in my experience no, that type of hardness and fullness in a very lean state can only happen in a highly androgenic state, lean fall and vascular is not a natural state, lean and flat yes but not androgenically full looking, looks like a natural guy using something like old fashioned anadrol or test suspension in a no carb low sodium environment, what ever he's using its fast acting and he's using armidex or something similar to stop any aromatisation. Just an opinion.
