Not sure why anyone would be shocked at top boxers taking performance enhancing drugs. It's happening in every sport...and if you don't think it is...you are delusional. And forget steroids, HGH, and all that stuff. There is a whole new slew of drugs that cannot even be detected through urine and blood tests...it would take a muscle biopsy to show it is in an athlete's system (you can find plenty of articles about this from reputable, scientific sources on the net). This is just a reality of modern sports. Not pointing at any particular fighter...but just saying people are naive if they don't think it's happening.
