I know people say hgh cause the guts etc but in my opinion and from what ive read its igf1. Hgh makes bone and muscle grow. Igf1 makes everything grow including tendons cartilage etc. I know hgh increases igf levels so it is indirectly responsible but it is actually igf that makes everything grow not hgh. Or have i just written alot of bro science lol?
The abdominal wall can and does get stretched out as well. Phil has separated abs if look at the pics. Enormous amounts of food and heavy lifting does contribute, it's not just an excuse trying to hide the real cause (drugs). I don't think the organs have hypertrophied to such an extent they tear up the abs and sometimes cause hernias like in some bb'ers.
Not saying drugs aren't a factor though.
The problem is basically trying to force the scale to go up too much.
