Subbing Dilemma...

I've been reading hundreds of posts about beating the test and I realized that subbing is by far the best option, as quitting for even 2 months won't guarantee a clean sample for a daily smoker.

I have a dilemma for which type of sample to bring to the test though. A friend of mine who is clean has agreed to give me his sample, but he takes Advil/Tylenol a few times a week so I am concerned that this may set off a false positive.

On the other hand, I still have 10+ days until my test, so I have plenty of time to buy some QuickFix. Besides that one thread, I've read hundreds of successful sub stories with it and am quite confident that it would work. My test is at LabCorp and I've read specifically of users passing with QuickFix there.

I would rather use real human urine for the test, since I would be able to obtain more than just 2 oz that the QuickFix provides and just in case if there's a way that they could see that the sample is synthetic.

Any tips would be greatly appreciated...this site has already been an amazing resource for my research so far!

yea subbing is the best if you can

If your ABSOLUTELY sure your friend is clean his will work fine. If the advil happens to hit positive its no big thing. It'll show up as advil in the confirmation test. Lots of substances hit false positives, they just get sent to GC/MS to confirm what they are.
