recently ive been reading about letrozole as a stand alone to work extremely well in raising natural test by almost 100% and LH levels by 339%.. i found this very interesting.. but it does cause estrogen to go to extremely low levels as the dose gets higher(almost non existence in some cases) which can cause many problems.. i was wondering if anyone has had using letrozole with sucess without the use of steroids and using it as a post cycle therapy.. i am curious how it would do as a stand alone and the muscle increases it has..
