How long for Letrozole to start working??
Ive read that some here have used Letrozole to lower E2 for those that can't effectively lower with Adex.
Ive read it takes up to 60 days to reach steady blood levels and I can see because of the long half life (4days).
Question is how long does it take Letrozole to start working? Do I have to take another Aromatase inhibitor (AI) like arimidex until Letro kicks in??
Just got labs back and at .5mg Adex daily my E2 sensitive test was 64 pg/ml with SHGB at only 12 nmol/L.
