Get distilled water from Walmart
Boil it, once it cools down a bit draw 10ml and dump it into a sterile vial.
Add 9 units on insulin syringe of BA to it...
You now have BAC water.
I know GnT from another board he is a good guy I ordered the multi dose vial adapter works great and I’m waiting to see if its reusable when done with this vial.
