Wondering whether to choose Aromasin vs Arimidex?
This article breaks down their key differences, benefits, and side effects to help you understand which might be better for your needs.
Key Takeaways
- Aromasin and Arimidex are both aromatase inhibitors, but they work differently. Aromasin binds to the enzyme permanently, cutting estrogen levels by up to 85%, while Arimidex only blocks it temporarily, reducing levels by around 70%.
- Both drugs are not FDA-approved for bodybuilding, with the potential for side effects like joint pain and bone density loss. It’s important for athletes to note they are banned by anti-doping agencies.
- Everyone responds differently, so it’s a good idea to check with your healthcare provider before using either medication, especially for any off-label use.
Breaking down the differences between Aromasin vs Arimidex
Many coaches and fitness enthusiasts suggest trying Aromasin, while others favour Arimidex. Researching these options before starting a cycle can help you make a well-informed choice.
So, what makes them different? Here are the key differences:
- Both are aromatase inhibitors, but they work in different ways.
- Aromasin, aka exemestane, irreversibly binds to and inactivates the aromatase enzyme, which is responsible for converting androgens to estrogens.
- In contrast, Arimidex blocks the enzyme without permanently binding to it, impacting both its effectiveness and side effects.
Individual responses vary, meaning what works for one person might not work for another. Aromasin is frequently chosen because it can lower estrogen levels by up to 85%, effectively controlling estrogen-related side effects like gynecomastia.
Arimidex generally reduces estrogen levels by around 70% within 24 hours. These differences underscore the need for personalized medical advice before starting either medication.
Overview of Aromasin and Arimidex
Both Aromasin and Arimidex belong to a class of medications known as aromatase inhibitors, which are primarily used to treat breast cancer and to treat advanced breast cancer by reducing estrogen levels in the body. For bodybuilders and athletes, however, these drugs serve a different purpose. Controlling estrogen levels helps manage side effects related to anabolic steroid use, such as gynecomastia and water retention.
Bodybuilders often use Arimidex (Anastrozole) off-label to manage estrogen levels. It blocks the enzyme aromatase, preventing the conversion of testosterone to estrogen. This action reduces estrogen-related side effects and enhances muscle hardness.
On the other hand, Aromasin (Exemestane) is a steroidal aromatase inhibitor that can lower estrogen levels by an average of 85% and potentially increase testosterone levels. Both drugs are not FDA-approved for bodybuilding purposes and are banned by the World Anti-Doping Agency.
How Aromasin Works
Aromasin, also known scientifically as exemestane, works by irreversibly binding to and inactivating the enzyme aromatase. This enzyme converts androgens to the hormone estrogen. By blocking this enzyme, aromasin significantly reduces estrogen levels in the body, potentially up to 85%. This reduction in estrogen can lead to an increase in testosterone levels, similar to the effects of testosterone replacement therapy.
Aromasin is highly selective, not affecting other steroidogenic enzymes or adrenal hormone production. It reaches maximum effectiveness 2-3 days after administration and has a half-life of about 24 hours. In young adult males, it has been shown to suppress estradiol (E2) by 35% and estrone (E1) by 70%.
How Arimidex Works
Arimidex (Anastrozole) functions by inhibiting the aromatase enzyme, which decreases estrogen production in the body. This makes it highly effective in managing estrogen-related side effects of anabolic steroid use, such as gynecomastia and water retention. Arimidex can reduce estrogen levels by approximately 70% within 24 hours of administration, with levels remaining suppressed for up to 6 days after stopping treatment.
Typically, dosages for bodybuilding purposes range from 0.5mg to 1mg per day, though this use is not medically recommended or approved. Like Aromasin, Arimidex does not affect other steroidogenic enzymes or adrenal hormone production.
Comparing Effectiveness
Comparing the effectiveness of Aromasin and Arimidex involves considering their impact on estrogen levels and their ability to prevent side effects. As mentioned earlier, both drugs effectively manage estrogen levels, though through different mechanisms. Arimidex blocks the aromatase enzyme, while Aromasin irreversibly binds to and inactivates it. This fundamental difference can influence their effectiveness and side effects.
Aromasin may reduce estrogen levels by up to 85%, potentially more than Arimidex. This makes it highly effective in controlling estrogen-related side effects such as gynecomastia. On the other hand, Arimidex typically reduces estrogen levels by around 70% within 24 hours of administration. While both drugs can increase endogenous androgen biomarkers, including testosterone, which may improve athletic performance, Aromasin users have demonstrated an increase in lean body mass and free testosterone levels and a decrease in SHBG levels (sex hormone-binding globulin is a protein produced mainly in the liver that binds to and transports sex hormones in the blood) compared to non-users.
Common Side Effects of Aromasin
While effective, aromasin has a range of potential side effects that bodybuilders and athletes should be aware of. Common side effects include hot flashes, increased sweating, and changes in mood or energy levels, which can affect performance. Other side effects include joint and muscle pain, headaches, insomnia, and increased appetite, which can potentially lead to weight gain.
In addition to these, Aromasin can increase cholesterol levels and liver function changes. It may also cause bone density loss, increasing the risk of fractures and osteoporosis.
Furthermore, Aromasin can lead to high blood pressure, hair loss, and a potential negative impact on insulin sensitivity in skeletal muscle.
Considerations for Liver and Kidney Problems
If you have a liver problem such as hepatitis or cirrhosis, it’s crucial to inform your doctor before using Aromasin. Liver problems may increase the amount of the drug in your body, potentially leading to heightened side effects. It’s important to ask your doctor if Aromasin is the right choice for you, considering your liver health.
Similarly, if you have kidney problems, discussing this with your healthcare provider is essential. Kidney issues can also affect how your body processes Aromasin, impacting its effectiveness and safety. Your doctor can help determine the appropriate course of action and whether Aromasin is suitable for your condition.
Vitamin D Supplement
Before you start taking Aromasin, it’s a good idea to get your doctor to check the level of vitamin D in your blood. If your level is low, they may recommend taking a vitamin D supplement. Your doctor may also suggest other medications to prevent bone loss. If you have questions about your vitamin D level and taking Aromasin, talk with your healthcare provider to ensure you are taking the necessary steps to maintain bone health while on this medication.
Alcohol and Aromasin: A Cautionary Note
While taking Aromasin, it’s important to be mindful of alcohol consumption. Some side effects of Aromasin, such as trouble sleeping, headaches, and nausea, can overlap with those caused by excessive alcohol intake. Therefore, drinking alcohol while on Aromasin could potentially worsen these side effects, leading to increased discomfort and impacting overall well-being. It’s advisable to consult with your healthcare provider about alcohol use during Aromasin treatment to ensure safe and effective management of side effects.
Common Side Effects of Arimidex
Bodybuilders and athletes should also be mindful of Arimidex’s side effects. Common side effects include reduced bone mineral density, headaches, and hot flashes. Individual reactions to Arimidex can vary, and some users may experience more severe side effects, such as joint and muscle pain, including back pain and increased cholesterol levels.
Other side effects include nausea, fatigue, and weakness, as well as mood changes, including depression. Arimidex can also cause skin rash, hair thinning or loss, and sexual side effects such as increased sex drive.
Like Aromasin, using Arimidex for bodybuilding or athletic performance enhancement is not FDA-approved. Additionally, anti-doping agencies have banned its use in competitive sports.
