Product Information

The Essential Foundation of Every Peptide Protocol

BAC Water (3mL) is available in Australia through Aus Peptide Supply with fast domestic shipping to all states and territories.

A sterile, pharmaceutical-grade solution containing 0.9% benzyl alcohol, BAC Water is the industry-standard reconstitution agent used by researchers working with lyophilised peptides. No serious peptide research protocol begins without it.

How It Works

The 0.9% benzyl alcohol concentration in Bacteriostatic Water serves as a preservative, inhibiting the growth of bacteria and other microorganisms upon entry into the vial. This allows researchers to reconstitute peptide compounds and draw multiple doses from a single vial over an extended period without compromising sterility or compound integrity — a critical advantage over standard sterile water, which is limited to single-use applications.

Frequently Asked Questions

What is bacteriostatic water?
Bacteriostatic water (BAC water) is sterile water containing 0.9% benzyl alcohol, which inhibits bacterial growth. This allows the vial to be used for multiple draws over time without contamination — making it the standard diluent for reconstituting lyophilized research peptides.
What is BAC water used for?
BAC water is used to reconstitute lyophilized (freeze-dried) peptide powders before use in research protocols. Adding BAC water to a lyophilized peptide vial dissolves the powder into a stable solution. The bacteriostatic agent preserves the solution between uses when stored correctly at 2–8°C.
What is 'backwater' or 'peptide water'?
Both are common search terms for the same product. 'Backwater for peptides' and 'bacwater' are frequent misspellings of BAC water — and if you have been searching for 'backwater peptides' or 'peptide water Australia', you are looking for Bacteriostatic Water. The correct term is Bacteriostatic Water (BAC water), which contains 0.9% benzyl alcohol in sterile water for injection. It is the industry-standard diluent used to reconstitute lyophilised peptide powders for research use.
How much BAC water do you add to a peptide vial?
The volume of BAC water added depends on the desired concentration. A common approach for a 10mg peptide vial is to add 1–2mL of BAC water, which gives a concentration of 10mg/mL or 5mg/mL respectively. Use a sterile insulin syringe to inject the water slowly down the inside wall of the vial, then gently swirl to dissolve.
Is BAC water available in Australia?
Yes. BAC Water (3mL sterile vials) is available in Australia through Aus Peptide Supply with fast domestic shipping to all states and territories.
What size are your bacteriostatic water vials?
Our bacteriostatic water comes in 3mL sterile vials — the standard research size used for reconstituting peptide compounds. Researchers searching for 'bacteriostatic water 3ml vials' will find our product is exactly that format. Each vial contains 0.9% benzyl alcohol in sterile water for injection, individually sealed under sterile conditions, and is suitable for multi-dose use across a full peptide research protocol.
