What is Bacteriostatic Water?
Bacteriostatic Water is sterile, non-pyrogenic water for injection
that contains 0.9% benzyl alcohol as a preservative.
It is not a peptide, but rather a solvent commonly used to reconstitute lyophilized (freeze-dried) peptides,
hormones, and other compounds for research purposes.
The bacteriostatic agent (benzyl alcohol) inhibits bacterial growth,
allowing multiple withdrawals from the same vial under sterile conditions.
Bacteriostatic Water Composition

| pH | ~5.7 (range 4.5–7.0) |
Bacteriostatic Water Research Uses
1. Reconstitution of Lyophilized Compounds
Primarily used for dissolving freeze-dried peptides and hormones into solution
for laboratory and research applications.
2. Multi-Dose Applications
The addition of benzyl alcohol allows for repeated withdrawals from the same vial,
making it more practical for research protocols requiring multiple uses.
3. Laboratory Testing
Used in controlled laboratory conditions as a sterile diluent for injectable compounds under research settings.
Storage & Stability
Bacteriostatic Water should be stored at controlled room temperature (20–25°C / 68–77°F).
Once opened, vials can typically be used for up to 28 days if stored under sterile conditions.
After this period, contamination risk increases and the solution should be discarded.
