Bacteriostatic water (BAC water) is sterile water preserved with 0.9% benzyl alcohol — the industry-standard diluent for reconstituting lyophilized (freeze-dried) peptides and research compounds in laboratory settings. The benzyl alcohol acts as a bacteriostatic agent, inhibiting microbial growth and allowing the solution to remain stable after initial opening, which is important for multi-draw research vials. Unlike plain sterile water, it resists contamination across repeated draw cycles, is chemically inert toward standard peptide compounds, and is used across research disciplines from endocrinology and peptide biology to pharmacology. myPEPT supplies bacteriostatic water in clearly labeled, sealed vials at research-grade standard, each batch verified for sterility and benzyl alcohol concentration, and ships across the EU with the documentation needed for lab intake. This product is a laboratory diluent supplied strictly for research use only — not for human consumption or injection; always follow your institution's protocols when handling sterile materials.
