Drug test (what else)

Ok so ive been reading up on everything about beating drug tests. I thought i was learning more, but the more i read the more i get confused and really dont know what to do anymore.

The test ill be getting is most likely a cheap one from a drug store or an equivalent. So i read up on water B2 and creatine, Niacin, Niacinamide, and Nicontic acid. Also hiding a clean urine filed thing. I found hiding the urine to not be practical in my case because the test will most likely be random. The one that would be the most convenient would be the bleach method, although after some further research it seems that it doesn't work. Just wondering what the best method is for random (cheap) drug tests. because if bleach works i could hide some in all my bathrooms and that would be really easy. Thank you
