Really funny that people think you have to go to RIZIN to inject PEDS<45>
It is no problem at all to do it within the UFC and stars like Jones or Romero and countless others
continue to cheat in every possible way. PED testing continues to be more of an intelligence test.
You have to have a good PED experienced team in the background with I would say at least one shady doctor and on you go. Microdosing, HGH, EPO.
Give UFC athletes a biopassport and testing like in cycling at the TDF and you catch many in the rooster again. Its a question of how much money an athlete is willing to invest into shielding himself from positive tests.
Only difference to japan is that there you need less effort to mask it.
