I googled "testosterone/epitestosterone" and found an article that talks about drinking alcohol increasing testosterone levels. (I dismissed all articles from the general media and focused on peer review studies.) The way I figure it, he would have to drink 4.69 ounces of alcohol to increase the testosterone level. They are talking about pure alcohol, so 100 proof whiskey would be 9.38 ounces. Disclaimer - I did this from metric conversion charts on the web - if there is a scientist in the house, maybe she can check?

I couldn't find a direct link talking about how quickly injected testosterone clears the body, but most articles suggested that testosterone would need to be injected for at least 2 weeks to have any positive affect on performance. As was said previously (and forgotten quickly) just one shot of testosterone won't make him fly like he did in stage 17.
People need to quit getting their exercise by jumping to conclusions. This guy's career is on the line. We should know beyond a shadow of a doubt that he is guilty. Thus far, we don't.
