Khan scared of Maidana?

[The Congressman]

Khan shouldnt be scared of anyone now he has Roach injecting him with this juice.

Watch another chinny fighter whos been knocked out early by a nobody suddenly develop fantastic punch resistance as he moves up in weights under Roach's guidance.

Can you please explain to me how steroids can improve your punch resistance?

It gives you better powers of recovery

...after being counted out.
