I am saying the opposite? Well, first of all you have to look at the time frames in which you measure the performance. Dopers die early, and there we leave that part.
Most doping works based on lowering body sensivity and increasing aggression in a world in which many believe they are better when they scare of the others.
This means that a sprinter, and Ben Johnson is Hollywood fake on next level, that uses steroids will be extremly aggressive and not feel any feedback from his body comperable to a life and death fighting scenario in which you lick your wounds after the adrenalin gets build down by the body and the enemy is either dead or you just got away even so injured.
Obviously, such situations are extrem and also extremly rare in a lifetime. They are also extremely stressful for the body, beside the human mind.
Doping creates that every day and some even top that on competition day.
Instead, training naturaly based on body sensitive feedback with also long times of rest on top of recovery based on muscle pain and mind set will create way better results and create a longer life. For everything, we need to train body and mind. In the same way that a school kid needs to learn to sit 8h on a chair, the educated youngster starting an apprenticeship has to learn again to stand and walk for 8h.
In sports that also means to understand how to move as a sprinter, how to move on a bycicle or how to move swiming or how to dribble a football along with tactics and strategies of the game or discipline to becomer better.
No one can think straight on a doping cocktail, but there is an entire society that will help to only have dopers compete.....willing to take every shortcut and cheat against a better.
So, doping is a lie of those that never won.
