Maryanne,
I was unaware of it until the baseball scandal which occured over the winter:

Apparently, this over the counter AI is supposed to increase testosterone by blocking estrogen. I guess he thought it would be a "work around" for the banned steriods, but it still triggered a positive test.
There is also an abstract from the current ASCO that discusses changes in body mass in women on AI's :
http://www.abstract.asco.org/AbstView_65_32202.html which I think would make these designer drugs in Hollywood. If the overall effect is to maximize a decrease in fat and an increase in lean body mass, this would help an athlete develop muscle power as well.
The scariest thing to me is that 6 OXO Extreme is out there at your local GNC and other vitamin stores with no FDA approval or control. Those of us who take these drugs know how powerful they are and can discuss side effects with our docs.
Hopeful
