Bac Water – Technical Brief (Research-Use-Only)
1. Identity
Bacteriostatic Water is a sterile, non-pyrogenic solution containing 0.9% benzyl alcohol, which acts as a preservative to inhibit bacterial growth. It is commonly used for diluting medications and peptides before injection.
2. Mechanism of Action
Bacteriostatic Water works by:
- Preventing bacterial contamination: The benzyl alcohol inhibits microbial growth.
- Extending usability: Unlike sterile water, it can be used multiple times within 28 days.
- Providing a safe diluent: Used for reconstituting peptides, hormones, and injectable medications.
3. Uses
Bacteriostatic Water is primarily used for:
- Reconstituting peptides: Ensures sterility when mixing lyophilized powders.
- Diluting injectable medications: Used in hormone therapy, vitamin injections, and research
4. applications.
- Multi-dose vials: Allows repeated withdrawals without contamination.
5. Dosage
- Standard concentration: 0.9% benzyl alcohol in sterile water.
- Usage: Typically 1–3ml per vial for peptide reconstitution.
- Administration: Used subcutaneously or intramuscularly, depending on the medication.
6. Safety Profile
- Common side effects: Mild irritation at the injection site.
- Precautions: Not suitable for intravenous injection without additives.
- Long-term effects: Generally well-tolerated when used correctly.

- Shelf life: Remains sterile for up to 28 days after opening.
- Do not freeze: Freezing can degrade the preservative.
8. Legality in the UK
Bacteriostatic Water is legal and widely available in the UK for research and medical use. It can be purchased from pharmacies and online suppliers, but regulations may vary depending on its intended application.
