i did wonder about what the proprietary system is whereby they concoct this stuff. and rather a lack of much data on it. anyway, I just bought some. Fortunately the smallest size, so we'll see what we will see. I am sure there is some good reason for my having done so. For some reason it tested strong for me. When that occurs it isn't always for the reasons one might imagine. I am open-minded enough these days that I am aware there could be untold reasons for me to cross paths with this substance. it's all good!
