Hi, you can get the nrg-3 rock crystals at http://www.researchchemicalsexpress....rocks-22-c.asp. I don't really recommend it, the high's not great and I've descended in to rampant paranoia a few times.
Just read your message today. Thanks for info. Little leery of mixing AMT and other stuff. Still have a gm I bought in '02. It has been on scheduled list for a while here in US.
