Everyone should listen to Real Peloton episode 29, a Contador special. Great work. Includes a summary of all dodgy stuff he may have been involved in all the way back to 16, when he first worked with Manolo Saiz. Similar Armstrong thing too, whereby it is hypothesised his brain injury may have been caused by thickening of the blood caused by doping. A must listen.
