Will creatine and beef protein or asprin help disolve alcohol in your urine?

No and like most other myths you can't speed up the process by eating big meals or exercising. I know you said dissolve but I am guessing you mean lowering the alcohol so a test will come back with a lower, better reading.

Definitely not, and don't try flushing your system with Niacin or anything stupid like that, you can get dangerously ill. Honestly, it will help your system, but it won't help you pass a test. Time is your friend on this one.
