Mirko “Cro Cop” Filipović admits using grow hormone to heal injured shoulder faster. Cro Cop says on his own website that he didn´t retire because of the the failed drug test he knew will come and be public. He claims the reason was because of injuries. It is very sad that a well known and legendary fighter like Mirko “Cro Cop” Filipović turned to a illegal and banned performance enhancing drug.
First day retired and I already have my first problems.
