tbf probably everyone in the past was on something majority of stuff on the banned list wasn't even banned back in the day im sure what povetkin was caught taken had only been added to the list just before he got popped?
Seeing this guy who campaigned at LHW and at Cruiser look like he had a ****ing mountain across his back was crazy.
Anyone who was actually caught was super juicing: Mayweather with the masking IV, Holyfield "Evan Fields", Mosely, Jones Jr, Botha, Briggs, Povetkin, Klitschko, Fury, Toney...so many to mention them all. Then there is the eyeball test. People that are just lean and jacked all year round. People who are already muscular adding even more muscle in a few months/a year. Nowadays with people fighting once a year, it's super easy to be training on gear most the year then time your fights to pass the testing.
There are currently more ”roids” than there are tests to find them,hence why they keep the samples so long now to further test them when new testing procedures become available. Best thing to do if you going to cheat is to do the Mayweather,have the testing agency in your back pocket and get them to grant you a TUE 18 days after you have fought . https://www.sbnation.com/longform/2015/9/9/9271811/can-boxing-trust-usada
