I think it needs to be debated whether HGH is even a PED. It is used to boost the bodies ability to recover from injury or to counteract effects of aging. I think if you can have something prescribed that will help you recover from injury quicker and doesn't necessarily have any long term side effects, it may not be a "PED".
I think much more clinical testing needs to be done to see if it even is a benefit and if there are adverse effects.
If any of you "blew out your knee" and could have something prescribed that would help you recover. Would it not be better to use that with a rehabilitation regiment, than pain-killers which by masking the pain can actually lead to more damage? Do you not think you would want to have that option, so you could get back to working and living your life?
As Biotechnology/Pharmacology continues to advance I guess this debate will always exist. What's performance enhancing versus medically justified?
