I wouldnt be suprised if Tito ortiz were/is useing HGH since his head is really big though havent been able too find any pictures of him before his HGH use. Has he even confirmed useing that? Looking at Tito Iam not 100% convinced his been useing HGH except looking at his face, he got a huge mandible. Though his hands are fairly small and so are his feet. Face feet and hands are usally affected by HGH use. Have a look at Jay Cutler whom Iam rather sure has been useing HGH. He got that same big jaw as Tito but his hands are really big and so are his feet. So I come too think Tito is as said born that way.
