[Discussion] mg/mL is doing more work than we give it credit for
Something I keep coming back to: mg/mL is doing more work than we give it credit for. Bacteriostatic water contains benzyl alcohol as a preservative, which is what makes repeated entry into the same vial reasonable. Plain sterile water has no preservative.
