Bacteriostatic Water

Overview

What is Bacteriostatic Water?

Bacteriostatic water is sterile water containing 0.9 percent benzyl alcohol as a preservative, used to reconstitute lyophilised peptides. The preservative inhibits bacterial growth, allowing a vial to be entered more than once across a storage period.

What the research reports

Benefits of Bacteriostatic Water

Outcomes described across the published Bacteriostatic Water literature and ongoing study. Read each as research context, not a promised result.

1. 01

   Multiple vial entry support

   The benzyl alcohol preservative inhibits bacterial growth, which is what allows a reconstituted vial to be entered more than once. Reported in research settings.

2. 02

   Extended storage window use

   Preserved diluent supports storage across days or weeks refrigerated, where plain sterile water would allow contamination. Reported in research settings.

3. 03

   Standard reconstitution fluid

   The default diluent named in most peptide reconstitution protocols, which makes volume calculations directly comparable. Reported in research settings.

4. 04

   Widely available lab supply

   Sold as a standard laboratory and pharmacy item, so sourcing does not carry the purity uncertainty peptides themselves do. Reported in research settings.

5. 05

   Predictable volume handling

   Supplied in fixed volume vials, so dilution maths and concentration per unit can be calculated reliably in advance. Noted across the published research record.

Dosage and protocol

Dosage and protocol reference

Volume is chosen to give a workable concentration, commonly 1 to 3 mL per vial. Store the reconstituted product refrigerated. Figures describe study protocols, not a personal regimen.

Route

Diluent for injection

Example range

1-3 mL per vial

Frequency

As required

Timing

Add slowly down the vial wall. Swirl gently, never shake the vial.

Interactions

How it pairs with other peptides

Sterile water

Unpreserved sterile water suits single use only, since it does not inhibit bacterial growth after entry.

Neonatal use

Benzyl alcohol is contraindicated in newborns, so preserved diluents must not be used in that setting.

Sodium chloride

Bacteriostatic saline is an alternative preserved diluent, though some peptides are less stable in it.

Acetic acid

Used for peptides that will not dissolve in water, after which a preserved diluent completes the volume.
