Contador was unstoppable before he was caught,I think he did it for years before the scandal.But if I remember corectly Contador agreed he was guilty.
Cheers. Also taken from USADA policies on Clenbuterol: ''Clenbuterol is sometimes prescribed outside of the U.S. to treat asthma, and may be used in other countries to bulk up livestock. There is no threshold limit for clenbuterol, meaning the detection of any amount of clenbuterol in the sample is a positive test. Clenbuterol may also be found in some products marketed as dietary supplements, and may be publicized as a weight loss drug. Make sure to review the This content is protected Wonder how much Browne had in the system at the time and if it would determine how much he took and if it even would be beneficial (in terms of the tainted meat maybe ala the Mexico soccer team incident, it could be a 'lower/ unbeneficial' reading) or if a 'high' reading then maybe would indicate doping or 'spiking'. I think the Contador case, the amount was 40 times lower than a 'doping reading' but because of their no tolerance policy he got done. They also claimed tainted beef didnt they? Interesting...
