...Body Guard Works, the detox drink is crap. Schizferatu is full of shit. I have used Body Guard my self and passed. You just have to know how to take them...(4) tablets in the morning and (4) in the late afternoon...do this for a week to (10) days before the test...you must stay clean that whole time and everything should be fine...I don't know what the big deal is with maryJane, alcohol is much worse for you. I have never gotten a bad head after a hogleg...
