This substance is primarily used for the dissolution or dilution of medicines. The reason as to why it is referred to as bacteriostatic water is because the benzyl alcohol prevents bacteria growth, and allows a vial to be re-entered several times.
Bacteriostatic Water (BAC) plays a crucial role in the transmission of medicines intravenously, and even intramuscularly.

Bacteriostatic Water for Injection contains water for injection USP with 0.9% (v/v) benzyl alcohol as preservative. The benzyl alcohol bacteriostatic agent inhibits bacterial and fungal proliferation, enabling repeated aseptic withdrawal from a single 10 ml vial over an extended laboratory use period — a critical property for multi-dose peptide reconstitution protocols. BAC water is chemically inert with respect to most lyophilised peptides and proteins, making it the standard reconstitution medium for research compounds including BPC-157, TB-500, CJC-1295, Ipamorelin, and other injectable peptide formats. pH is maintained within a range compatible with peptide stability. American Peptides supplies BAC water in 10 ml multi-dose vials, sterile and sealed, for laboratory reconstitution applications. For research use only.
Every batch is independently lab tested for identity, purity and potency. View our lab testing program →
Why is bacteriostatic water preferred over sterile water for peptide reconstitution?
Bacteriostatic water contains 0.9% benzyl alcohol, which inhibits microbial proliferation following vial puncture. This enables multiple withdrawals from a single vial over the course of a research protocol without contamination risk. Sterile water for injection (without benzyl alcohol) is a single-use format — once punctured, microbial ingress risk increases with each subsequent withdrawal.
BAC water is the standard for multi-dose peptide reconstitution in laboratory settings.
What is the concentration of benzyl alcohol in American Peptides BAC water?
American Peptides Bacteriostatic Water contains 0.9% (v/v) benzyl alcohol as a bacteriostatic preservative. This concentration is the standard formulation for multi-dose research-grade reconstitution solutions.
How long can a reconstituted peptide solution prepared with BAC water be stored in laboratory conditions?
Storage duration for reconstituted peptide solutions depends on the specific peptide, concentration, and storage conditions. As a general laboratory guideline, most peptide solutions reconstituted in BAC water and stored at 4°C remain stable for 4–6 weeks. For longer-term storage, reconstituted solutions are typically aliquoted and stored at −20°C. Researchers should establish stability windows per compound using established SOPs.

American Peptides has the best customer service in this industry. I honestly did not receive the first delivery even though the tracking showed delivered. No questions asked they re-shipped a second shipment to me and they filed claim with the Post Office and absorbed the frustration.
