There is an answer to every one of your questions.
Mgmt is way, way ahead of any questions we might ask and every patent that we have will soon be understood differently and renewed as we further understand the science.
In your head, you think that simply adding a compound to water exposes us to copycats.
In reality, things are much, much different under the new mgmt.
Things will become clear in time. Just understand that as the MOA is further understood, the tighter the patents become and the more wrong the haters/doubter become.
"Purity" has nothing to do with this. In fact, its ignorance that will continue to pretend that the "purity" is what makes our science strong.
