
Doses / vial
~20
How it works
- Concentration (mg/mL) = vial mg ÷ BAC water mL.
- Volume per dose (mL) = dose mg ÷ concentration.
- Syringe units = volume × 100 (U-100) or × 40 (U-40).
