An argument can be made that this is not an enhancer at all. Some people suffer from an abnormally high level of adrenaline when they are under stress. Inderal takes them back to a more normal level of adrenaline. It does not make them stronger or faster. And in the case of a musician, it does not make him/her play any better than in rehearsal. My sense is that Inderal is benign and should be allowed. I am wondering what makes you think that it is bad. Have you seen musicians suffer and side effects?
Inderol is very popular with musicians and actors who suffer from "stage fright". I have never been able to determine whether it is a banned substance for purposes of MLB.
I may be totally wrong, but it seems to me that the As do a much better job developing players, especially pitchers, and that Beane is a very savvy trader.
I just used Ticket King and they were excellent -- better prices than StubHub. Also you get a 10% discount for using the TD promo code - DailyDouble. Also, the woman who I spoke with was helpful/adorable.
