got questions?
What is Bacteriostatic water? (Bac Water)
Bacteriostatic water is sterile water containing 0.9% benzyl alcohol. The benzyl alcohol acts as a preservative that inhibits bacterial growth, so a single vial can be accessed for multiple withdrawals across a 28-day period rather than being discarded after one use. That repeat-access property is what separates it from plain sterile water and makes it the standard diluent for reconstitution. Bacteriostatic Water Store supplies genuine Hospira USP-grade bacteriostatic water in 30ml vials, alongside generic vials in 3ml and 10ml, all shipped manufacturer-sealed from a U.S. warehouse.
Can I use Bac Water for peptide reconstitution?
Yes. Bacteriostatic water is the standard diluent for reconstituting lyophilised peptides in a laboratory setting. Because the 0.9% benzyl alcohol keeps the solution sterile through repeated withdrawals, bac water for peptides is preferred over plain sterile water whenever a vial will be accessed more than once over its shelf life. Bacteriostatic Water Store stocks genuine Hospira USP-grade 30ml vials plus USP-grade generic 3ml and 10ml, with same-day U.S. shipping on orders placed before 2pm EST.
Do I need a prescription to buy bacteriostatic water?
Pharmacies like CVS and Walgreens typically keep bacteriostatic water behind the counter and ask for a prescription before dispensing it, which is why it is hard to pick up locally. Buying online from a dedicated supplier is the more direct route. Bacteriostatic Water Store ships genuine Hospira USP-grade 30ml and generic 3ml and 10ml vials manufacturer-sealed, direct to you.
What is the difference between bacteriostatic water and sterile water?
Sterile water contains no preservative, so once you draw from the vial it is single-use and any leftover has to be discarded. Bacteriostatic water’s 0.9% benzyl alcohol lets the same vial be accessed repeatedly across 28 days without the solution losing sterility. For multi-withdrawal reconstitution work, that is why bacteriostatic is the default choice over plain sterile water.
Can I buy Bac Water near me, or at CVS or Walgreens?
Usually not over the counter. CVS, Walgreens and most local pharmacies do not stock 30ml multi-dose bacteriostatic vials for general sale without a clinical prescription, which is why “bac water near me” so often comes up empty. Ordering online from a U.S. supplier is the reliable route. Bacteriostatic Water Store ships genuine Hospira and generic vials same day on orders placed before 2pm EST, so you are not dependent on local pharmacy stock.
Is "Reconstitution Solution" sold online the same as Bac Water?
Not always. Because bacteriostatic water is a regulated medical supply, some marketplace sellers relabel products as “reconstitution solution” to stay listed, and those often lack the 0.9% benzyl alcohol that makes the water bacteriostatic in the first place. Without the preservative you lose the multi-withdrawal sterility that reconstitution work depends on.
