I just passed a drug test using the dilution method elsewhere on this site, also drank some of the mega-clean 2 hours before, worked like a charm. I was a heavy smoker. 210lb, 35 years old. slow metabolism. I was clean for only 11 days. Drank detox teas up to the night before the test. Start the creatine 3 days early and do the vit b. What have you got to lose?
