I Have To Pass This Drug Test

I'm currently in the process of getting a way better job and I will be drug tested.  I also have to pass this test, as my mom's friend is hooking me up with it.  It could be happen a week or two from now and I'm am just now quitting. 
 
So I want to use some fake urine or maybe some real urine to pass the test.  I've read about how sometimes they do a 'foam' check and some of the synthetic urine won't foam up and gets rejected.  I've also read about drug tests being a lot more up to date and can test for fake urine.  Are these things true?  If so, is there any products on the market that can still pass these things? 
 
Also I might could get someone's clean urine, but does it matter if it's a female when I'm a male?  Does anything else matter when using real urine? 
 
I've used the fake piss a few times in the past (over 5 yrs ago) and always passed but I'm worried about them being rejected in 2014 w/ all more sophisticated drug tests.  Let me know yall's advice and experiences. 

 

Does the quickfix foam up if shaken?  I haven't used a substitute for a drug test in many years, but I'm just worried about the newer drug tests, testing for sythetic. 

 

bump.
 
Does anyone know if it's true that they do a foam test, that normal synthetic urine wont pass? 

 

Thanks for the reply.  That's what I've always used, but I haven't used one in like 7 yrs or so.  I've just been hearing how drug tests are more and more up to date on things that could be used to help pass it. 
 
So when was the last time you took one?
