Bacteriostatic Water (BAC Water) — Research Reconstitution Solvent
Bacteriostatic Water (BAC Water) is sterile water containing 0.9% benzyl alcohol as a bacteriostatic preservative — the essential solvent for reconstituting and storing multi-dose research peptide vials. Unlike plain sterile water (single-use only), BAC Water’s benzyl alcohol preservative maintains sterility across multiple needle entries and extends reconstituted peptide solution stability for up to 28–30 days when refrigerated.
Available Formats

Why Bacteriostatic Water is Essential
🔬 Multi-Use Sterility
BAC Water’s 0.9% benzyl alcohol preservative prevents bacterial growth after needle penetration — enabling safe multi-dose use from a single vial over 28–30 days. Critical for research protocols requiring repeated draws from reconstituted peptide vials.
⏱️ Extended Solution Stability
Most peptide research solutions reconstituted in BAC Water remain stable for 4–6 weeks when refrigerated — significantly longer than sterile water reconstitutions. This stability is essential for longitudinal research protocols.
✅ The Research Standard
BAC Water is the recommended diluent for the vast majority of research peptides including all GLP-1 agonists, GHRPs, GHRH analogues, healing peptides, and anti-aging compounds. For any peptide used in multi-dose research, BAC Water is not optional — it is the research standard.
