gh - growth hormone (somatropin) - therapy for height is in GH deficient CHILDREN, once the epiphyseal plates (that is the end of your long bones) have fused, they do not grow in length, although they may thicken with GH.
GH will also have all of your internal organs grow in size if you take too much for too long.
I have been reading loads of scientific papers on GH, personally, I am starting to think it is over-rated, too many sides for what it might provide:
1. Fat mobilisation from the abdomen to peripheral regions
2. Some lean tissue growth (including internal organs).
When you see some people with GH bellies and funny faces, well, YUCK.
