The reason that you see so many different variations is because it is stored in your fat cells and everyone is so completely different that there is no sure way to clean out your system (including products that you can buy at GNC). The only 2 ways to pee clean is 1) stay clean or 2)substitution. Since substitution has always worked for me, that is the route that I take. You can use a friend's pee or a synthetic. I have never failed with quick fix which you can purchase at urineluck.com, or call them to find out if a store in your area sells it.

Good Luck
