Bacteriostatic water is sterile water that contains a small amount of a preservative (usually 0.9% benzyl alcohol) to inhibit bacterial growth. It’s commonly used to dilute or dissolve peptides intended for injection.

Key points:

• Can be used for multiple doses from the same vial because the preservative helps prevent bacterial contamination.
• Not the same as sterile water for injection, which contains no preservative and is generally intended for single use.

Research use only. Not for human or veterinary use.
