I always hear people talk about how HGH somehow makes organs larger and how it causes extended bellies. Extended bellies have nothing to do with taking GH, and has everything to do with poor diets, becoming too large in the off season and an organ called the omentum.

If you pick up a medical A&P text that is detailed and updated, you will find an organ known as the greater and lesser omentum, (I won't go through all the technical mumbo) that is located under the abdominal wall, and attaches to the stomach, colon and the liver. This organ is primarily composed of fat tissue with a cover of what is called peritoneum.

This organ serves as a sort of filter and deposit for excess fat that is consumed (saturated fat). As such this organ is able to grow larger in relation to fat consumption independently of subcutaneous fat deposit. As this organ grows larger it creates a round belly and pushes against the abdominal muscle creating a hard or extended belly (EB).

Does anyone have that uncle who eats fried foods and drinks beer all day with the 10in biceps 15 inch legs and a belly you could ski down? This is an example of an enlarged omentum, and my bet is uncle jimmy lou isn't in the bathroom at the BBQ's downing HGH.

If you look on any BB stage you will no doubt see many guys who when relaxed still have a six pack, but an extended round belly. Typically most BB's will only diet down for a period of 12 weeks, allowing enough time to adequately shed subcutaneous BF, but not sufficient time to shrink back down the omentum (which can be done by the way).

For example after the new IFBB regulations of EB, Ronnie Coleman came in that year with a flatter stomach. On top of better abdominal control, he stayed in a contest diet mode all year round and ate less over all food (including saturated fat).
