Letrozole is of particular interest to bodybuilders and athletes. First of all, it has been proven to reduce estrogen levels by 98% or more.
Indeed, less estrogen in the body eliminates the side effects of anabolic steroids such as water retention, gynecomastia, and acne. This makes Letrozole antiestrogens a best seller, even for very difficult cycles. Meanwhile, if you make the bodybuilding competitions Letrozole helps to have lean and striated muscle.
It should be noted that Letrozole, can also be used in post-cycle therapy (PCT) to make a recovery.
In fact Letrozole increases LH and FSH (Hormones which boost the production of Testosterone in the testes).
