Abstract
The article describes gradual disclosure of a state-sponsored doping program operated for four years across the "vast majority" of summer and winter Olympic sports in Russia. According to the two Mclaren commissions reports, about one thousand of Russian athletes, antidoping agency RUSADA and anti-doping laboratories in Moscow and in Sochi during Winter Olympic Games 2014 were involved in the systém.
Such extent of this state-sponsored doping program was never before documented.
