About This Product
Bacteriostatic Water: The Reconstitution Standard for Research Peptides
Not Just Water
Bacteriostatic water is sterile water for injection containing 0.9% benzyl alcohol as a bacteriostatic preservative. The benzyl alcohol concentration is precisely chosen: sufficient to inhibit microbial growth in reconstituted solutions across multiple draw events, but low enough to be compatible with most research peptide formulations. It is the reconstitution solvent specified in the majority of lyophilized peptide protocols, and its absence from a lab supply chain is a significant research bottleneck.
BW vs WFI vs Sterile Saline
Water for injection (WFI) is preservative-free. Once a vial is punctured, it offers no bacteriostatic protection. Reconstituted peptides in WFI must typically be used within 24 hours. Bacteriostatic water extends the usable window of a reconstituted peptide vial to 28 days at refrigerated storage, allowing multi-draw use from a single vial across a research study period. Sterile saline (0.9% NaCl) is sometimes used as an alternative diluent, but it lacks the bacteriostatic preservative property and is appropriate primarily for immediate single-use dilution only.
Reconstitution Protocol Notes
For water-soluble peptides (CJC-1295, Ipamorelin, BPC-157, HGH 191AA, TB-500), bacteriostatic water is the standard first-choice solvent. Acetic acid 0.6% is specified for acid-preferring peptides such as GLP-1 analogs. IGF-1 LR3 protocols typically call for a small amount of acetic acid followed by dilution with BW. Researchers should inject solvent down the inner wall of the vial, not directly onto the lyophilized cake, to avoid mechanical peptide degradation.
Research Applications
- Peptide reconstitution: primary solvent for water-soluble lyophilized research compounds
- Multi-draw vial management: 28-day usable window at 4°C with aseptic technique
- Serial dilution: preparation of working concentrations from reconstituted stock solutions
- Formulation research: carrier solution for comparative pharmacokinetic studies
Quality Standards
- Analytical status: currently undergoing independent third-party analysis (Janoshik Analytical); the Certificate of Analysis is published at /lab-results once verification completes
- Form: lyophilized powder in sterile vials
- Storage: refrigerated for near-term use, minus 20 degrees Celsius for long-term storage

Research Context for Bacteriostatic Water - Add-On
Research Reagent Context
Reconstitution and handling supplies are the supporting reagents that make peptide research reproducible. Bacteriostatic water for multi-dose vials, acetic acid dilutions for compounds that require acidic buffering, and related reagents ensure the integrity of the research peptide they accompany.
Bacteriostatic Water - Add-On ships as a lyophilized research reagent through the LyzeLabs™ catalog in the Research Supplies category, available as a single research-grade format. Verified LyzeLabs compounds publish their full HPLC chromatogram and mass spectrometry confirmation, matched to the lot number on the vial, on the LyzeLabs lab results page; this compound's analytical data is published there as it completes verification.
