Stunting Height

A question here out of pure curiosity: I know that steroids stunt growth by prematurely closing your growth plates because of excess estrogen, correct? At least in layman’s (read: me) terms. If sufficient doses of an estrogen BLOCKER such as Arimidex were used during a cycle, could this risk be eliminated or lessened? I have talked to many people who have grown vertically after a couple cycles. Just wondering if this might be the reason.
