The issue is that we've been fed this bullcrap line growing up "Anything is possible" or "You could do anything you put your mind to." The fact of the matter is that it's just not true. Every person has biological and environmental limitations. We are all limited in some way, shape or form. As such, even the human body has its genetic limitations and needs assistance to accomplish remarkable feats of strength, endurance, agility, etc.
Put it this way to people.
Ben Johnson's fastest time clean was around 10.5 sec. At the 1984 Olympics after juicing 3 years he ran 10.22 to take Bronze. 4 years later to win he ran 9.79. That's juicing for 7 years.
So people who believe Bolt is natural think he is running 9.58 natural when Johnson was running 10.5? So what's Bolt supposed to run juiced then fucking 8.9?
We all know about natural limits. Lifting weights, in reality if you do everything right after 3 years you aren't gaining much in that 4th year if anything and from then on that's it. There's no magic protein, no magic supplement you either juice or that's it. These guys with running it's a little different because they've been running since they were kids so growing up they are going to improve as they grow where as lifting weights we all usually start at least around 16 so during or past maturity. But they are going to hit limits around 19 years old and everyone is fed they can keep improving and improving if they just keep working hard. Also because they are genetically gifted and winning everything as kids the common line is 'He was winning everything as a kid he's not juicing it's genetic talent' which is true but only to a point.
Bolt is smart he's coming off juicing a few weeks out from games because it's not needed (actually hurts staying on according to Charlie Francis, Johnson's coach) and Jamaica is helping him avoid tests when he needs to juice. You can see he's clean a LOT offseason. Maybe he has been caught out with an internal test and they helped him out. Who knows.
