I don't know the science behind this, I assume the folks at the lab will explain what happened and why Braun's argument is or is not valid.
If that doesn't work, Braun would have to prove that food or supplements he was taken was tampered with by someone else without his knowledge. Baseball has a strict liability policy, meaning that not knowing something you were taking had a bad substance is no excuse, you have to show you were not carelessly consuming stuff without knowing what is in it. The only way to successfully appeal, aside from attacking the test result, is to basically prove that someone spiked your food. Good luck with that argument.
He's basically going to have to resort to the same arguments that every other athlete who's ever gotten caught with high testosterone uses. It usually doesn't work out.
