Overview
Bacteriostatic water is sterile water containing 0.9% benzyl alcohol as a preservative. It is the standard solvent used to reconstitute lyophilized (freeze-dried) peptides for subcutaneous injection. The benzyl alcohol prevents bacterial growth, allowing a reconstituted vial to remain stable in the refrigerator for up to 28 days.
Mechanism of action
Not a peptide — a reconstitution accessory. The benzyl alcohol acts as a bacteriostatic preservative, keeping the solution sterile across the typical 4-week use window of a reconstituted vial.
Reported benefits
- Required for proper reconstitution of any lyophilized peptide
- 28-day stability window post-reconstitution
- Sterile and ready-to-use
- Compatible with virtually all research peptides
Research dosing
Reconstitution volume depends on the peptide and desired concentration. Our BAC water calculator handles the math automatically.
Considerations
Always pair every peptide order with sufficient BAC water. Store reconstituted vials refrigerated (2–8°C) and use within 28 days.
