Bacteriostatic water
Where a compounded drug parts company with an FDA-approved one, where 503A parts company with 503B, and which accreditation programs tell them apart.
What is Bacteriostatic water?
Sterile water preserved with 0.9% benzyl alcohol, used to turn lyophilized powder back into an injectable solution.
The preservative is what makes it safe to draw from the same vial repeatedly. If you are asked to mix your own medication, you have been handed a compounding step, and the strength you end up with depends entirely on how much water went in.
