nono, youre at a stage where naturaly nothing nomore will happen as far size goes.
if you gonna stay natural, fine, concentrate on getting lean, natty doesnt hold anyone back from doing that, but do train the rest too, or it will wither away, then metaboism slows down etc.no good.
or alternatively, go on gear and train pretty much however you like and have results.
hell even i say natural cant train and eat the same exact way like gearhead, its not possible.
