The ABP started in 2009, which makes the 2012 Olympic champions more likely. I doubt Ohuruogu was doing EPO. The ABP does not detect anabolic steroids.
If Seppelt does not release the name then it is probably a nonsense story from a Russian Doper-Cheater-Liar.
If the Russians have this name of a British Olympic champion...they should have already released it! There is no reason to delay things after the Olympics.
This could be just another stupid Russian Doper-Cheater-Liarâ„¢ lie that was being used as a bluff.
Darn.
