The professionals use HGH, Peptides and gear in amazingly large amounts. I don't see them as retardly enlarged. I have been using 5ius per day of GH for a very long time as well as peptides here and there and I don't have some crazy looking abdominal region. Anything you do that is way over the normal or acceptable amount is going to have negative consequences. Remember plain and simple these are drugs and you are messing with your hormone levels. Don't be stupid and you will be fine.
