I understand that bone density may be stimulated while on pharma grad HGH, and some users tend to get bigger heads, wider jaws ect... Some to the point were it looks unpleasant.

So just a question out of curiosity. Is there anything to combat the negative sides of bone growth with GH?
I notice Pros like Phil Heath and others that I know for a fact are on crazy GH regimens but show very little signs they are on it, aside from the freakish muscle gains. Or is it just luck of the genetics?

I'm about to start my first Sero fun and want to avoid the freakish forehead a jawline I've seen in some users.
