Effects of Letrozole:

AI’s like Letrozole are the most effect means at combating estrogenic related side effects. However, they can also have a negative impact on cholesterol. Alone AI’s do not appear to have a strong, negative effect on cholesterol, but when coupled with an aromatizing steroid like testosterone the adverse cholesterol effect is enhanced. For this reason, many will find SERM’s like Tamoxifen Citrate (Nolvadex) should be their first choice in estrogen protection. SERM’s will not negatively affect cholesterol; in fact, SERM’s, while anti-estrogenic, actively act as estrogens in the liver, and in turn, promote healthier cholesterol levels. We’ll look at this in more detail in the side effect section, and while Letrozole can be used without an adverse cholesterol effect, it will take some effort on your part.
