HGH, EPO and the occasional steroid cycle, his head grew just like Barry Bonds. Boxing drug testing is laughable because boxing isn't an association like the NFL or NBA so they don't test you year round and they don't compare your testosterone levels throughout the year. So basically all they do is **** test you within your training camp, not to mention urine does not detect blood doping or HGH. Someone might blow the whistle on him years from now or he might just end up looking like a completely different fighter if he agrees to 0 day cutoff and that will be proof enough.
A simple request if you have nothing to hide and everything you've been doing is legal right? This question will get spunned to death by *******s but at the end of the day they have no real answer for it.
ariza isnt great, hes just famous because he trains a popular fighter, there are other conditioning coaches out there who are just as good or better.
