What Is Bacteriostatic Water?
Bacteriostatic Water is sterile water containing 0.9% benzyl alcohol as a bacteriostatic preservative, used to reconstitute lyophilized research peptides. The preservative inhibits bacterial growth, allowing a reconstituted vial to be used across multiple research sessions rather than a single use.
Purity & Third-Party Testing
Every batch of Bacteriostatic Water from True Vision Peptides undergoes quality control testing and ships with a supporting Certificate of Analysis (COA), and you can request a reprint at any time.
How It’s Used
Bacteriostatic Water is drawn into a syringe and slowly injected along the vial wall of a lyophilized peptide to reconstitute it, avoiding direct force on the powder. For reconstitution ratio reference, see our dosage calculator and FAQ. Additional research ancillaries are available in our Ancillaries category.
Storage & Handling
Store Bacteriostatic Water refrigerated between 2°C and 8°C. Once opened, use within the timeframe indicated on your COA and handle using proper aseptic technique.
