He's talking about using the sur gel method, some people swear by it and many have failed. It's about as reliable as a detox drink. If you are really serious about needing to pass this test don't take advise from someone who heard it from a friend of a friend. Next he'll be saying that Niacin cleans you out in 3 seconds and you shit rainbows afterwords

FBR already debunked surgel in one of the sticky's. If you have to take a drug test and you don't think you have a chance in hell of legitimately being clean on time then read the dilution or substitution sticky and decide which one is best for you. if the sticky's haven't answered all of your questions then feel free to post back
