Does the stuff at GNC really help you pass a urine test?

My friend told me to go to GNC and get a detoxifying formula to flush out all the pot from my system. The guy told me to get Strip NC Natural Cleanser and buy Vitamin C. The Vitamin C are 1000 MG. He told me to start taking 2 every day, then the day of the test take 6 vitamin C in the morning right when I wake up, and then take an additional 6 more vitamin C an hour before the test. I already took my six, so I will then follow instructions actually how the guy told me to do. He says if they find a lot of vitamin C, just say I ate a lot of oranges or something. Then I have to take power Strip NC, and this will flush all the pot out of my system. I was planning on buying a drug test kit at my local Walgreen's to give me a heads up, so I know if I will pass. I also heard a Vitamin called Niacin or B-12 changes your Urine back to yellow after you drink tons of water. Should I drink like to gallons today and take that Vitamin that changes my Urine back to yellow?

no, no, no, nothing will help you pass a urine test but time. depending on what it is that your body needs to rid itself of. 30 days abstinance will do the trick for most substances.

Reply:I do not know where your buddy is getting all this information because he is wrong you will not pass and there is nothing in the world that would flush out your system of drugs.
Reply:What drug are you trying to flush out? A steroid, legal mass builder, or just illegal drug?
Reply:The quick flush that they sell at GNC work for a drug test that's going to be done right there with the test stick, that's when they put the stick in your urine, at the place. If they have to send it away to a lab, it's not going to pass, because the lab test for everything there is, and the lab can tell if you tryed to flush your urine. Good Luck!!! Drink alot of water and cranberry juice, If you really want the job just stop using for a while.
Reply:i am not sure about the vitamin c but read the label and do not take too much because you could harm or even kill yourself...as for the water do not guzzle 2 gallons of water (drink it slowly over the course of a day or 2) you could get sick and die of water poisoning (there was a news story of a woman dying around Christmas time last year because she drank close to 2 gallons of water you can google it if you do not believe me) too much of anything has the potential to harm you...i hope you can get the weed out of your system because it is really stupid that marijuana is illegal and companies will not hire you because you smoke it in your free time!!!
Reply:Apparently if you use them 100% perfectly accornding to the directions, they work.
Reply:No, you will lose. I used to work at a lab that checks for all the latest products.
