Ah you miss my point... sure the contamination could have come from a transfusion of stored blood. My point is he didn't actively, knowingly ingest clenbuterol during the tour. With me?
Oh, and re: the plasticisers. Whether its true or not is irrevelant I think to WADA or UCI. I understand the testing for them is not agreed? So it can't have any bearing on Contador's case. Not saying he didn't contaminate himself this way but rather it will not hang him!
Not according to WADA director general David Howman-
He also claimed that the World Anti-Doping Agency has not validated a method for detecting plastic from blood transfusion bags. This was contradicted by Howman, who said that a method was "fully validated and has been used in the food industry for years.”
“Its use for anti-doping purposes is partially validated and evidence from it, among others, can be used before tribunals.”
