Somebody steered me to this site some time ago

http://www.asc-alchemy.com/mono.html

and they supposedly are true to the tradition of David Hudson.
As I've said, I know next to nothing about this whole process
but they claim on their site, the following...

"There is also some total hype "out there". We had a customer who put up a beautiful blue website ZP; copying information from credible sites and creating computer-generated "kirlian" (color corona/auric field) photographs, but fabricated black and white pictures with no real substance behind the words or photos. So along with good people motivated by sincere passion selling viable products you begin to get fabrication. Unfortunately at this point there is no real protocol for what people can call monatomic, diatomic, white powder gold, etc. One can sell water; literally a dropper bottle of water, and call them monatomic/diatomic elixirs. Various minerals certainly do contain some gold m-state and can be powdered and marketed as white powder gold. Most of you know it's silly to claim to sell pure white powder gold for $40.00 a gram; it would not be sold in this manner. But at this point there is simply no standardization. Our approach and focus is certainly not for everyone; if you don't connect with our approach we'll be glad to recommend someone who we have no affiliation with other then a shared passion for the field. Most are wonderful folks but you do need to use discrimination at this point."

As I say, I'm ignorant of the subject generally, but they don't
seem too enamoured of ZpTech...
that's why I'm curious to talk to someone who has a real living
experience of the products generally.
