Research use only. This is laboratory material. It is not an approved medicine in Canada, it is not for human or veterinary use, and nothing on this page is dosing or administration guidance.
The short version
- Bacteriostatic water is sterile water with 0.9% benzyl alcohol added as a preservative. The preservative is what lets a vial be entered more than once.
- It is the standard diluent for reconstituting lyophilized research peptides. It is not a peptide itself.
- We stock 10ml vials, singly or as a pair. A branded Pfizer/Hospira 30ml vial is sold separately.
- Ships from inside Canada with the rest of your order, so your peptides and the water arrive together.
- Free express shipping over $250.
What arrives
A sealed multi-dose glass vial of clear liquid with a rubber stopper and a flip-off cap. Unopened, it is stored at room temperature away from light. Once the stopper has been punctured it should be kept cold and used within the window printed on the label, because the preservative only holds for so long.

Shipping and payment
Orders leave from inside Canada, so nothing crosses a border and nothing gets held at customs. Express shipping is free over $250. Below that it is a flat rate shown at checkout. Payment is by Interac e-Transfer. Tracking is sent by email once the carrier has the parcel.
Where Bacteriostatic water stands in Canada
Bacteriostatic water is a laboratory diluent, not a medicine and not a peptide. Sold here for reconstituting research material. Most orders that need it add it to a peptide order so everything ships together; if you only need water, it ships on its own at the flat rate.
Questions people ask before buying Bacteriostatic water in Canada
Generic bacteriostatic water or the Pfizer/Hospira vial — what is the difference?
Same purpose. The Pfizer (formerly Hospira) product is a 30ml branded pharmaceutical vial; ours is a 10ml laboratory vial. People who want a recognised brand name on the label choose the Pfizer 30ml; people reconstituting one or two vials at a time usually choose the 10ml.
How much bacteriostatic water do I need?
It depends on the vial you are reconstituting and the concentration you want. The peptide calculator does the arithmetic for any vial size.
Can I buy bacteriostatic water in Canada without importing it?
Yes. Ours ships from inside Canada, so there is no customs step. Free express shipping over $250, flat rate below.

using the first vial right now – all is good. no complaints 🙂
It’s BAC water, nothing much to say. Arrived sealed and was pretty easy to use for reconstitution.
Great quality. Will buy this product again.
Company seems solid.
