Just asking basically because Human Growth Hormone was genetically engineered for pituitary dwarfs to help with the growth of long bones during later childhood/puberty. It was not easy to manufacture but now it is easier.
If someone has found the Horse Growth Hormone gene and has produced the stuff... that would be interesting to know.
It probably is not a lot diff. from Human Growth hormone. But the cyclist to put that into his body... thats is just flat out dumb. He could have had a very bad reaction to it if it really is produced for or in a horse.

Anyways I read fischer and he cleared it up. The chemical in question supposedly helps with the release of Horse growth Hormone. That site looks bogus to me. Probably sell you saline labeled super horse serum.
