How would taking HGH effect me for being 21 yrs of age?

I know My body is producing large amounts of HGH already but plz let me explain my side first.

I've had an elbow injury for 3 years. I am a college pitcher , highly ranked great possibility of going pro. Now for the past 3 years I have not been able to come back due to my elbow injury. MRI nothing, Bone scan ok, Nerve scan fine and dandy. Therapy doesnt help, Steroids Don't help but allow me to train and make strength gains faster. Now for the past years I've been training more like a bber than a pitcher because of my injury I can't throw above 60% without hurting my arm, making it impossible to throw.

So will takeing 2iu-6iu's help my nagging elbow get back to 100% so I can get on with my life again?

Just for healing not for anything else. Maybe recovery for workouts but thats it.
