What Bacteriostatic Water is

Reconstitution diluent, plain

Sterile water with a tiny bit of preservative, so a vial can be opened more than once.

Not a peptide. The thing you mix peptides with.

This is the boring-but-essential one: bacteriostatic water is just sterile water with a small amount of preservative.

That preservative, benzyl alcohol at 0.9%, is what makes it bacteriostatic, meaning it holds bacterial growth in check so a vial can be accessed more than once over time. It's the standard diluent researchers use to reconstitute lyophilized (freeze-dried) compounds like BPC-157.

It lives in Accessories because it isn't a compound on its own, it's what the compounds get mixed with.

What it actually is

Plain sterile water is single-use: once you draw from it, it isn't sterile anymore. Bacteriostatic water adds a small amount of benzyl alcohol so the same vial can be used over a longer window in a research setting.

That is the entire job. It is a diluent, nothing more, and nothing on this page is a medical claim.

How it's used in the lab

Reconstitution just means adding liquid to a freeze-dried powder to get it back into solution. Background on bacteriostatic water and benzyl alcohol is easy to find on PubMed.

Holds up over time

The preservative is what allows multi-use access.

Pairs with everything

The standard match for the lyophilized compounds on the shelf.

Research only

A research diluent. Not for human consumption.

Not exciting, but nothing else works without it.

What is Bacteriostatic Water?
Bacteriostatic Water is sterile water containing 0.9% benzyl alcohol, used as a diluent to reconstitute lyophilized research compounds. It is not a peptide. Sold for research use only.
Why does it contain benzyl alcohol?
The 0.9% benzyl alcohol is a preservative that holds bacterial growth in check, which is what allows a reconstituted vial to be accessed more than once over time.
Can the vial be used more than once?
Yes. Unlike plain sterile water, the preservative in bacteriostatic water allows a reconstituted vial to be used over a longer window in a research setting.
Does it come with a COA?
Yes. The batch ships with its Certificate of Analysis, shown on the product page.
What does "research use only" mean?
It means this product is intended strictly for laboratory research. It is not for human or animal consumption, and nothing on this page is a medical or therapeutic claim.

Not for human consumption. Not approved by Health Canada. For in vitro research only.
