Do not believe any of the claims of this company. I followed everything they directed and even had 10 days with no toxins before I even started the program. They claim that all you need to do is go for 2 days with no toxins and follow the program and you will test clean. DO NOT BELIEVE IT!!! They will play on your fears, take your money and laugh all the way to the bank while you test dirty. They won't return e-mails or phone calls either. Save your money and do not give them a thing. IT DOES NOT WORK!!!
