No.... but if your a small man fighting way outside of your weight yes you probably need steroids, not advocating it its horrible for all sports but... it doesnt change the fact mosley is a gret fighter, as far as those guys on the list roy jones most likley was on the juice as you say, roids sad to say makes ordinary athlete very good, a good one great and a great one like jones almost super human...... (in terms of physical abilities recovery etc...) why do you think there are som m,any 40 plus athletes today, yes people are healthier but um could it be steoids??
