Just thought I would put my two cents in, since I have been using creatine since I was 15... 8 long years ago. I started out taking the good old creatine monohydrate, which you had to drink a juice with to get it to stick to the muscles and absorb properly. But technology has changed, and so has creatine, and I have yet to find one person who has used CELLTECH and not gotten great gains with it, both strength and speed. And Im not quoting anyone here or anything, Im just stating facts from years and years of basically living in a gym, and watching my father train, who was the first American to weigh under 250 pounds to bench 500 pounds at 50 years old. I preach 3 things.. creatine, protein, and ephreda. However, my dad has been messing around with NO2, and Ive known some other guys who have expericanced great gains with it. And after I get use to living off no sleep because of my little girl.. I think Im going to experiment with it, and I will make sure to keep people in here informed with the results.
