."My brother Ken did them his whole life," Frank told ***********. "Why do you think that his mind is so fried? Why do you think he crumbles before the big fights? He's got no psyche. He let steroids give him a false sense of security and the moment that stuff is gone he's no longer superman. He's just a regular man. But without all the hard work and without all the belief in himself that a regular man would have if he got up to that point. He's the only guy that I'll tell on, because he's always in trouble anyway.
fighters such as Dan Severn have long hinted that Ken uses steroids, and there's widespread speculation that Ken used during his days with the WWE.LINK
All i can say is that i'm not surprised one bit that Ken does steriods.
