What is bacteriostatic water?
Sterile water with a preservative that keeps a mixed vial usable for a few weeks.
Bacteriostatic water is sterile water with a small amount of preservative added. The preservative is what lets a reconstituted vial stay usable for a few weeks instead of being a single use mix.
People compare it most often to plain sterile water and saline, which lack that preservative. The 'bacteriostatic' part just means it slows bacterial growth, which is why it is the liquid commonly referenced for multi-dose vials.
TRKD+ explains what bacteriostatic water is so the label makes sense to you. It does not tell you what to use or how much. Questions about your own vial belong with a licensed provider or pharmacist.
