I am having the same problem! Does anyone know of a lab that does silicone testing in the US? Can one of you who has had the test done look at your results papers and see the name of the lab that did it? I have googled and googled, and can't find any online lab test site that offers it. Needless to say, my local lab told my doc that there is no such test.
One other thing I wanted to point out: my muscle testing doc also uses Standard Process products, and I have learned that some (not all, mind you, but some) of their products can be purchased online on Amazon. You might also want to check eBay, if you're looking to do this detox with SP products. There is also a health food store here in town that sells them (apparently they have some sort of "health care professional" on staff who can order them), but again, they don't carry as full a complement of these supps as my doc who deals almost exclusively in them. I consider myself lucky to have found the "suppliers" around here that I have, as they are good products. Also, naturopaths aren't the only ones who may have them, so you might want to expand your search beyond just NDs. The two docs in my town who carry them both do Nutritional Response Testing; one is also a chiropractor, and the other is also a psychologist. Hope this helps somebody!
