Overview
Bacteriostatic water is USP-grade sterile water containing approximately 0.9% benzyl alcohol as a preservative, which inhibits bacterial growth across multiple uses from the same vial. It is not a research peptide itself, but the standard diluent used to reconstitute lyophilized (freeze-dried) peptides into a liquid form suitable for laboratory use.
Genesis Genetics supplies bacteriostatic water exclusively for laboratory and research applications, as a reconstitution aid for the peptides in our catalog.
Research Context
Because benzyl alcohol is the active preservative, bacteriostatic water is generally distinguished in research protocols from plain sterile water (which has no preservative and is intended for single-use reconstitution only). Most peptides in our catalog list bacteriostatic water as a curated companion product specifically for this reason.
Purity & Analytical Testing
Each lot is verified to USP-grade sterility and purity standards before release, documented on the included Certificate of Analysis.
For more on how this testing fits into our broader release process, see Quality Control. For what the Certificate of Analysis itself contains, see Certificate of Analysis.
Storage & Handling
Store at room temperature away from direct light. Once a vial is opened, most protocols call for use within roughly 28 days, after which the preservative's effectiveness can no longer be assured — discard and use a fresh vial after that window.
For a full walkthrough of reconstitution technique and stability windows, see our research article on Peptide Storage 101, and shipping/cold-chain handling for temperature sensitive orders is covered on our Shipping & Cold Chain page.

Frequently Asked Questions
What is bacteriostatic water used for?+
It is used to reconstitute lyophilized (freeze-dried) peptides into a liquid form, and its benzyl alcohol preservative allows a single vial to be used for multiple reconstitutions without re-sterilizing.
How is it different from plain sterile water?+
Plain sterile water has no antimicrobial preservative and is intended for a single use; bacteriostatic water's benzyl alcohol content inhibits bacterial growth across repeated draws from the same vial.
How long does an opened vial last?+
Most laboratory protocols treat an opened vial as usable for about 28 days before the preservative's effectiveness can no longer be assured. Follow your own protocol's guidance.
Is bacteriostatic water approved for human injection?+
No. As sold by Genesis Genetics, bacteriostatic water is supplied strictly for laboratory and research use, not for human or veterinary administration.
