Having read the ENTIRE report, I would at best say Andy was guilty of inquiring about a substance (HGH) that was legal for both the public and MLB at the time, and then took a few doses of it while recovering from injury, which was prescribed by a physician. However, there is absolutely no hard evidence of this, only hearsay testimony.
HGH has been peddled to the public for years as a "fountain of youth" and you can still buy it- though its value is disputed by physicians, most say it doesn't do much of anything. At the time he took it for his recovery from elbow problems, IT WAS NOT a banned substance in MLB.
Plus, the accuracy of the Mitchell report is already suspect, so the possibility exists that it never happened. I don't necessarily buy that, but I don't trust the report 100%, either.
I'm not saying what he did was right, but knowing what I know of Andy and the situation, he is not a habitual user or abuser of any banned substances, nor was he ever.
So don't feel bad, and keep rooting for him. Clemens, Bonds, and Sosa, well.... that's a different story.
EDIT: For "beast" above- can't tell you names, but I have 4 good friends and another 8 or so aquaintances that work for various teams in the front office or as scouts. The dirty little secret of this whole report is how everyone seemed to know who was using (check the scouting reports in the report) and some teams, like the Dodgers, knew that they were dealing "damaged goods" to teams like the Yanks, Mets, etc, etc.
I DO find it suspicious that the Red Sox seemed to have such inside info on who was/wasn't using, and that almost no current/recent/former Sox were named- however this report is far from exhaustive and should NOT be treated as gospel verse in any way- it's full of more holes than swiss cheese!
