there was an article a couple days ago in the wall street journal where landis admitted to drinking 2 pints of beer and 3 shots of whisky the day before his come-back. Appearently there was a study unknown to landis that alcohol can increase your testoserone level anywhere from 30- 200%. I'm not going to make a call on whether or not he did it, but I thought that was an important piece of evidence to take into consideration.
