In July 2017 the National Doping Control Commission of Chile (CNCD) has reported an anti-doping rule violation against the weightlifter Raúl Arturo Ladrón de Guevara after his sample tested positive for the prohibited substances 19-norandrosterone, 19-noretiocholanolone (Nandrolone), Stanozolol and Tamoxifen.
After notification a provisional suspension was ordered. The Athlete failed to file a statement in his defece nor did he appear for the Disciplinary Panel of the Tribunal de Expertos en Dopaje (TED).
Without the Athlete's response and considering the test results the Panel concludes that the Athlete committed the anti-doping rule violation.
Therefore on 15 December 2017 the TED Disciplinary Panel decides to impose a 4 year period of ineligibility on the Athlete starting on the date of the provisional suspension, i.e. 17 July 2017.
