Its highly unlikely given his behaviour, though not impossible, that PBF is using a banned PED. To dominate a sport like he has without the use of these drugs is rather remarkable. As unfair as it is to point fingers at those fighters who may appear suspicious but have never tested positive, its equally unfair that clean fighters have to be judged agaisnt the cheaters without reference to the extra hurdles thay must clear..since one does not want to make false accusations.

so the statrus quo favors the cheaters. therefore, a word should be said about apparently clean athletes whose accomplishments (like say Derek Jeter's and Ken Griffey's) are actually greater than they appear because of the ubiquitous use of PEDs.

Kudos to PBF.
