Mo's progression over the years so you can make your own judgments.
Some comments. He moved to Al Sal in early 2011 when he had already run 12:57, 7:34 and 3:33.Although he had run 10000m before the move to the US he had only ever run it 3 times and had never really had a serious crack at it. It is also interesting to note he ran 1:48.69 for 800m at age 20 when his PB for 1500m was still only 3:43 so he has obviously always had decent speed although it's moved on a whole other level from then. Would be interesting to see what he could run for 800m now! The most 1500m races he ran in a year was 5 in 2005 when he was 22 before starting to take running really seriously and moving to train with the Kenyans in London and having a proper go at the 5000m. In the last 5 years he has only run 1500m 7 times and did not run it at all in 2010 and 2011 otherwise I’m sure there would not be such a big jump in his 1500m progression. The 1500m tonight was also near perfect in terms of conditions and having people out in front to chase to allow him to run so quick.
Personally I think in middle distance and distance running we are in the era of legal performance enhancers with stuff like thyroxin which is allowing high level performances without positive tests and allowing performances close to what was produced by the cheats in the EPO era. I don't think Mo is doping with banned substances but I would not be surprised if he was taking non banned substances which are morally questionable.
