If you just begna traing 6 weeks ago you've got a good couple of years to go before you should even think about such supplementation. The only things that should be used by you at this point are the basics, like creatine, maybe some arginine if you like pumps, etc. Hitting GH or other hormone supplementation right now is most likely a recipe for dissappointment and possible injury, especially since you're no spring chicken. You ain't over the hill, but you can see the top. Caution is the word of the day, and educated choices preferred action.
