look at the eyes of ANY top US sprinter in the minutes before a race and you will clearly see they are on something.
I have no idea how US athletes continue to get away with it.
Apparently they just stay a step ahead of what’s being banned.
If it were up to me i’d take blood, nail and hair samples from every top 5 winner and keep them on file for future testing (when whatever they are on and banned at a later date). If such a system was implemented I suspect nearly every record for the past 40 years+ would be overturned.
Many high level and pro athletes will tell you that at the highest levels of all athletic competition the use of PEDs is around 90%.
They get away with it because governing bodies want them to, or are at least ambivalent. Who thinks a mediocre pitcher like Jake Arrieta isn’t doping?
Yes, masking strategies are very good, and natural substances can be carefully absorbed into the ‘high normal’ range. But political correctness influences doping like everything else (thus the Williams sisters).
Most of the big-time governing bodies keep samples for up to 8-10 years.
There was an article recently about them retesting samples from a previous Olympics (2008?). There were some new positives, but I don’t remember if any were American.
