Why source it here: the compounds come with real COAs
Bacteriostatic water is the diluent — the compounds you reconstitute with it are what matter. Every research compound in the catalog ships with a genuine, independent third-party certificate of analysis (Freedom Diagnostics HPLC + public Janoshik links) you can open and verify yourself. Buy your BAC water where the peptides are actually tested.

Bacteriostatic water dissolves the lyophilized powder; the research compound is the actual subject of study. These are among the most-referenced compounds researchers pair it with:
BPC-157
TB-500
Ipamorelin
GHK-CuReconstitution concentration calculator
Work out the concentration before you open anything: enter the compound mass in the vial and the volume of bacteriostatic water you plan to add, and this returns the resulting concentration in mg/mL and mcg per 0.1 mL.

Frequently asked questions
What is bacteriostatic water?
Bacteriostatic water is sterile, non-pyrogenic water with 0.9% (9 mg/mL) benzyl alcohol added as a preservative. The benzyl alcohol suppresses microbial growth, which is what lets a multi-dose vial be re-entered for repeated draws. In the laboratory it is the standard diluent used to reconstitute lyophilized research peptides into solution. It is a consumable, not a research compound itself.
What sizes and prices do you stock?
Single vials: 10 mL for $15 and 3 mL for $10, both US-FL stock that ships domestically. Kits of 10 vials: the 10 mL 10-pack is $100 and the 3 mL 10-pack is $60, both shipped from the overseas facility.
Do I need a prescription or account to order?
No account or sign-up is required to check out. Bacteriostatic water is sold here strictly as a laboratory consumable for research use only, alongside research compounds, and is not described for any human or veterinary use.
How long does bacteriostatic water last once opened?
Unopened, it lasts until the printed expiry, commonly two to three years. Once the stopper is first punctured, the standard multi-dose beyond-use convention is about 28 days, after which the vial is discarded regardless of remaining volume. This is lab consumable hygiene, not a human dosing cadence. See how long bacteriostatic water lasts for the full breakdown.
Bacteriostatic water vs sterile water — what's the difference?
The only substantive difference is the preservative. Sterile Water for Injection has no preservative and is single-use. Bacteriostatic water is that same sterile water plus 0.9% benzyl alcohol, which makes it a multi-dose container that tolerates repeated draws for aliquoting. More in bacteriostatic vs sterile water.
