In July 2017 the National Doping Control Commission of Chile (CNCD) has reported two anti-doping rule violation against the Athlete Roberto Andrés Tello Bolvaran after his samples, collected in April and in May 2017, tested positive for the prohibited substance Testosterone and its metabolites.
After notification a provisional suspension was ordered. The Athlete filed a statement in his defence, supported by evidence and expert witnesses and attended the hearing of the Disciplinary Panel of the Tribunal de Expertos en Dopaje (TED).
At first the Athlete could not explain the test result while anaylisis of his supplements revealed no prohibited substances. Thereupon he established that the skin cream used by his kinesiologist contained Testosterone. The kinesiologist testified and confirmed the use of the cream and that the Athlete was unaware it contained a prohibited substance.
The Panel accepts the evidence and the explanations of the Athlete and witnesses and concludes that the Athlete acted without fault or negligence. Therefore the TED Disciplinary Panel decides on 10 October 2017 to acquit the Athlete.
