I'm 6'3 240lbs and I don't exercise at all. My metabolism isn't great, and I've had a ****ty diet until recently. I've been a daily smoker for about a year and a half now, and I'll have gone about 15 days without smoking at the time of my test. My buddy works at GNC and got me this Zand 7-day body cleanse for free, so I tried it for the hell of it, and plan to test myself in the days before my test. Part of the cleanse involves drinking tons of water, so I've done that too.

My question is this: another buddy of mine passed a test using XXtra Clean, which supposedly isn't a flush but a "masking" agent instead. He bought it in a 3-pack, and is offering me one for free if I want to use it. I've obviously seen how much people on here hate on all the detox drinks and whatnot, and I have a lot of respect for that opinion because it seems valid and credible. But considering I dont have to pay for this ****, I'm thinkin of using it. I was just wondering if anyone's ever used it before, or knows anything about it that might help me out. Thanks in advance people...
