That is amazing strength at such a young age. I also heard him say he did 315lb barbell curls. What do you guys think? 
possible and done by freaks and priest is a freak when it comes to bodybuilding,,ofcourse you got to be hormonized for any lift of that kind with specific compounds that will let you do it with out injuring yourself
8 years ago i used to train with a russian fella that was 6 feet 220lb with minimal use of hormones as in basics dianabol and sustas,,but he was a freak of nature,,he was standing 10% 220 6feet,,very solid and exellent muscle shape and strength,,this fella curled 265lb for 6-8 reps with strict form on minimal hormones who doesnt give as much strength as halo anapolon and the such,,why? because he was a freak,,he never had no abs but he sure had the shape of a bodybuilder same as boyer
now take this freak and change him with priest which is most likley the freakiest white bodybuilder to walk earth and what you get is 315 curls done not on a regular basis but defenitely done once in a while
priest is a very strong lifter,,the fact he doesnt lift enourmous amount of weights all the time especially over 30,, is what give him his long life in the sport because you got to be smart not only strong when it comes to your career,,you can develop exellent physiqe with combination of heavy and not so heavy training,,heavy training by itself will only lead to injury at the end,,thats why the smart bodybuilder know when to go heavy and when to lay back depending on many factors such as age drugs used lifting technics bodyfat% etc
