Letrozole is a potent aromatase inhibitor that reduces estrogen levels in the body by blocking the conversion of testosterone into estrogen.

It is widely used both in clinical settings and off-label contexts, including by men during anabolic steroid cycles and by women undergoing fertility treatment.

For men on anabolic cycles, Letrozole can help manage estrogen-related side effects caused by elevated testosterone levels.

In women, it is commonly prescribed to stimulate ovulation and support fertility by encouraging the release of eggs.

Benefits:

Helps control estrogen levels during anabolic cycles

Reduces risk of estrogen-related side effects (e.g. water retention, gynecomastia)

Supports ovulation and fertility in women

May improve hormonal balance when used appropriately

Main Side Effects:

Joint pain or stiffness

Fatigue

Letrozole should always be used with caution and under professional guidance, as improper use can significantly impact hormone balance in both men and women.
