Vitali Bernatski told the Eesti Päevaleht daily today that he supplied well-known athletes with the banned substance EPO between 1995 to 2007, prompting authorities to act.
The Estonian Olympic Committee and the Anti-Doping Agency are set to meet to discuss the next steps, with the head of EOC, Neinar Seli, saying that an investigative commission is likely to be set up.
Kärt Anvelt, the journalist responsible for the article, told ETV this morning that the paper has sources other than Bernatski who confirm that such activities took place in Tartu in the 1990s and 2000s.
Olympic gold medalist and MP Erki Nool said that, during the period mentioned, Estonia had very few to athletes competing in endurance fields, adding that EPO does not help long jumpers or throwers.
The drug improves the overall oxygen delivery system, allowing more oxygen to travel to muscles, improving endurance capacity.
