My masseter shouldn't reacquire its full size unless I expose my muscles to the same load?

It was under before correct? If I get botox in my masseter and temporalis muscle, I know the effects of botox wear off after 4-6 months. But the botox should paralyze and atrophy my muscles right? It shouldn't reacquire its full size unless I expose my muscles to the same load it was under before correct? So if i stopped clenching and limited jaw movement, I should be fine, correct?
