His most recent show, he lost, and went online with a whole video diatribe complaining about how he should have won. Now, whether the guy who beat Bostin was a more complete package (shorter BBer, probably better symmetry IMO based on the few pics I saw), or the IFBB didn't want to reward an ass clown to is making his following by publicly "exposing" just how much reliance on various PEDs there is in the sport.. well, you can make your own guess.
I've known plenty of National level competitors as well as IFBB Pros over the years, and to this day, have several I count as very good friends. Not everyone wants to hear this, BUT, what I've found is that more often than not, the better competitors are on a hell of a lot less than the wanna be's.
The general consensus I read from the industry is one of negativity towards this particular gentleman.
