going on what i think people generally would do - he used steroids. Don't see why he should be given the benefit of the doubt, ripped or non-ripped!
Would they?
My view is, he may or may not have used steroids, however, I also think there's no reason for him to have needed steriods to get that body. If he used them then he wasted his time because he hasn't acheived anything special, that body looks like the product of a few months of big eating and heavy lifting.
