hey guys, I am a college athlete and workout 4-5 days a week. I have been taking Cell Tech and protien the past couple years and have had great results. But i have noticed that when I get off cell tech i lose a little muscle definition do to the loss of water absorbtion in my muscles do to cell tech. I have been recently looking at supplements and have read about NO2 in all my muscle magazines and read that it gives you a perpetual pump and brings in blood to the muscle cells instead of water into the cells. I have asked around and other athletes at my college and not alot know much about it, was just wondering if any of you have taken it or know anything about it and if you have taken it or know anything about it do you recommend it? I have also heard that it may help increase your penis size do to the whole blood thing!!!!! But any input would be appreciated!!
