If this holds up and is neither an error, nor related to medicine he is taking for his degenerative hip disorder (which seems unlikely for testosterone), it will be very sad news indeed about Floyd Landis’s recent Tour de France win:

As a financial aside, and not to be overly crass about it, but Phonak’s (Landis’s team sponsor) stock (PHBN.SW) has not yet responded to the news, even though it climbed nicely around his win.
[Update] As reflected in comments to this post, and elsewhere, there are reasons to be skeptical of the test result, if you’re of a charitable frame of mine.
