Spain presses for clenbuterol threshold

Spain presses for clenbuterol threshold: "The Spanish cycling community is clamoring for the introduction of a minimum threshold for clenbuterol in the wake of the highly divisive doping case involving star rider Alberto Contador.

One of the tenets of Contador’s defense is that testing technology has moved faster than anti-doping rules and that a minimum threshold should be introduced for clenbuterol to differentiate between levels that enhance performance and what they call false positives triggered by food contamination.

“There needs to be a change in the anti-doping standards,” Contador said at a press conference at the Volta ao Algarve. “Technology has advanced, but the rules haven’t. The rules should be in accordance and I believe that they have to revise some points in the short term.”

Contador’s lawyers say new testing methodology allows minute traces of clenbuterol to be detected – 50 picograms in Contador’s case – levels they argue are well below what would create performance enhancement."
