Common Questions

Quick answers to the questions we hear most often.

What is bacteriostatic water?
Bacteriostatic water is sterile water containing 0.9% benzyl alcohol as a preservative. Unlike single-use sterile water, the preservative prevents bacterial growth and allows the vial to be accessed multiple times over a 28-day period.
How is your bacteriostatic water different from competitors?
Every batch of our bacteriostatic water is manufactured in the USA under cGMP standards and undergoes rigorous testing before release. We provide a Certificate of Analysis for every lot number, offer competitive pricing with bulk savings up to 22%, and ship same-day on all orders placed before 2:00 PM PT.
Do you offer free shipping on bacteriostatic water?
Yes — every order ships free with standard shipping within the United States. No minimum purchase required. Expedited shipping options are also available at checkout.
How quickly will my bacteriostatic water order ship?
Orders placed before 2:00 PM Pacific Time, Monday through Friday, ship the same business day. Orders placed after the cutoff or on weekends ship the next business day.
What is your return policy?
We offer a 30-day satisfaction guarantee on all unopened products. If your order arrives damaged, just send us a photo and we will replace it or issue a full refund. Opened vials cannot be returned as sterility cannot be verified.
Do you offer wholesale pricing on bacteriostatic water?
Yes. We offer custom pricing for orders of 200+ vials. Visit our Wholesale page to learn more and submit an inquiry.
