Bodybuilders of 10, 20, 30 years ago had the same amazing physques that we all see today. Physiques that we would kill for. But those BB's of years back didn't have shit like CLA, r-ALA, Creatine, NO2 etc etc etc. You get the picture! Yet! Without all this shit...they still became beasts! Right??? Ok! So therefore...is it really necessary for US to take those supplements that are available to us today? They did back in the past without all these supps! Why do we need them?
