What is bacteriostatic water?
Bacteriostatic water (bac water) is sterile water with 0.9% benzyl alcohol. The benzyl alcohol is a preservative that inhibits bacterial growth, so a vial can be accessed more than once, unlike plain sterile water.

You can buy bacteriostatic water directly from Simple Peptide on this page: our 10 mL ($8) or 30 mL ($18) multi-use vials, or the 30 mL Hospira brand ($30), in 1, 3 or 5 packs.
