if you have unlimited money and can just eat, train, eat sleep repeat you can get there a lot quicker than someone who can't do all those things. it would also depend on what you kind of base your starting with. if you have been training for a few years compared to the guy who never lifted obv you can reach that level quicker.
either way you need to be able to spend a good amount of money on gear each month to get there.
