What is Letrozole?
Letrozole, marketed under the brand name Letrodex, is an aromatase inhibitor primarily used in the medical field to treat hormone-receptor-positive breast cancer in postmenopausal women. It is also popular among bodybuilders for its ability to manage estrogen levels during anabolic steroid cycles.

Letrozole works by inhibiting the aromatase enzyme, which is responsible for converting androgens into estrogens. By reducing estrogen production, letrozole helps prevent estrogen-related side effects and supports a favorable hormonal balance.
