Speaking to your question about "what the long term effects of these drugs are":
My wife put together a together a pretty interesting video about the "faustian bargain" which is IGF-1 (used as a proxy measure for growth hormone)... video is replete with examples of the effects of low IGF-1/GH or high IGF-1/GH both in animal models and humans.
One of the more interesting points in the video is the fact that people with polymorphisms that make their IGF-1 receptor experience some slight loss of function actually live longer (in general).

The video also links to an article which has a bibliography if you're interested.
- thesz 12y agoI viewed the video to a half and found enough difference with what I know that I cannot agree with her conclusions. It is more complicated than performance/longevity. Especially when we going to humans from animals. For example, reaction speed correlates with longevity: http://www.ncbi.nlm.nih.gov/pubmed/16079205 http://www.ncbi.nlm.nih.gov/pubmed/16079205 Reaction speed needs muscle power and neural signal power, both are supported by IGF-1. Arm grip in midlife is stronger for centenarians: http://www.ncbi.nlm.nih.gov/pubmed/21541735 http://www.ncbi.nlm.nih.gov/pubmed/21541735 Thus, while entertaining, the video of your wife is too quick to jump to conclusions.
