It will lead to eradication of doping from boxing.
What does Freddie Roach believe about dramatic changes that have occurred in physique and performance of the boxer Juan Manuel Marquez. Actually, there are various points of view about this athlete and dramatic changes in him. A lot of individuals think that he has taken steroids that have caused these changes in him. As for Freddie Roach, he suggests that Angel Guillermo Memo Heredia has supplied Juan Manuel Marquez with anabolic steroids.
Memo Heredia is an admitted distributor of steroids. He acknowledged that he had supplied many top athletes with anabolic steroids.

But he has to do it because this is the nature of boxing.
While Alex Arizo affirms that Memo Heredia doesn’t provide steroids to Marquez, Freddie Roach has own point of view. He continues to believe that Marquez is tainted. According to Freddie Roach, dramatic physical transformations of this athlete display that he administers steroids and/or other doping products.
