If you are going to use the "It wasn't supposed to be in the supplement" argument, there is a lot to prove The excuse Palmeiro used when he was caught was that he never intentionally took any product that he knew was a banned substance. The MLB along with NSF has an ever growing list of supplements that the players need to stay away from because of the risk of a false positive. NSF also certifies and sells products to teams which they have approved as not triggering a false positive. If a player finds a supplement that is not approved by NSF and is not on the list of banned supplements, it is up to the player to get approval through NSF before taking the supplement. In other words, there is almost no wiggle room for the "I unknowingly ingested a product that contained an exogenous testosterone" excuse. If Braun did take an NSF approved supplement with synthetic testosterone, he would need to have that supplement LOT number tested and come back positive in order to be exonerated. This would have surely already been done if that was the suspicion. There are too many conflicting reports to figure out what is really going on with Braun's samples at this point. Was it Braun's "B" sample that came back negative, or was it a completely different sample that came back negative. And if it was a new sample, what are the reasons for needing that second sample? Why has it taken so long to complete this process? When McGwire said he wasn't prepared to talk about the past, I laughed. When Sammy Sosa forgot english, I laughed. When Manny Ramirez took his vacation to Spain after the second failed test, I laughed. Now that Braun is put in a similar awkward position I can only hope that he is proven not guilty, but it certainly doesn't look good.
