Ask Duncan Spencer about his troubles with a banned substance. He was having a hard time with his back so he took a banned substance to help him with his quality of life. It worked that well that he was able to play cricket again at an elite level.
He gained medical advise as to how long it would take to be out of his system and he waited that time before playing - he then got a call-back in to the WA side and was drug tested and it was still in his system. He received a 2 year ban.
You may call it thinking outside the box but its a bloody stupid idea and should not be entertained by Freo.
First off don't compare a laundry list of "banned substances" with HGH which is incredibly hard to detect as it's natural and released in cycles in the body every day. If you get caught doing any drug you simply are too moronic to take drugs in the first place. The guys who make millions being athletes are certainly, without a doubt, on performance enhancers. Not all performance enhancers are illegal, and many aren't widely known. It would be stupid for athletes to not be on the best gear, whether it's legal or not, the only issue is one of getting caught doing it and with the right knowledge and money not getting caught is pretty much guaranteed. Why is it stupid to not be on them? They make a lot more money being the best than being the worst.
And there are issues with long term HGH use that people like GSP (a little) and body builders (a lot) show. Organ growth, distended bellies, etc. No one says being one of the best athletes on the planet comes at ZERO RISK. However to fix his knee I would recommend Mora does HGH to help get him over his current hurdles. He isn't playing so what's the harm? It's currently against the rules for him to do it as an AFL player though even though you can get a prescription for it here, same as with testosterone, and that is stupidity.
