Anastrozole, also known as “Arimidex” is a drug primarily used to treat breast cancer in postmenopausal women. In recent years, it has gained popularity among bodybuilders due to its ability to combat the side effects of anabolic steroid use. It belongs to a class of drugs called aromatase inhibitors, which block the production of estrogen. Although Anastrozole is not specifically designed for bodybuilding, some users in the bodybuilding community take it in order to regulate estrogen levels during or after a cycle of anabolic steroids, which can lead to excessive estrogen production.

Anastrozole is a non-steroidal aromatase inhibitor, which works by blocking the conversion of testosterone to estrogen in the body. This is particularly useful for bodybuilders who use anabolic steroids to enhance their performance and physique, as these steroids can often lead to increased estrogen levels. High estrogen levels can cause a range of unwanted side effects, such as water retention, gynecomastia (male breast tissue growth), and fat gain. By using Anastrozole, bodybuilders can mitigate these side effects while still benefiting from the muscle-building effects of anabolic steroids.


In bodybuilding, Anastrozole has been used for the following purposes:

  1. Reduction of estrogen-related side effects: Anastrozole is used to control the estrogen conversion that can occur from the use of anabolic steroids, particularly aromatizing ones. Too much estrogen can lead to side effects, such as gynecomastia (the development of breast tissue in men), water retention, and excessive fat gain. By managing estrogen levels, bodybuilders hope to minimize these side effects and achieve a more lean and muscular physique.
  2. Improved muscle definition: By reducing water retention, Anastrozole can help bodybuilders achieve a more defined, vascular appearance. This is particularly desirable during the cutting phase, where the goal is to shed excess body fat while preserving muscle mass.
  3. Enhanced testosterone levels: Some studies have suggested that Anastrozole may even increase testosterone levels in men, further supporting its use in bodybuilding. Elevated testosterone levels can lead to greater muscle growth, increased strength, and improved overall body composition.
  4. Post Cycle Therapy (PCT): After a cycle of anabolic steroids, some bodybuilders use Anastrozole during their PCT to help restore hormonal balance in their body. The goal is to normalize hormone levels and protect the gains made during the cycle while minimizing any potential side effects.

Examples of Anastrozole Use in Bodybuilding

Preventing Gynecomastia

John, a UK bodybuilder, has been using anabolic steroids for a few months to pack on muscle mass. However, he has noticed the development of excess breast tissue and is concerned about gynecomastia. To combat this side effect, John decides to incorporate Anastrozole into his routine. He starts taking 0.5mg every other day, which successfully prevents further breast tissue growth and even reduces the existing tissue over time.

Reducing Water Retention during Cutting

Sarah, an experienced UK bodybuilder, is in the midst of her cutting phase and wants to achieve a lean, shredded look. As part of her cutting stack, she is using an anabolic steroid that can cause water retention. To combat this issue, Sarah decides to add Anastrozole to her regimen. She takes 0.5mg every other day, which helps her shed excess water weight and achieve the desired level of muscle definition.

Safety and Precautions

While Anastrozole can be beneficial for bodybuilders, it is essential to use it responsibly and under the guidance of a healthcare professional. Overuse of Anastrozole can lead to excessively low estrogen levels, which can cause a range of health issues, such as joint pain, mood swings, and decreased bone density. Always start with a low dose and adjust as needed based on your individual needs and response.

Anastrozole can be a valuable tool for UK bodybuilders looking to minimize the side effects of anabolic steroid use. By reducing estrogen levels, Anastrozole can help prevent unwanted side effects such as gynecomastia, water retention, and fat gain, allowing bodybuilders to achieve their desired physique. However, it is crucial to use Anastrozole responsibly and under the guidance of a healthcare professional to ensure optimal results and minimize potential.
