What is Bacteriostatic Water?
Bacteriostatic Water for Injection is sterile water preserved with 0.9% benzyl alcohol, formulated to inhibit bacterial growth in multi-dose vials. Unlike standard sterile water, the benzyl alcohol preservative prevents microbial contamination without introducing reactivity with most peptide compounds, making it the preferred reconstitution solvent for the vast majority of lyophilized research peptides. Each 10mL vial provides sufficient volume for multiple precise reconstitutions.
Why Bacteriostatic Water Matters
The choice of reconstitution solvent directly affects peptide stability, sterility, and research accuracy. Sterile water without preservative allows bacterial growth within hours of the septum being punctured. Bacteriostatic water's 0.9% benzyl alcohol inhibits this growth for up to 28 days at refrigerated temperatures, enabling consistent dosing across research timelines.
Reconstitution Best Practices
- Use our Peptide Reconstitution Calculator to determine exact volume
- Allow solvent to run down the inside wall of the vial
- Swirl gently to dissolve; do not vortex or shake vigorously
- Store reconstituted peptides at 4°C; use within 28 days
- Use a new needle for each draw to maintain sterility
For research use only. Not for human or animal consumption.
This compound's precise mechanism continues to be characterized through ongoing preclinical research. Investigators have proposed interactions with growth factor signaling pathways, receptor modulation, and cellular repair cascades. Consult current peer-reviewed literature for the most up-to-date mechanistic hypotheses.
Store lyophilized powder at −20°C for up to 24 months. Once reconstituted with bacteriostatic water, store at 4°C and use within 28 days. Protect from light, moisture, and repeated freeze-thaw cycles. Handle in a clean laboratory environment with appropriate PPE. For research use only, not for human or animal administration.
Use our Peptide Reconstitution Calculator to determine the exact volume of bacteriostatic water to add. Allow the solvent to run down the inside of the vial slowly, do not inject directly onto the lyophilized cake. Swirl gently; do not shake. The solution should appear clear to slightly opalescent.
Orders ship in discreet, unmarked packaging with no reference to Aeternum Labs on the exterior. All shipments include full tracking and are insured against loss or damage. Most orders are dispatched within 1 to 2 business days. Cold-chain packaging is included where required to maintain compound integrity during transit.
