Frequently Asked Questions

Do you sell liquidex, arimidex, or oranastrazole?

Short Answer

Yes, look for Anastrozole.

Long Answer

Anastrozole (Altarz, Arimidex) is a breast cancer medication. It may be prescribed as an initial treatment or to treat breast cancer that has continued to progress after taking Tamoxifen. It's primarily used to treat hormone receptor-positive breast cancers that are fueled by estrogen.

An enzyme in the body called aromatase is used to produce estrogen in the ovaries and in other tissues. After menopause when women stop menstruating, the ovaries no longer produce estrogen but small amounts are still produced elsewhere. In men, aromatose converts some testosterone into estrogen.

Anastrozole is an aromatase inhibitor. It works by blocking the action of aromatose, thereby lowering the production of estrogen in the body and slowing down tumor growth.

Anastrozole is only presribed to post-menopaulal women since it has no effect on ovarian production of estrogen. It does, however, suppress estrogen production in the rest of the body. Breast cancer in men is rare but in cases of hormone receptor-positive breast cancer, Anastrozole may be prescribed.

Off-Label Uses

Anastrozole may be prescribed to treat other conditions:

  • Prevention of breast cancer in women who are at high risk of developing the disease
  • Offset the effects of excess testosterone in bodybuilders, especially those who take anabolic steroids
  • Pubertal gynecomastia (growth of breast tissue in adolescent boys)
  • Precocious puberty (begins before age 8 in girls and age 9 in boys)
  • To increase adult height in short children
  • Prostate cancer
  • Ovarian cancer
