Its my personal belief,that mo is either using epo,blood doping or combinations of drugs.Obviously theres no proof,and im no expert,thats just my opinion.Its strange that he went from not having a kick,to suddenly having one of the most devestating kicks in the history of the sport.Also strange that he suddenly improved,to go with that kick.Still,even without drugs he'd still be a super gifted athlete,probably able to do a 3.37 1500,13.10 5000,and sub 28 10'000 metres.
