I know for a fact that sur-gel does in fact work. Not only for pot either. Sur-gel helped me pass a state probation drug test after a gram and a quarter were consumed the night before. The process is simple. Mix it up, drink it about an hour before the test, drink water pee twice (or until clear) take your test. I've heard rumors about taking vitamin b and c to change the color of your piss, but honestly who cares what color your piss is? So i drink alot of water and my piss is clear, big deal. This exact method has worked for me and several friends in the past.
I actually had a test today that I'm a little concerned about though. I had an interview this morning at 10:30, so i stopped by the store on the way and got all my stuff. Drank the mixture at around 9:30 or so, but the interview process took forever. I didnt arrive at the clinic until about 1pm. I'm a little worried that too much time may have passed. If anyone has any information on how long Sur-gel stays effective please post. I get my results in a couple of days, and I'll pass along what i learn.
