You cannot buy it anywhere. It is very simple, however it requires a relatively high level of skill. You can look up Dr. Koch's patents from the US, Canada, and UK if you read them all against the backdrop of his other writings, you can see the evolution of his thesis. He actually describes in his writings all that is needed to be known. It is a huge time investment, but well worth it, very fascinating. Unlike what some call it homeopathy, it is not homeopathy. People who call it that only show their ignorance. A single injection is all it takes in most cases, if the person is first properly prepared, the recovery has a periodicity to it, all these and more are described in his writings. I judge it impossible to undertake unless one has at least one years equivalent of college organic chemistry and some lab prep experience. It is totally F'n amazing !!!! The best route is using fructose, phosphoric acid and P2O5 to get the high molecular weight serial system of conjugated carbonyl groups. I could write a book on this but fortunately I don't have to, Dr. Koch already wrote several. the remedy is non-isotonic, it hurts like a mfrkr for a few minutes
