It was a show on people who grow rapidly because of a brain tumor that presses on there brain and makes there body produce massive amounts of human growth hormone.
In ever instance they showed. After the tumor was taken out, and the human groth hormone levels droped back to normal. Doctors said the "giants" would live a full normaly life (except there over 7 foot tall).
Seems that using it in 12 week cycles could be pretty safe as far as life threating side effects then no?
BTW only one of the giants had a large nose. I wonder what causes the large nose/forhead/ lower jaw crap. Look at robert waldo, he was like 8' 6" tall, but he looked normal other than that. HGH was racing though his body from puberty untill the day he died in his 40's.
