For breast cancer treatment. Some breast cancers need the hormone oestrogen to grow. In women who have been through the menopause, the main source of oestrogen is through the change of sex hormones called androgens into oestrogen. An enzyme called ‘aromatase’ is needed for this change to occur. Letrozole works by inhibiting (or blocking) this enzyme, then reduces the amount of oestrogen in your body, which slows the growth of the cancer cells.
For infertility treatment. Letrozole is a recent addition to the drugs being used for fertility treatment. Fertility drugs are often used in infertility treatments.
For athletics and bodybuilding. In athletics and bodybuilding, it is used as an ancillary compound within anabolic steroid cycles for its estrogen reducing properties, and has the additional benefit of modestly increasing testosterone levels.
I’ve been taking this product for 7 years now. After 7 years of several different medicines to try to stop the growth of the tumors, this product is the only one which worked for me. I’m happy with results so far. Some side effects not enough to be concerned about. I highly recommend this product for those who want longevity without losing your quality of life. –Charles
