Abuse of PED's in sports has created a stigma around all those substances to the point where even legitimate, medical use and research is being looked down upon. With that said there IS some doctors in Canada that acknowledge that there are benefits to some of that stuff for healing/therapy purposes and will recommend or even prescribe test, GH, etc. for certain injuries but this is all very much under the table/underground and you have to "know the right people".......or that's what I hear anyways.
You bet your *** that if some top athlete gets injured and the question becomes "is he going to take the moral high ground and sit out the next 10 games" or "take some X, Y and Z and be back on the field in 3 games", the choice is usually pretty simple. Especially when missing those extra games will cost a few hundred thousand dollars and some disappointed fans.
