Whoo! First post! Either way I feel I am qualified in the testing field to field this one...

Those detox drinks don't really do much themselves. Notice on them it says to drink an ungodly amount of water before and after. Basically not trying to be mean but you could do that with just drinking water. The drinking water part is what they call dilution, so the drink itself is filled with B vitamins and others to help recolor your urine (even though it usually ends up neon yellow). Hence its not the detox drink that cleans you out but the actual flooding your system with water.

BTW dilution is not a sure fire way to pass a test either. My advice to you if you are tested much is to get QuickFix or another synthetic urine.

Hope this helps man.
peace
