Anastrozole, commonly known as Arimidex, is a powerful oral drug manufactured by Balkan Pharmaceuticals. It plays a significant role in the management of various medical conditions and is widely used in the realm of bodybuilding and sports performance enhancement. In this article, we will delve into the general description, indications, contraindications, uses in bodybuilding and sport, medical action, combination with other drugs, recommended dosage, and potential side effects of Anastrozole.

General Description:

Anastrozole, often sold under the trade name Arimidex, belongs to a class of medications called aromatase inhibitors. It is primarily used to treat postmenopausal women with breast cancer. This medication works by lowering the levels of estrogen in the body, which can slow down the growth of hormone-receptor-positive breast tumors.


  1. Breast Cancer: Anastrozole is predominantly prescribed for postmenopausal women diagnosed with hormone receptor-positive breast cancer. It helps in preventing the recurrence of breast cancer by inhibiting the production of estrogen, a hormone that can stimulate the growth of cancer cells.


Despite its effectiveness, Anastrozole is not suitable for everyone. It is contraindicated in the following cases:

  1. Pregnancy: Anastrozole should not be used during pregnancy as it can harm the developing fetus.
  2. Pre-menopausal Women: This medication is designed for postmenopausal women and is generally not recommended for those who have not reached menopause.
  3. Allergic Reactions: Individuals with a known allergy to Anastrozole or any of its ingredients should avoid using this medication.

Uses in Bodybuilding and Sport:

Anastrozole has also found its way into the world of bodybuilding and sports performance enhancement. Athletes and bodybuilders often use it for the following purposes:

  1. Estrogen Control: Anastrozole is employed to control estrogen levels in the body. High estrogen levels can lead to unwanted side effects in bodybuilders and athletes, such as gynecomastia (the development of breast tissue in males) and water retention. By reducing estrogen, Anastrozole helps in achieving a leaner and more defined physique.

Medical Action:

The primary action of Anastrozole lies in its ability to inhibit the enzyme aromatase. Aromatase is responsible for converting androgens (male hormones) into estrogen (female hormones) in the body. By blocking this conversion, Anastrozole effectively reduces estrogen levels, which is crucial in the treatment of breast cancer and in bodybuilding for estrogen control.

Combining with Other Drugs:

In bodybuilding, Anastrozole is often combined with other drugs to enhance its effectiveness. Some common combinations include:

  1. Testosterone Replacement Therapy (TRT): Bodybuilders on TRT may use Anastrozole to counteract the potential increase in estrogen levels resulting from exogenous testosterone administration.
  2. Aromatizable Steroids: When using steroids that have a high potential for aromatization (conversion to estrogen), such as testosterone or Dianabol, Anastrozole is frequently included in the stack to prevent estrogen-related side effects.


The recommended dosage of Anastrozole can vary depending on individual needs and the specific context in which it is used. For breast cancer treatment, the typical dose is 1 mg per day. In bodybuilding, dosages can range from 0.5 mg to 1 mg every other day or as needed to control estrogen levels. It’s essential to start with a lower dose and adjust as necessary to avoid over-suppression of estrogen.

Side Effects:

While Anastrozole is generally well-tolerated, it can cause side effects, including:

  1. Joint Pain: Some individuals may experience joint pain as a side effect of Anastrozole.
  2. Hot Flashes: Hot flashes are a common side effect, particularly in postmenopausal women.
  3. Nausea: Nausea and upset stomach can occur in some users.
  4. Bone Health: Prolonged use of Anastrozole may lead to a slight increase in the risk of osteoporosis due to reduced estrogen levels. Regular bone density checks and supplementation with calcium and vitamin D may be necessary.


Anastrozole, sold as Arimidex and manufactured by Balkan Pharmaceuticals, is a versatile medication with applications in both the medical field and the world of bodybuilding and sports performance enhancement. Whether you’re a postmenopausal woman in need of breast cancer treatment or an athlete seeking estrogen control, understanding its general description, indications, contraindications, uses, medical action, combination with other drugs, recommended dosage, and potential side effects is crucial for safe and effective usage. Always consult with a healthcare professional before starting Anastrozole or any other medication to ensure it’s the right choice for your specific needs and circumstances.
