Thanks you for your very informative and insightful comment. From what I understand, the entire doping scandal is based upon the testimony of that one individual. It is shameful that so many would be denied the right to fairly compete because of that one person who the west has decided to make a hero of. It is noteworthy also that Meldonium was not categorized as a banned substance by WADA until 2016 in the run up to the summer Olympics and was used as an excuse to ban the Russian team. https://en.wikipedia.org/wiki/Meldonium
