Aromasin in Bodybuilding

The world of bodybuilding is a dynamic landscape where athletes and enthusiasts continually explore new strategies to enhance their physical gains. Among the various tools and supplements employed, aromatase inhibitors, specifically Aromasin (Exemestane), have garnered attention for their potential impact on hormone regulation and muscle-building outcomes. Originally designed for breast cancer treatment, Aromasin’s relevance in bodybuilding stems from its ability to influence estrogen levels and consequently affect muscle definition, water retention, and fat accumulation.

Understanding Aromatase Inhibitors

Aromatase inhibitors are pharmaceutical compounds that interact with the enzyme aromatase, a key player in the conversion of androgens (such as testosterone) into estrogens. This interaction effectively reduces the production of estrogens in the body, leading to lower circulating estrogen levels. While aromatase inhibitors have a well-established role in breast cancer therapy, their potential implications for bodybuilders have prompted exploration into their effects on muscle development and overall physique.

Effects on Estrogen Levels

Estrogen, despite being predominantly considered a female hormone, has various functions in both genders. In males, it contributes to bone health, lipid metabolism, and cardiovascular maintenance. However, excess estrogen in men can lead to undesirable outcomes such as gynecomastia, bloating, and increased body fat. Bodybuilders who employ aromatase inhibitors like Aromasin aim to mitigate these effects by maintaining optimal estrogen levels for their objectives.

The benefits of Aromasin in Muscle Building

The interplay between estrogen and muscle growth is complex. While high estrogen levels can influence fat storage and water retention, they also contribute to muscle tissue maintenance and repair. This raises an important consideration for bodybuilders: completely suppressing estrogen may not be conducive to their goals. Some individuals believe that using Aromasin to carefully control estrogen levels could foster an environment that promotes lean muscle gains, reduced water retention, and improved vascularity.

Side Effects of Aromasin

The use of aromatase inhibitors in bodybuilding is not without risks and challenges. Determining the appropriate dosage and duration requires precision, as excessively low estrogen levels could lead to adverse health effects. Aromasin can negatively impact cholesterol levels by reducing “good” cholesterol (HDL) and increasing “bad” cholesterol (LDL). Moreover, estrogen is important for maintaining bone density, and prolonged use of aromatase inhibitors might increase the risk of bone-related issues, especially in older individuals.

Balancing Hormones and Gains

Bodybuilders who consider using Aromasin or similar aromatase inhibitors should approach the decision with careful consideration. Striking the right balance between hormone manipulation and muscle-building goals is crucial. Medical supervision and consultation with professionals who understand both bodybuilding and endocrinology are essential. A comprehensive approach to bodybuilding encompasses tailored training programs, precise nutritional strategies, and sufficient recovery periods.

Aromasin and anabolic steroids

Aromasin (Exemestane) is commonly associated with its role as an aromatase inhibitor, used primarily in the treatment of hormone-receptor-positive breast cancer in postmenopausal women. However, in the realm of bodybuilding and anabolic steroid use, Aromasin is often used as part of a strategy to manage estrogen levels during steroid cycles.

When bodybuilders use anabolic steroids, such as testosterone or others that increase muscle growth, there is often a concurrent increase in estrogen levels due to the conversion of androgens into estrogens via the aromatase enzyme. This can lead to side effects described above. To mitigate these effects, bodybuilders add aromatase inhibitors like Aromasin into their steroid cycle.

The goal of using Aromasin alongside steroids is to reduce estrogen levels and minimize estrogen-related side effects. By inhibiting the aromatase enzyme, Aromasin decreases the conversion of androgens into estrogens, thus potentially helping individuals maintain a more lean and defined physique during their steroid cycles.

However, it’s important to note that manipulating estrogen levels through the use of aromatase inhibitors can be a delicate process. Estrogen plays a vital role in various physiological functions, including bone health and lipid metabolism. Completely suppressing estrogen (common mistake of beginners) might lead to unintended health consequences, such as negative impacts on cholesterol levels and bone density. It can also decrease your appetite and bring a pain in joints (due to the reduction of water in the body).

To avoid this, it is essential to follow correct dosages of Aromasin during a steroid cycle.

The dosages of Aromasin during a steroid cycle

The dosages of Aromasin (Exemestane) can vary depending on the specific steroids being used during a cycle, body composition, hormone levels, and tolerance.

For bodybuilders and athletes who are considering using Aromasin as part of their steroid cycle to manage estrogen levels, typical dosages range from 12.5 mg to 25 mg per day. However, dosages should be adjusted based on individual response and Blood Tests. You can read more about the precise determination of dosages of aromatase inhibitors based on blood test in the articles:

Aromatase Inhibitors

Remember that the goal is not to completely suppress estrogen, but to maintain a balanced and controlled level that minimizes estrogen-related side effects without compromising overall health. Using too much Aromasin could lead to excessively low estrogen levels, which can have negative impacts on your body (described above).

Here are some general considerations for Aromasin dosing:

1) Start Low

Begin with a low dose, such as 12.5 mg every other day, and assess how your body responds. Some individuals might require higher doses, while others might need less.

2) Monitor and Adjust

Regularly monitor your estrogen levels and any potential side effects. Adjust the dosage as needed based on the blood tests results and how you’re feeling.

3) Cycle Duration

Aromasin might not need to be used throughout an entire steroid cycle. Use it as needed, starting when estrogen-related symptoms arise and discontinuing it once the steroid cycle is complete.

4) Post-Cycle Therapy (PCT)

If Aromasin is used during a post-cycle therapy to help restore natural hormone production, dosages might be adjusted accordingly. PCT is crucial to help the body recover its natural hormonal balance after a steroid cycle.

It is important to mention that self-administering Aromasin without proper medical supervision can lead to serious health risks and unintended consequences. Hormone manipulation is a complex process that requires careful consideration and expertise. Always prioritize your health and well-being when making decisions about supplementing with Aromasin or any other substances.

How to choose Aromasin

Choosing a place where to buy Aromasin, it is better to choose a pharmacy instead of anabolic steroid shops in the Internet. It is simple, you will have less chances to meet a fake.

There are a lot of Aromasin manufacturers but I would say it is preferable to choose the most famous one called Pfizer.


Aromasin’s integration into the realm of bodybuilding hinges on its potential to influence estrogen levels and impact physique outcomes. However, it’s vital to approach the use of aromatase inhibitors with caution and informed decision-making. The multifaceted role of estrogens in the body demands a nuanced approach that prioritizes health and long-term well-being.
