Laboratory Reconstitution Calculator
Three calculators for research peptide preparation. Enter your vial and water details to calculate concentration per mL, the quantity contained in a drawn volume, or the exact volume to draw for a target quantity. For laboratory reference only — not a dosing guide.
Concentration Calculator
Enter vial quantity and bacteriostatic water volume to calculate the resulting concentration per mL. This is the starting point for all subsequent calculations.
Output = concentration per mL (mcg/mL and mg/mL). For laboratory reference only — not a dosing guide.
Volume Analysis Calculator
Given your vial details and the volume drawn into a syringe, calculate the exact quantity (mcg and mg) contained in that drawn volume.
Volume Planning Calculator
Enter your target research quantity in either mcg or mg — the other field auto-fills. Then add your vial details to calculate the exact volume to draw.
Output = volume to draw in mL and equivalent units on a U-100 insulin syringe. For laboratory reference only.
Common Concentration Reference
Standard reconstitution concentrations for common vial sizes. For laboratory planning reference only.
| Vial Size | BW Added | mcg/mL | mg/mL |
|---|---|---|---|
| 2 mg | 1 mL | 2,000 mcg/mL | 2 mg/mL |
| 2 mg | 2 mL | 1,000 mcg/mL | 1 mg/mL |
| 5 mg | 1 mL | 5,000 mcg/mL | 5 mg/mL |
| 5 mg | 2 mL | 2,500 mcg/mL | 2.5 mg/mL |
| 10 mg | 1 mL | 10,000 mcg/mL | 10 mg/mL |
| 10 mg | 2 mL | 5,000 mcg/mL | 5 mg/mL |
| 10 mg | 5 mL | 2,000 mcg/mL | 2 mg/mL |
| 50 mg | 5 mL | 10,000 mcg/mL | 10 mg/mL |
| 50 mg | 10 mL | 5,000 mcg/mL | 5 mg/mL |
