Anastrozole is a medication that blocks estrogen production. It is part of the nonsteroidal aromatase inhibitor drug group. Doctors prescribe it for breast cancer treatment, particularly in post-menopausal women with localized breast cancer, or will prescribe to individuals who are at high risk for getting breast cancer for prevention purposes. Anastrozole reduces estrogen hormone levels which in turn will slow the growth of tumors and shrink tumors.
The majority of women with breast cancer are considered ER positive (oestrogen receptor positive), and their cancer cells require estrogen to survive and continue to grow. Before a women reaches menopause, the oestrogen is produced in her ovaries. After menopause, the production of oestrogen in the ovaries decreases drastically and aromatase is used in the body to convert androgens produced by adrenal glands into oestrogen.
Scientific research and clinical trials discovered that aromatase inhibiting drugs could reduce oestrogen levels in postmenopausal women and thus treat (and kill the cells causing) breast cancer.
Where to Buy Anastrozole Without a Prescription
Anastrozole is also a chemical used for research purposes. Many research professionals and scientists buy anastrozole to research breast cancer treatments, or methods of reducing estrogens and estradiol in men. Whenever you are conducting any type of research it is important that your studies are based on high quality products so you can have confidence in your results.
If you’re buying anastrozole for scientific research, you can buy anastrozole without a prescription from reputable sources online, including our site.

Anastrozole has 83-85% bioavailability, is 40% protein binding, and has a biological half life of 48.2 h.
Side Effects of Anastrozole
Prescription side effects of anastrozole are reported to include:
- Joint pain
- Hot flashes
- Mood swings
- Increased risk of heart disease
- Increased risk of osteoporosis
Another medication often used to treat breast cancer, tamoxifen, has some serious side-effects including risks of developing a blood clotting disease and developing womb cancer. Neither of these problems are side effects of anastrozole, but decreased bone density is among the more serious side effects. Now that it is a known side effect of anastrozole, patients are provided with preventative measures for bone problems while being treated with anastrozole. It has been found that within a year of stopping anastrozole treatment, the effects on the bone are eliminated and women’s bone fracture rates return to normal.
Other Uses of Anastrozole
While doctors primarily prescribe anastrozole for post menopausal women who have or are at risk for breast cancer, the medication is also used for men who need to reduce estradiol. Men with high levels of estradiol may have hypogonadism, benign prostatic hyperplasia or gynecomastia. Anastrozole is sometimes prescribed to children with precocious puberty or pubertal gynecomastia to slow the processing of estrogen.
