Prostamax reconstitution chart — bacteriostatic water to concentration
Resulting concentration (mg/mL) when a lyophilized Prostamax vial is reconstituted with common bacteriostatic-water volumes, for research preparations. Add the diluent volume that reaches the mg/mL a research protocol specifies.
| Vial amount | +1 mL BAC water | +2 mL BAC water | +3 mL BAC water | +5 mL BAC water |
|---|---|---|---|---|
| 10 mg | 10 mg/mL | 5 mg/mL | 3.33 mg/mL | 2 mg/mL |
| 20 mg | 20 mg/mL | 10 mg/mL | 6.67 mg/mL | 4 mg/mL |
Frequently asked questions
How much reconstitution solution for 10 mg Prostamax?
For a 10 mg vial of Prostamax, the volume of bacteriostatic water added is what sets the concentration of the research preparation — the peptide mass itself does not change. Adding 1 mL of bacteriostatic water yields 10 mg/mL, 2 mL yields 5 mg/mL, and 3 mL yields 3.33 mg/mL. Choose the diluent volume that reaches the mg/mL a research protocol specifies, or enter any amount in the calculator above. Supplied for laboratory research use only.
How much bacteriostatic water do I add to 10 mg of Prostamax?
The amount of bacteriostatic water added to a 10 mg Prostamax vial is selected to reach a target concentration for a research preparation. To yield 5 mg/mL, add 2 mL; to yield 10 mg/mL, add 1 mL. This calculator performs the concentration and volume arithmetic (mass ÷ diluent volume). It is a lab-math utility for research use only, not medical or dosing guidance.
What concentration does Prostamax reach after reconstitution?
Concentration (mg/mL) equals the peptide mass in the vial divided by the volume of bacteriostatic water added. A 10 mg vial reconstituted with 2 mL of bacteriostatic water yields 5 mg/mL; with 1 mL it yields 10 mg/mL. The chart on this page lists common Prostamax vial amounts against several bacteriostatic-water volumes so the resulting concentration can be read directly. For research use only.
Does adding more bacteriostatic water change how much Prostamax is in the vial?
No. Adding bacteriostatic water changes the concentration (mg per mL), not the total mass of Prostamax in the vial. More diluent produces a more dilute research solution that requires a larger measured volume for the same amount; less diluent produces a more concentrated solution requiring a smaller measured volume. This tool computes those figures for reconstituted research solutions only.
