I am not sure how it affects cholesteral levels but femera is a much better product that liquidex. Understand that it is better for me and may not be for some people. I was on a test/deca/dbol cycle and holding water like a whale. I was using 1-1.5mg of liquidex per day with no results. I got some pnp letrzole and dried up in a week. The stuff really works!
I have to agree that Letrozole is some powerful shit. You can do fractions of a cc per day and get the same effect as 1mg of Arimidex per day. Actually it can be too powerful; you have to learn how your body responds to it.
