Canelo got caught cheating while putting on muscle to move up and fight GGG, vids were made before that showing how much bulk he had put on to get up to middle due to his short height, Floyd never came down in weight to fight anyone so why would he use PED`s to cut weight? google this to find out if your theory is true because I thought PED`s were only used to put muscle on which is why WWE wrestlers use them and body builders like former Mr Universe Arnie Schwartzenegger.
Clenbuterol has been found to increase short-term work rate and cardiovascular output, and consequently, its anabolic effects in horses can be attributed to exercise output and increased caloric intake. Given its ability to increase basal metabolic rate, maximum heart rate, and exercise output, Clenbuterol has ergogenic properties more closely related to ephedrine or amphetamine.
Too big yes, powerful yes.But still Pac will have more chances against him if it will be fair and not fixed like some of Canelo's last fights.
