I had smoked daily for over 40 years and only had 10 days to get clean for a urine experimentation. I quick smoking two days prior to starting the 7 day detox and am very happy to report I experimented clean for a new job on the 10th day. I bought the second bottle of experimentation Clean just in case I am surprised with another toxin experimentation. All I can say is THANK YOU very much. Your product is amazing. Sandy
