Why Choose Bacteriostatic Water
Bacteriostatic water contains 0.9% benzyl alcohol as a preservative, which inhibits bacterial growth and extends the shelf life of reconstituted peptides. This is particularly important for research studies requiring multiple dosing over several weeks.
Sterile Water vs. Bacteriostatic Water
While sterile water can be used for immediate single-use applications, bacteriostatic water offers several advantages:
- Extended stability: 14-28 days when properly refrigerated
- Reduced contamination risk during multi-dose studies
- Better pH buffering capacity
- Maintains peptide integrity longer
Proper Reconstitution Technique
Always inject bacteriostatic water slowly down the side of the vial to avoid creating foam or damaging the peptide structure. Allow the lyophilized powder to dissolve naturally without shaking or vortexing.
Volume Considerations
For most research applications, using 1-2 mL of bacteriostatic water per 1-5 mg of peptide provides appropriate concentration while maintaining stability. Calculate your desired concentration based on planned dosing frequency.
