However defense of Alberto Contador is likely to be plausible, many skeptic persons do not believe him

The professional cyclist Alberto Contador that won the 2010 Tour de France tested positive for Clenbuterol. Amounts of this substance in his body were very small. They were 40 times less than its minimum standard of the detection capacity. But the World Anti-Doping Agency lacks tolerance completely when it comes to this medication. Any quantity of this preparation uncovered in a sportsperson’s body leads to ban.
Alberto Contador proclaims that the positive for Clenbuterol is caused by meat contaminated with this substance. Many experts believe him, since the amount uncovered in his urine are very small.   Neveretheless, Alberto Contadorwas banned.
Douwe de Boer, anti-doping expert of Contador’s defense team, proclaims that he becomes disappointed in decisions of the WADA day by day. He notices that he seems as if the WADA enjoyed to ban innocent athletes but not to detect cheaters.
Zhao Jian of China’s Anti-Doping Agency proclaims that a person may test positive from contaminated meat. It isn’t just anyone’s point of view. This affirmation has scientific basis. The expert Detlef Thieme from Germany supports this statement too.  He points out that nobody can doubt about it.
The expert Wilhelm Schaenzer of the Laboratory for Doping Analysis from Germany notices that it is a real problem that they are not able to investigate and determine doping clearly.
According to anti-doping researches conducted in Cologne, it is more likely to detect Clenbuterol from contaminated meat than from intentional intake of this drug for athletic purposes.
China’s National Anti-Doping Laboratory reports that experiments conducted by them have shown that consumption of pork meat containing Clenbuterol may cause positives for this substance.
But there are skeptic people who assure that the cyclist Alberto contador has used forbidden medications.
Skeptic attitude to Alberto Contadot can be explained by the condition that use of EPO, anabolic steroids, HGH and other products which cause performance-enhancing effects is widespread in cycling. The former cyclists Floyd Landis and Bernhard Kohl that have been caught by the WADA claim that all cyclists use performance-enhancing drugs. Patrick Arnold, a chemist has the same opinion.
