Perhaps.That white powder has been tested hundreds if not thousands of times, there's a whole industry that sprung up around testing those white powders.
Meanwhile, there's like a single 3rd party test of Bac water?
Not the same thing.
All that being said, I use the untested ASC bac water cause i'm not a bitch.
Maybe the tests are the same batch of white powder. Maybe they aren’t. It is what it is.
