Belgian magazine Humo has published allegations on its website that Alberto Contador used Clenbuterol after the Criterium du Dauphiné in June. The magazine quoted an anonymous source close to his Astana team, who also alleged that Contador withdrew blood after the event to be used for a transfusion at a later date.
Contador has repeatedly denied knowingly using Clenbuterol and has refuted claims cited in L’Équipe that his positive sample for the substance is explicable by a blood transfusion during the Tour de France. The Spanish rider has since stated that he will not speak to the press on the matter again until after a ruling has been made on his case.
Humo’s unnamed source from the Astana set-up claimed that Contador used Clenbuterol in order to lose weight. The source suggests that it was used in combination with the thyroid hormone Triiodothyronine, which aids in the digestion of fat.
“During the Dauphiné, Contador was still a little overweight,” the source told Humo. “Ordinary people would not notice, but he was still a kilo or two off. That’s what Clenbuterol is used for: to lose the last kilos and at the same time not decrease muscle mass, or in the best case, increase it.”
Contador finished in second place overall at the Dauphiné, winning the queen stage to l’Alpe d’Huez.
The interview will be published in full in the print edition of the magazine on Tuesday.
