In May 2016 the National Doping Control Commission of Chile (CNCD) has reported an anti-doping rule violation against the Athlete Juan Guillermo Medina Muñoz after his A and B samples tested positive for the prohibited substances Mesterolone, Methyltestosterone and Stanozolol.
After notification a provisional suspension was ordered. The Athlete filed a statement in his defence and he was heard for the Disciplinary Panel of the Tribunal de Expertos en Dopaje (TED).
The Athlete denied the intentional use of the substances and explained with medical evidence that he had used prescribed medications as treatment for his low testosterone levels.
The Panel finds that the presence of the prohibited substances has been established in the Athlete's samples and accordingly that he committed an anti-doping rule violation.
The Panel established that the medications Proviron (Mesterolone) and Nolvadex (Tamoxifen) were prescribed for the Athlete's treatment. However the Panel holds that Tamoxifen is unavailable in Chile and the presence of this substance was not detected in his samples. The Athlete's application for a TUE was denied.
Further the Panel considers that the prescribed medications could not explain the presence of the prohibited substances Stanozolol and Methyltestosterone in his samples.
Therefore the TED Disciplinary Panel decides on 6 October 2016 to impose a 4 year period of ineligibility on the Athlete, starting on the date of the provisional suspension, i.e. on 6 May 2016.
