you will never have a fair competition because all people are born different - people have differing testosterone levels, differing body builds, differing muscles mass, etc. most competitive sports are plagued with doping because hard work only takes you so far before your body hits its limit.
just let the olympics and shit be a showcase and celebration of what humans can accomplish, fuck it make doping legal as well, i wanna see how wild humans can get
Still not great, it's really easy to use to exploit people, and it would basically become mandatory to dope in order to succeed in competitive sports and not get annihilated by the 2.5 meter tall, 200 kilograms of pure muscle 19 year old about to tackle your ass.
