TJD-AD 2021-028 Appeal Decision - Boxing
December 16, 2021

In February 2021 the Brazilian Doping Control Authority (ABCD) reported an anti-doping rule violation against the boxer after his sample tested positive for the prohibited substance Enobosarm (Ostarine) in a low concentration. After notification a provisional suspension was ordered and the Athlete filed a statement in his defence.

The Athlete denied the intentional use of the substance and asserted that a contaminated supplement was the source of the prohibited substance. He provided ABCD two opened vials with supplements compounded in a pharmacy. Analysis of these supplements revealed the presence of Ostarine in one of these supplements.

The Compounding pharmacy in questioned confirmed to ABCD that prior on the same day Ostarine was compounded for another person and consequently thereupon the compounding supplement of the Athlete got contaminated.

The Rapporteur finds that the presence of a prohibited substance has been established in the Athlete's sample and accordingly that he committed an anti-doping rule violation.

The Rapporteur concludes that the violation was not intentional and the result of a contaminated supplement. Considered was that he was a high level athlete, had received anti-doping education, and was tested before without issues.

Further the Rapporteur deems that the Athlete acted with some degree of fault or negligence because he used his own unprescribed compounding supplements, not the prescribed supplements of his sports federation, whereas he failed to mention his supplements on the Doping Control Form.

Therefore the TJD-AD decides on 14 September 2021 to impose a 9 month period of ineligibility on the Athlete, starting on the date of the sample collection, i.e on 22 January 2021.
