From what I have read those cleansers are a waste of money, you really can't get thc out of your system at a fast pace. Basically your whole goal is to trick the test not pass it. I recommend drinking a lot cranberry juice and water, and take some vitamins to make sure the urine is yellow. The cleaner that you purchased probably works in the same fashion by tricking the test by dilution. You should be alright as long as you follow instructions but results are not guaranteed.
