Not all top BB use direct oil inject to inflate thier muscles and egos. Frankly some are bb's are afraid of it or can not find somebody to actually do it for them. There are some, like Milos in the past and as recent as just a couple of years ago with busted legs and all with out pause were direct oil injecting. But Milos is not alone- markus, kamali, ronnie, nasser and others were not afraid either.
-keep it real-
