Between 2012 to 2015, the Disappearing Positive Methodology was used on 643 positive samples, the investigation found. Russian athletes from the vast majority of summer and winter Olympic sports benefited from the system.
Rodchenkov said he created a three-drug cocktail of illegal steroid substances—metenolone, trenbolone, and oxandrolone—that he mixed with liquor and gave to dozens of Russian competitors.
During the 2012 London Olympics many of Russia’s top athletes were using the cocktails, Rodchenkov said. The cocktails were distributed to various sport federations by Irina Rodionova, the deputy director of the Center of Sports Preparation of National Teams of Russia (CSP).

In addition, the Sochi lab operated a unique sample swapping method to avoid Russian athletes from being caught doping during the Olympics, the investigation found.
The McLaren report says the Russian Ministry of Sport directed, controlled, and oversaw the manipulation of athlete’s analytical results or sample swapping, with the help of the Russian Federal Security Service, CSP, and both Moscow and Sochi labs.
