At the moment I'm 24...so GH is on the horizon. As for IGF-1 and Slin, both are on the banned substance list, but how the hell could they test for those if they can't test for GH. As for a test on GH...I wouldn't be suprised if they have one by the next olympics, and I also wouldn't be suprised to see an undetectable version of GH soon thereafter. Chicken and the Egg yet again.
