Sterile water with 0.9% benzyl alcohol added as a preservative. The benzyl alcohol stops bacteria from growing, so one vial can be drawn from more than once. It is the standard diluent for reconstituting powdered vials.

Up to 28 days after the first puncture when stored as directed. Write the date you first used it on the label and discard it after 28 days. Unopened vials are good until the expiry date printed on the label.

Yes, on every order with no minimum. Orders over $200 are upgraded to free UPS 2nd Day Air and orders over $400 to free UPS Next Day Air.

It depends on the vial size and the dose you want. Use the reconstitution calculator: enter the milligrams in the vial, the mL of water you add, and your dose, and it shows exactly how many syringe units to draw.

Sterile water has no preservative and is meant for single use. Bacteriostatic water contains 0.9% benzyl alcohol so it can be used for multiple draws over 28 days.

At room temperature, away from direct sunlight, with the cap on. Do not freeze it. Once opened, keep it upright and clean the stopper with an alcohol pad before each draw.
