Calculate exact reconstitution volumes for laboratory research peptides. Select a product preset or enter custom values. For research use only — this tool performs arithmetic only and does not provide medical or dosing advice.
Please select all options to see the calculation.
Exceeds syringe capacity!
Volume needed for a given number of IU after reconstitution (100 units = 1 mL on a U-100 scale). Values rounded to 2 decimal places (e.g. 0.125 mL is shown as 0.13); the calculator above shows 3 decimals.
| IU in vial (dry powder) | Bacteriostatic water added (mL) | Volume for 250 IU (mL) | Volume for 500 IU (mL) | Volume for 1,000 IU (mL) |
|---|---|---|---|---|
| 5,000 | 5 | 0.25 | 0.5 | 1 |
| 5,000 | 10 | 0.5 | 1 | 2 |
| 10,000 | 5 | 0.13 | 0.25 | 0.5 |
| 10,000 | 10 | 0.25 | 0.5 | 1 |
FOR RESEARCH PURPOSES ONLY. For in-vitro laboratory research use only. Not for human or veterinary use. This tool performs arithmetic only and does not provide medical, dosing or usage advice. Verify all calculations independently.
Concentration (mg/mL) = peptide mass in the vial ÷ bacteriostatic water added. Volume for a desired aliquot = target aliquot ÷ concentration. On a U-100 syringe, 100 units = 1 mL, so units = volume (mL) × 100.

It converts vial peptide mass and bacteriostatic water volume into concentration (mg/mL), then into the volume and U-100 syringe units for a desired laboratory aliquot. It is arithmetic only.
Choose a product preset or enter values manually: Target mass (desired aliquot), Total peptide in vial, and the bacteriostatic water you plan to add. The tool returns concentration, volume, and syringe units.
It is the amount of peptide you want in a single laboratory sample or working portion—not a medical dose. Use it only for research math and protocol planning.
On a U-100 syringe, 100 units = 1 mL. Units ≈ volume (mL) × 100. Always confirm markings on the syringe you are using in the lab.
Follow your lot’s certificate of analysis and your lab SOP. Many lyophilized research peptides are reconstituted with bacteriostatic water, but that is not a universal rule for every compound.
