yeah there's a physical limit in him. base was around 40 tons, SSJ didn't have a problem with that but nonetheless, a physical limit's on him in the first place. there really isn't a whole lot that shows difference from humans - outside the tail, transformations, and more specific design for combat (including a 'get stronger if you get your ass kicked' card) they really weren't any different. so yeah, he's mostly the same as any other organic.
