D420

I bought the product Vale, which im planning on using to pass a drug test later this week.

Ive been clean since tuesday and im expected the drug test on friday.
Since then I've been downing water regularly to the point where my urine is crystal clear (not that it means its cleaner) but in taking the vale product, what i would like to know is if once drank the detoxifying effects will last until i smoke pot again, or if im on a limited window, the product itself doesnt say anything about timespans of effectiveness, so if anybody could shed some like it would be greatly appreciated...

I've emailed the company with the same question, but im getting a bit nervous and would just like anybody elses input if possible, thanks
