Bacteriostatic Water — Laboratory Reconstitution Solvent
High-quality sterile bacteriostatic water formulated for reconstituting lyophilized research compounds. Contains 0.9% benzyl alcohol as a bacteriostatic preservative agent, enabling multi-use applications while maintaining sterility throughout the product’s shelf life.
Product Details:
Bacteriostatic water is an essential laboratory supply for researchers working with lyophilized peptides and other research compounds. The benzyl alcohol preservative inhibits microbial growth, allowing the vial to be used for multiple withdrawals over an extended period — a significant advantage over single-use sterile water for injection.
The borosilicate glass vial (Type I, DIN ISO 3585) provides excellent chemical resistance and thermal stability, while the brombutyl rubber stopper ensures reliable sealing even after repeated needle punctures.

This product is a laboratory consumable intended for reconstitution of lyophilized research compounds. Not for human or veterinary use.
Frequently asked questions
Peptides are sold as research compounds for laboratory and research purposes and do not require a prescription. You can order freely.
Lyophilized peptides should be stored at -20°C or lower for long-term storage. For optimal preservation, store at -80°C if available. Keep peptides in their original sealed vials away from light, moisture, and temperature fluctuations.
Important tips:
- Allow vials to reach room temperature in a desiccator before opening to prevent moisture absorption
- Avoid repeated freeze-thaw cycles - only remove from freezer when ready to use
- Store in airtight containers with desiccant packs to prevent moisture exposure
- Keep away from direct light - use amber vials or wrap in aluminum foil
- Properly stored lyophilized peptides can remain stable for 2-4 years
Once reconstituted with bacteriostatic water, peptides should be stored at 2-8°C (refrigerator) and used within 2-4 weeks for optimal potency. Some peptides may remain stable for up to 8 weeks when properly refrigerated.
Storage guidelines for reconstituted peptides:
- Refrigerator storage (2-8°C): 2-4 weeks recommended maximum
- Freezer storage (-20°C): Possible but not recommended due to freeze-thaw damage
- Peptides containing Met, Cys, or Trp have shorter shelf life due to oxidation
- Peptides containing Asn, Gln are more prone to degradation in solution
- Create multiple aliquots to avoid repeated freeze-thaw cycles if freezing is necessary
Note: We recommend using reconstituted peptides within 2 weeks when possible, as potency gradually decreases over time.
Always use bacteriostatic water (BAC water) containing 0.9% benzyl alcohol for reconstituting peptides intended for multiple doses. Bacteriostatic water prevents bacterial growth and maintains sterility over several weeks of use.
Water types comparison:
- Bacteriostatic Water (RECOMMENDED): Contains 0.9% benzyl alcohol preservative, multi-use safe, prevents contamination, stable for 28 days after first puncture
- Sterile Water: No preservative, single-use only, risk of contamination with multiple punctures, not recommended for peptides
- Tap Water (NEVER USE): Contains impurities, minerals, chlorine, bacteria - will destroy peptides and cause contamination
- Distilled/Boiled Water (NOT RECOMMENDED): Not sterile, lacks antimicrobial properties, risk of bacterial growth
Use this simple formula to calculate dosage:
Concentration = Total mg in vial ÷ Total ml of water added
Example calculation:
- You have: 5mg BPC-157 vial
- You add: 2ml bacteriostatic water
- Concentration: 5mg ÷ 2ml = 2.5mg/ml
- If your dose is 250mcg (0.25mg): 0.25mg ÷ 2.5mg/ml = 0.1ml (10 units on insulin syringe)
Common reconstitution volumes:
- 2mg vial + 2ml water = 1mg/ml concentration
- 5mg vial + 2ml water = 2.5mg/ml concentration
- 10mg vial + 2ml water = 5mg/ml concentration
Tip: Use our online peptide calculators or create a dosing chart when you reconstitute to avoid calculation errors.
