JC Romero suspended

Former Twins pitcher J.C. Romero, now of the Phillies, was suspended for the first 50 games of the season after he tested positive for a banned substance. This specific instance raises particular issues.
First, as Twins fans are probably saying everywhere, he obviously wasn't using PEDs while he was in Minnesota. Sure could have used them.
Second, the andro detected in his system was from a supplement purchased at his local GNC. The Players Union apparently had this on the list of allowed supplements, and Romero was confused and took them. It doesn't sound like Romero was doing anything wrong and was a victim of misinformation, rather than trying to cheat his way to success. Should he be suspended?
Absolutely. If this was a problem, a widespread problem, why were he and Sergio Mitre the first to be suspended for this? Romero and Mitre, depite all the evidence that they were mislead, were exceptionally careless. Either they were the only players in the league to think of using this supplement, or they were the only ones to try it without vetting it with people more knowledgeable then they. If they are this reckless, they need to be reprimanded, and reprimanded severely so they and the rest of baseball gets the hint. You have to be in this for yourself.
