Reconstitution & Dosing Calculator
Compute concentration, volume per dose, and the exact units to draw on a U-100 insulin syringe — for lyophilised research-grade peptide compounds.
Draw to

units on a U-100 insulin syringe
- Vial concentration
- 2.50 mg/mL
- Volume per dose
- 0.100 mL
- Doses per vial
- 20.0
Formula: vol = dose_mg / (peptide_mg / bac_mL); units = vol × 100.
How to use this calculator
- Enter the peptide amount per vial (typically 5 mg or 10 mg).
- Enter the bacteriostatic water you reconstituted the vial with (1–5 mL is typical).
- Enter the dose per administration in micrograms (mcg).
- The calculator outputs the volume to draw (mL) and the corresponding units on a U-100 insulin syringe.
- Select your syringe size to confirm the calculated dose fits in a single draw.
The math, briefly
- Concentration: peptide_mg / bac_water_mL = mg/mL
- Volume per dose: dose_mg / concentration = mL
- Syringe units (U-100): volume_mL × 100
- Doses per vial: peptide_mg / dose_mg
Reconstitution supplies
Standard reconstitution diluents for research-grade lyophilised peptide compounds:
- Bacteriostatic Water (3 mL / 10 mL) — USP-grade 0.9% benzyl-alcohol solution, the standard reconstitution diluent.
- Acetic Acid Water (10 mL) — 0.6% acetic acid solution for compounds requiring acidic buffer.
