He's hitting harder because he's naturally got bigger and filled out. His body,...etc...stamina is all achievable without PED's.
Has he ever had a bad substance in his system after a fight? Or is it just Inklings of random testing containing small levels of clenbuterol?
Just small levels of clenbuterol. Clen if used for ''performance enhancing'' is actually really poor. You'd have to take tons of the stuff and you'd see more of it in Canelo's system in random testing. Canelo would most likely hospitalize himself if he was relying on Clenbuterol as a performance enhancer. Clenbuterol is just a rubbish fat burner and is mostly used to treat asthma and COPD patients. I think it's too risky to take for health complications. His progression as a fighter since his debut has been normal. He's got stronger, hits harder (improved s&c training), and has naturally filled out more. His stamina has improved but it's also because he's better at reserving energy in fights now. It's the same thing with Manny Pacquiao. Pacquiao is naturally gifted and got stronger through normal means of training and better lifestyle choices (eating healthier,..etc...)
