other drinks are supposed to flush your system but testpure is said to mask the THC in the piss with vitamins,
Pure sales pitch designed to lure in the credulous and the uninformed. These potion peddlers need to spend more time researching how drug testing works and how THC is processed in the human body - and less time trying to promote their snake oil through the use of false info. Because if they had done their research, they would have learned that vitamins are used to add color to the urine - not masking THC metabolites. Color is the least aspect in determining a diluted sample anyway. Even samples with color to them can still fall below the acceptable limits for creatinine and specific gravity.

Its the water consumption involved with the magic potion that "masks" THC metabolites (via diluting the metabolite concentration present in the bladder so the sample tests below the cutoff limit of the drug screen). Testpure is no different from all of the other magic potions.
