Well kind sir, Speaking on my behalf I would like to say yes we do. and speaking on behalf of most of the ppl I know on this site, its not just hobbie/past time etc. Its a way of life. God reached down and plucked a few of us and gave us the discipline to become the physical elite. These powders and other supps help us not just physically but mentally... Even tho half the supps we use dont work or are not worth shet they still give us something to spend our money on, test on our bodies, and flat out talk about. I personally have wasted lots on supplements that did nothing for me and im only 20 so i can imagine what others here have spent. Not sure if i hit the primary question on the head or even nibbled around the edges but I assure you I need these supps. PLus if your going to do something whether it be a hobbie/training/small comp... DO it to the fuLLesT! Do everything you can to be the best, besides. You'll be happier that you did!!
P.S. OOhhh Rah!
