Letrozole Application


For pre-contest bodybuilders, Letrozole is almost a necessity to eliminate water retention and achieve the ripped look necessary to compete in today’s bodybuilding world. However, in my experience, it is only necessary to be used for the last 4-6 weeks, to eliminate excess estrogen and water retention. After using Letrozole I recommend staying away from any estrogen suppression for at least a month to try to normalize the body.


Letrozoles lowers estrogen levels in postmenopausal women, which may slow the growth of certain types of breast tumors that need estrogen to grow in the body. Letrozoles is an aromatase inhibitor. It works by reducing the total amount of estrogen produced primarily in the body. This helps to starve cancer cells by depriving them of estrogen.


Letrozoles is also used to help prevent the cancer from returning. Some breast cancers are made to grow faster by a natural hormone called estrogen. Letrozoles decreases the amount of estrogen the body makes and helps to slow or reverse the growth of these breast cancers.


Letrozole  Dosages and Half Life


 

The half life is approximately 2-4 days. Dosages vary quite a bit, 0.25mg up to 1mg every day or every other day is a good starting dose. It’s best to be conservative with the dosage because if you overdose the sides can be harsh.
