no
he simply dont work them as much as arms,,its a known phenomena,,also his arms are lookin damn too good for the rest of his body,,so either its photo shopped some or he simply got good genetic for arms that thicken to this level and size,,since this is straight out 18 inch,,partly by the use of hormones wehter it is m1t or anadrol its all same thing,,
simply too oily too thick for narural,,in addition his uppoer torso and neck fit more a 160lb guy,,which should give him a warning light to stop working his arms and start workin the rest of his upper torse,,
its like lookin at 160lb guy that has 18 inch cut arms,,each and every one of those guys with 18 inch sculpted arms that weight less than 200lb are hormonized to some degree no matter how good their genetic make up is
