Most of the re-analysis of samples from both Beijing (2008) and London has resulted in positive findings of Dehydrochlormethyltestosterone. In 2013 a new testing methodologies was developed for the substance and for Stanozolol. This has caused a raise in cases involving Dehydrochlormethyltestosterone.

Press release from IOC
The protection of clean athletes and the fight against doping are top priorities for the International Olympic Committee (IOC), as outlined in Olympic Agenda 2020, the IOC’s strategic roadmap for the future of the Olympic Movement. The IOC is currently conducting additional analyses on the samples collected from the Olympic Games London 2012. This programme, which uses the latest scientific analysis methods, aims to test samples for all substances prohibited in 2012.

The IOC has delegated the selection of samples to be reanalysed and the results management to the International Testing Agency (ITA) and the ITA thus brought forward these cases.

The notification sent by the ITA to the athletes concerned when initiating proceedings gives them the choice to have their case heard before the CAS or before an IOC Disciplinary Commission. This choice is given as the Anti-Doping Rules (ADR) for the Olympic Games London 2012 still apply for cases that arise from the current reanalyses.

As part of this process, the IOC today announced that one athlete has been disqualified from the Olympic Games London 2012. The details follow.

Jevgenij SHUKLIN, 33, of Lithuania, competing in the Men’s Canoe Sprint C-1 200m event in which he ranked 2nd and was awarded the silver medal, has been disqualified from the Olympic Games London 2012. Re-analysis of Shuklin’s samples from London 2012 resulted in a positive test for the prohibited substances Dehydrochlormethyltestosterone (oral turinabol).

The IOC Disciplinary Commission, composed for this case of Mr Denis Oswald (Chairman), Mrs Gunilla Lindberg and Mr Juan Antonio Samaranch, decided the following:

I. The Athlete, Jevgenij Shuklin:

ii. is disqualified from the events in which he participated upon the occasion of the 2012 Olympic Games, namely, the Men’s Canoe Sprint C-1 200m event.
