Bro, he does not take any steroids, he has one of the best nutritionists out there.
Eating healthy and training the right way can give you a great body physique and when you have the genes, which he obviously has, you look more lean.
Of course he takes a lot of food additives, like protein, creatine, boosters and many more this are the most common that most people know.
It was a nice fight AJ won clearly, props to Pulev for taking this masive BOMBS in 3rd round. And then after that!
AJ vs Fury next!
And just for the comments above, AJ wanted to fight both Wilder and Fury but both of them turned down, Fury admitted, Wilder wanted a higher pay-check!
I'm not saying it because im a fan, it's out there!
