LOL. I'm so glad you're not in charge of important things in this world. There's a reason PEDs are banned. They doing horrible things to fighters bodies long-term. If you allow PEDs, then basically every fighter needs to take them to compete, and thus must incur significant negative effects later in life.
You're either incredibly naive and uninformed, or you're a selfish sociopath. Fighters already have enough risk with CTE later in life. We should at least strive for a PED free sport, so they don't suffer from steroid use later on as well.
