Bacteriostatic Preservation for Multi-Use Peptide Reconstitution
Bacteriostatic water (BAC water) is sterile water for injection containing 0.9% benzyl alcohol as a preservative. The benzyl alcohol inhibits bacterial growth following needle puncture by disrupting bacterial cell membrane integrity and membrane-associated enzyme systems — allowing safe multiple draws from a single vial for up to 28 days when stored at 2–8°C. At 0.9% concentration, this bacteriostatic action occurs without causing peptide denaturation or precipitation — critical for preserving Epithalon, GHK-Cu, NAD+, BPC-157, TB-500, IGF-1 LR3, and SNAP-8 integrity across multi-day protocols. Regular sterile water has no preservative and is considered single-use only after puncture. pH is adjusted to 5.0–7.0, within the stability range of all standard peptides.
What ships on this SKU
Sterile water for injection with 0.9% benzyl alcohol in a 10mL multi-dose vial (pH 5.0–7.0). Volume, preservative percent, and shelf-life dating are printed on the carton and vial label.
After first puncture
Bacteriostatic water is intended for multiple withdrawals from one vial when stored at 2–8°C after opening; follow the printed beyond-use dating (28 days post-first puncture when refrigerated is typical—confirm on your label).
Cart note
Often ordered alongside lyophilized catalog SKUs so reconstitution solvent ships in the same supplier checkout as your peptides. Add it in the supplier cart if your protocol calls for preserved diluent.
