I repeat, all athletes use different doping to improve the results of its features. Only a few manage to deceive the monitoring organizations, while other competitors are not able to deceive the control and they are forbidden to speak at the event. At this time, the Russian athletes are out of luck.

Meldoniy (Meldonium) scandal

The Meldonium scandal began developing earlier this year after late last year WADA suddenly declared Meldonium to be a super-doping agent and banned it. It quickly turned out that Meldonium stayed in one’s bloodstream for months, and so, even those athletes who ended Meldonium usage immediately after the ban, tested positive months later and were promptly banned from all international competitions. WADA faced criticism for its ‘poorly researched and tested’ decision on Meldonium, but it simply shrugged off any such criticism and kept plowing on.

The most famous athlete they got on Meldonium scandal was tennis star Maria Sharapova, who, as a result, is under a 2-year playing ban, and of course, she is missing the Rio Olympics. Why it was important to get Sharapova? Along with Yelena Isinbayeva, she is the face of the Russian sport. She was the Russian flag bearer at the London Olympics, and just like Isinbayeva, she is universally loved and admired.
