well, it sounds like it all depends on the cleansing thing.... I have passed a test with nothing but niacin, exersise, and vitamin b12... and lots of water of course....

If u drink enough water, the percentage of actual urine in it is very low... since you didnt drink that much right before the test, that doesnt matter. Pissing 10 times before the test is definately good.

Post what kind of cleanser and maybe someone who knows the brands can tell u
