Bacteriostatic water is sterile water containing 0.9% benzyl alcohol — a preservative that inhibits bacterial growth, which is why it is the standard diluent for reconstituting research peptides.

Why benzyl alcohol matters

It lets a reconstituted vial be sampled over multiple weeks without the solution spoiling, unlike plain sterile water.

Storage

Keep sealed at room temperature away from light; refrigerate after first use and observe the beyond-use date on the vial.

Handling

Swab the stopper before each draw and use a sterile syringe. Browse bacteriostatic water.
