chibi, to start, there is NO product that will remove THC from fat cells where it is stored, so NO product, reguardless of its claims will detoxify THC. There are 2 ways to defeat urine test. 1 is to substitute a clean sample. 2 is to dilute your urine to a point that the THC in it is below cutoff levels. Substitution, for non observed test is 100% effective. Dilution becomes more effective the longer you abstain. With my personal levels of toxins, I must abstain a minimum of 6-7 days before I can dilute enough to pass a UA, but every one is differant. Save your money on the 'magic potions' and use it insted for the supplies needed to dilute or buy clean substitute urine. Hope that helps. N2
