BioWater has come up multiple times in threads on this board. A number of BAC suppliers — Medex, Farris Labs, Bacteriostaticwater, among others — are reselling it. Should you have purchased it already, or be considering doing so, my recommendation is that you go through the most recent piece written by "Some Lady" on her sub, which covers purity, sterility and the alcohol level of this BAC. Harm reduction is 1 of the central principles of this community, and this speaks directly to a key part of it.
