my friend took that shit, and it fucked him up.... besides, why take a whole shit load of pill that turn you red and itchy and make you hot and sweat... go to
www.testnegative.com....they have everything from drinks to pills, to synthetic powder urine that you just mix with water, and it even has some shit to poor in that heats it up to the temp of inside of your body. i've used a few of there products with 100% results... you do have to not smoke 48 hours before your test, but thats better than a month to let your body naturally clean it out of your system. i used these products while on probation, and there test are the hardest, but i had no problems... if you just have a test for a job or some shit, then just buy the fake urine, because then you don't have to stop smoking at all....but if its because of trouble with the law, sometimes they whatch you so you can't cheat... and even know you will pass, just for piece of mind if you don't they give you %200 your money back, you pay 25 for pills, and pass, they send you a check for 50
