is it all these fighters now adays are looking for advantages to get more money and guarantee their wins? or is it the doping authority stepping up their rules and adding things that in the past were ok to use, and its not a clear cut census on what u cant use? personally i think u should not use anything but eat food and drink water an gatorade and take regular vitamins to prepare for fights. im not sure why all these people are coming up positive now. it seems weird.
