Supplies

Bacteriostatic Water

Preserved water, for mixing lyophilised peptides.

What the research targets

A bench supply, not a research compound: sterile water with 0.9% benzyl alcohol, so one vial can be drawn from more than once.

Research use only

Supplied to qualified professionals and institutions for laboratory research. Not a drug, supplement or cosmetic, and not for human or veterinary use. We publish no dosing or administration guidance of any kind.
