This product works. Have used it twice successfully. You must have two days clean time prior to use. Use on an empty stomach. Two hours before drug test drink the contents of the bottle. Fill the bottle back up with water and drink that as well. Drink at a comfortable pace. Make sure you urinate twice before your test. Your third urination will be into the cup for your drug test. It’s somewhat expensive and the taste isn’t great but who cares if you get that job or keep your freedom.
