Bacteriostatic Water

Bacteriostatic Water for Injection is sterile, non-pyrogenic water that contains 0.9% benzyl alcohol (9mg/mL) added as a bacteriostatic preservative.

The difference between bacteriostatic water and sterile water is that other sterile waters for injection do not contain a bacteriostatic agent. As such, they are single-dose vials and should be discarded after a single use.

Actually the best solvent due to the preservative agents to maintain purity, integrity and efficiently dissolves lyophilized aggregates. (HGH,HCG,Peptides..)
