Colombia “surprised” at positive doping control from Costa Rica
Marlon Perez said that he was “surprised” at his positive doping controls from the Vuelta a Costa Rica, denying that he had ever used performance-enhancing drugs. The UCI announced last week that he had tested positive at the race last December.
He returned analytical findings of metabolite GW1516 sulfone – Metabolic Modulator and sibutramine in urine samples collected from him during tests at the Vuelta a Costa Rica on 19 and 26 December, 2012, after winning the stages on those days.
In a statement released on Friday, he said “I am very surprised by this, because in no time have I taken any medications to improve my athletic performance.”
The 37-year-old, who did not find a team for the 2013 season, mentioned the possibility that he may have used a tainted product. “During the months of August and September, because I was a little overweight, consumed a natural product to help decrease my size, but not to improve my athletic performance.”
Perez reiterated that he did not dope for the race and that his team was also innocent. “I wish to make clear that my participation in the Tour of Costa Rica 2012, did not consume any medication thinking of improving my athletic performance and GW-Shimano team had nothing to do with my preparation for this event.”
The Colombian turned pro in 2003 with 05 Orbitel, riding later with Colombia-Selle Italia, Tenax and Universal Cafe before hitting the top league with Caisse d'Epargne in 2008 and 2009. From there he went to the amateur team GW-Shimano
