This product did not work for me. I had to take a monthly drug screening for my probation, and quit more than long enough before starting the product. I even spent the extra money on the detox drink which did not help either. I have a receipt from my probation officer stating that I failed my drug test because of THC levels, which this product is supposed to help negate that. Going to try to get a refund because this product stated MONEY BACK GUARANTEE, but I'll be posting more on this on my review sites if the problem is not resolved. Thank you.
