SERIOUS Help passing a drug test

Hey guys I am in some shit and I need you guys' help.....

So I have a drug test coming up soon for my dream job and it will certainley change my life if I pass this test...I have already signed the offer letter and I just have to pass this drug test.....

I have been clean little bit less than 2 weeks but I just know I won't be clean when I get tested so I have been doing tons of research and talked to a lot of people and it seems to me that I have two options left....

First...I have gotten quickfix 5.7 not the candian version and have seriosuly thought about using however although reviews are great there is always that few failing stories and I am terrified to use it because of it...and there always that chance of getting unluncky and getting it shipped out to some unlucky state in west coast...my job is in west coast but I will be getting tested in northeast

Second...I have seriously thought about using my friends clean urine..my plan is to clean out the bottle that comes in the quickfix and hve my friend piss in it like 20 minutes before I drive to the lab and apply the heating pad and hope it falls in the right temperature....but I am worried about is that the PH level and the urine going bad and stuff...I heard that I have two hour window before the urine's integreity goes bad and I am afraid it might cause some problems...

I have been not able to sleep nor eat this past week and any help would be amazing for me and thank you guys so much and please help a fellow out....
