If they agree to it in contracts? We don't care when they're in oxygen chambers for hours, or training in altitude, or doing anything else they can do to simulate. We can't control genetics to reduce people's power if they have natural explosiveness that others lack.
There could be arguments for it, but I am firmly against it. I believe it is unfair to the sport and the fighters who don't use them. Shouldn't boxing be a sport, where you can only succeed though your own hard work, dedication and talent? Its not bodybuilding where the winner is the one who spiked his ass with anabolic steroids the most.
PEDs aren't going to make them a better boxer. Might make them train more efficiently and have more stamina though. That can already be different depending on genetics.
You asked if they should be legal for boxers if it's negotiated into the contract. That's a nonsensical question. Let's clean it up and assume PEDs are legal in general. The question at that point is whether or not they should be legal in boxing. The answer is no.
That's amusing coming from a guy who is asking if PED use should be able to be negotiated into a fight contract.
No. PEDs shouldn't be allowed, ever. There isn't a single PED I'm aware of which doesn't have serious side effects. Boxers aren't going to know, or be told, about these side effects, so it's easier to protect fighters by banning them. Aside from that, things like power can be improved by PEDs. A chin can't, nor can they protect vital organs from protection. You can make fighters dish out unnatural punishment but there's nothing to help them take unnatural punishment.
Again, idiot.... I asked should they be LEGAL. You obviously didn't read the question and are now stuck in this web of stupidity you will never get out of.
Not a better boxer, but they will give them an physical edge. Wouldn't that be unfair? Some fighters that are less physically gifted rely on their speed, stamina and high workmate to beat fighters that are more of the slugger/puncher variety. PED's might erase the only advantages some fighters have over the others. That would be pretty unfair.
******?? Kinda rich coming from a person asking if perfomance enahnchers should be used in boxing. If a runner is on PEDS so what he runs faster then his opponent If a bodybuilder is on PEDS so what he looks better then the competition If a boxer is on PEDS he endangers his opponents life a bit more......................... WHY SHOULD THAT BE LEGAL. WHILE YOUR AT IT WHY DON'T YOU ASK IF PLASTER OF PARIS SHOULD BE ALLOWED IN BOXING??
If they want to, why not? It's their choice, isn't it? You're not answering the question, you're crying about cheating. If both fighters agree to it, what business is it of yours?
