Painkillers are a banned substance, but they are banned to protect the athlete using them because there is a serious risk of the athlete competing well above their threshold and causing serious injury to themselves. The biggest risk for a guy getting a hand injection is that if he suffers a hand injury, he'll be blissfully unaware and continue to punch hard with it, worsening the injury. And Floyd only fights in Nevada where it's legal, so he isn't breaking the rules.

So if you want to attack LEGAL "performance enhancers", why not shit on a guy for drinking protein shakes? Or taking vitamin supplements? Those are performance enhancers too.

I had to laugh at the Pac Tards all these years saying "how can Mayweather talk about Pac using steroids when he uses hand injections", like those two things are in the same fucking discussion...
