Whats The Best Way To Pass A Drug Test

I dont know why my last thread got deleted or moved, which is gay.  I know there is a drug testing sticky, but that thread is of no help.  You just tell a dude your smoking habits and he tells you if you can pass a test or not, and I dont need to know that I'm gonna fail my test.  So yeah, that thread is of no use to actually knowing whats the best current methods on the market to pass.
 
 
So I've heard (dont know how true it is) that the newer drug tests can detect if you are using synthetic urine and it must also pass a foam test.  So what are some current synthetic urine that will still pass these newer drug tests?  I've also seen real frozen urine or powder urine, how effective are these? 

Also, if I  use real urine from a friend, does it matter if they are female or male?  I am a male, btw.
