The answer is NO!!!!!!!
No such detox kit in the world will really clean you out!!!
No matter what they say its not a cleaning agent its a masking agent. Ive been useing the so call detoxt kits for year and they will not clean you out but if you fallow the directions closely you will pass a simple drug test but if you were to be tested agian the next day with out using the stuff agian you will fail.
Trust me Ive lost a job this way and they would not refund my money at the store... lol (I was pissed)
By the way dont listen to anyone when the tell you take a bunch a niacin ether. You can possible die
