I'll just let you know if I did it right when i find out I passed!
More info while I'm at it, I take Liverite everyday, not because of the drug test but because I drink and it is suppose to make the liver work better (which could aid in detox) Also the test is a "20" not a "50" cutoff, bad news but I passed one before.
I took fiber during the days that I knew the test was coming (I found out Wednesday the week before) to help clean out. Also I added Vitamin D 1000 IU starting Friday before the Monday to build up a fat soluble vitamin layer over the old fat.
Someone told me hypervitaminosis would help with drug test a long, time ago but I read the opposite lately, figured I'd do something similar anyway.
