Bacteriostatic Water for Injection is a sterile, non-pyrogenic preparation containing 0.9% (9 mg/mL) benzyl alcohol as a preservative. The benzyl alcohol prevents bacterial growth in the vial, allowing peptides to be safely reconstituted and drawn from over multiple days.

BioInfinity bacteriostatic water is prepared and sealed under sterile conditions and is the standard diluent used to reconstitute research peptides such as BPC-157, TB-500, Ipamorelin, GHK-Cu, GLP-1 analogs, and virtually every lyophilized peptide sold on this site. For research use only. Not for human or veterinary consumption.

Researchers should refer to peer-reviewed publications for primary sources on this compound. Bacteriostatic Water is sold strictly for laboratory research use and is not intended for human or veterinary use.

Lyophilized Bacteriostatic Water stores at −20 °C protected from light; reconstituted solution refrigerates at 2–8 °C per laboratory SOP. Reference your lot's COA for compound-specific guidance and see our [Preparation Guide](/learn/preparation-guide) for laboratory handling instructions.

BioInfinity ships Bacteriostatic Water same-day from New York for all orders placed before 2 PM ET, Monday through Friday. We use insulated cold-shipping where indicated. International researchers should review our /shipping page for region-specific guidance.
