Bacteriostatic Water questions, answered
- 01
What is bacteriostatic water and how is it different from sterile water?
Bacteriostatic water is sterile water containing 0.9% benzyl alcohol, which suppresses bacterial growth and allows a vial to be drawn from multiple times over the course of a study. Plain sterile water contains no preservative and is intended for single use.
- 02
How much bacteriostatic water do I need to reconstitute a peptide?
It depends on the vial size and the concentration your protocol calls for. Our reconstitution calculator does the math instantly, and the reconstitution guide covers technique — add the diluent slowly and swirl, never shake.
- 03
How long can a bacteriostatic water vial be used after first puncture?
The convention followed by most laboratories is a 28-day in-use window after the first draw, with the vial kept capped and stored per its label. Discard the vial if the solution ever appears cloudy or discolored.
- 04
Which peptides is bacteriostatic water used with?
Essentially every lyophilized peptide in the catalog — from BPC-157 to retatrutide — is commonly reconstituted with bacteriostatic water. Find it alongside other consumables in lab essentials.
