I have called several times worrying about the fact I had passed a THC experimentation at a clinic last Friday after completing 9 days of Toxin Rid, but was failing all my home self-experimentation since then leading up to my pre-employment screening. It turns out, the experimentation I was using, which were 12 for $13 on Amazon prime, didn’t work.They look identical to the one you provide, except they are the “easy@home” brand. If you get any more calls from people completing the Toxin-Rid program, and still not passing home screenings, please ask them what kind of home experimentation kit they are using. The $19 kits at Walgreens work very well, and the ones your company provides work as well. The cheap knock-off brand I was using can’t be trusted.
