What is BAC Water?
A laboratory reconstitution vehicle: sterile water preserved with benzyl alcohol. Not a peptide and not a drug product.
Research use only. Not for human or veterinary use.

BAC Water
3 ML
Overview
Research catalogs list bacteriostatic water as a companion solvent for reconstituting lyophilized reagents in the hood. Composition is water plus a stated percentage of benzyl alcohol — confirm the lot label. This is not bacteriostatic sodium chloride, and it is not a protocol for preparing injections for people or animals.
Research areas
Framed as published laboratory and clinical literature. Not treatment guidance.
Laboratory reconstitution
Used as a documented vehicle when an assay SOP calls for a preserved aqueous diluent. Follow institutional sterile-technique rules and the peptide lot paperwork.
Storage & handling
Store sealed at controlled room temperature or as stated on the vial. Do not use a container that has lost sterility indicators.
