Bacteriostatic Water 3ml / 10ml

Bac water is the everyday shorthand for bacteriostatic water — sterile water containing 0.9% benzyl alcohol as a preservative, used to reconstitute lyophilised research peptides. The benzyl alcohol is what allows a vial to be entered multiple times without the contents spoiling.

Bacteriostatic water is used to reconstitute lyophilised peptides into a liquid solution suitable for laboratory research, while the benzyl alcohol content inhibits bacterial growth between uses - a step common to almost every research peptide protocol used by Australian researchers.

Yes. Bac water is simply the abbreviated name, and some people write it bacto water. All refer to bacteriostatic water for injection — a preserved sterile diluent used for peptide reconstitution.

Yes — PhaseOne has bac water for sale online in 3ml and 10ml sealed vials, shipped Australia-wide. Because chemists do not stock it for retail sale, ordering online from a research supplier is the usual route. The things to check on any listing are that vials arrive sealed and that the benzyl alcohol concentration is stated, since that is what makes a vial multi-use rather than single-use.

Chemist Warehouse and other Australian chemists do not generally stock bacteriostatic water for retail sale — it is a preserved laboratory diluent rather than a consumer product, and is usually supplied through research suppliers instead. PhaseOne ships bac water Australia-wide in sealed 3ml and 10ml vials.

PhaseOne supplies bac water Australia-wide in 3ml and 10ml sealed vials, dispatched locally with tracking, and it is commonly ordered alongside research peptides for reconstitution.

PhaseOne prices bac water at A$7.49 for a 3ml vial and A$14.99 for a 10ml vial. Current pricing for both sizes is shown on this page.

Plain sterile water contains no preservative and is intended for single use — once entered it should be discarded. Bacteriostatic water's 0.9% benzyl alcohol content inhibits bacterial growth and allows safe use across multiple reconstitution draws from one vial.

Bacteriostatic sodium chloride is preserved 0.9% saline, while bacteriostatic water is preserved water with no salt content. Plain normal saline contains no preservative and is single-use. For peptide reconstitution, bac water is the more common choice because it introduces no additional solutes.

Acetic acid is used as a diluent for peptides with poor solubility in neutral water. Bacteriostatic water suits most research peptides, while dilute acetic acid is reserved for compounds that will not readily dissolve. (!) Read our full bac water vs acetic acid comparison.

The volume of bac water used depends on the peptide and the concentration required for research purposes. Our reconstitution guide outlines general ratios across common research peptides, and our (!) peptide dosage calculator works out draw volumes for you.

Once opened, bacteriostatic water should be refrigerated and used within the timeframe recommended on the vial label to maintain sterility for ongoing research use. (!) Read our full peptide reconstitution guide.

Yes - every batch is sealed and quality-checked prior to dispatch, with stock shipped Australia-wide alongside our full peptide research range.

Bac water is the standard diluent supplied to Australian researchers across our full research peptide range. (!) See our BPC-157, Retatrutide, CJC-1295 No DAC, and Ipamorelin.
