I can't vote yet. I've believed he was clean in the past. I don't believe he used something so old school and detectable during the Tour when there's apparently so much other stuff you can micro dose and get away with, like the Lithuanian U23 guys a year ago.
I've read what the experts have said, including the revised opinion of Don Catlin (after he saw the actual numbers). No one thinks he consumed this during the Tour as a method of doping. The consensus is that it's the result of something tainted. The problem is that one of the things that could have been tainted was his own blood. I don't know. If he did have that boost, I don't know why he would have su.cked so bad in the Time Trial, unless he got really lazy with his pre-Tour training. But one bad day doesn't rule out anything.
Right now I've got an open mind. I'd like to see someone hit up Astana for the steak invoice. I'd like to see someone slip over to the butcher shop and get some meat samples, just for the heck of it, in case the practice applies to whole herds. But mostly I want some trustworthy scientists independent of the UCI administration to take a good look at all of Contador's samples for the year, really scrutinize them, and see if it looks like he added some blood on the rest day. This is a huge thing for the sport, and the world is watching. Bring in Dr. Morkeberg, Ashenden, Catlin, and experts I've never heard of. Put them in the best lab available, and let them hash it out.
