Zaun made a pretty good point that the substance has a fairly short shelf life in the body, so the fact that Cola showed up to ST with it in his system suggests he either took something without knowing (stupid) or got something else that was "tainted" (s***** break). I mean, it's always possible that Cola just took it and come what may, but the other possibilities make it tough to just call him a cheat at this point.
And this is just me, but even if he did cheat (and yeah, cheating sucks), it's pretty understandable. The big leagues are pretty f***in' cutthroat if you're not a core guy. I wouldn't want to find a real job if I grew up dreaming about baseball. It's one thing for A-Rod and Braun to do it (scummy), but a guy who may as well be living paycheck-to-paycheck... a bit more understandable.
