Anastrozole(Arimidex)

The functions and traits of Arimidex although powerful are extremely simple. As an AI Arimidex functions by blocking the aromatase enzyme, which is in turn responsible for the production of estrogen. By inhibiting the aromatase process, Arimidex will lower the body’s serum estrogen levels; in fact, a total suppression of estrogen by 80% has been well noted with this AI. This will prove very beneficial to numerous breast cancer patients and extremely valuable to many anabolic steroid users.

Arimidex also has the ability to stimulate the release of Luteinizing Hormone (LH) and Follicle Stimulating Hormone (FSH), two hormones essential to natural testosterone production. This has led some physicians to use the AI in low testosterone treatment plans in place of testosterone, but it’s generally not the best choice. Arimidex in a low testosterone plan is generally better served in conjunction with testosterone therapy. We will look more into this when we discuss the effects of Arimidex later on.

Effects of Arimidex:
As an anti-estrogen, Arimidex is valuable to the breast cancer patient as many forms of breast cancer feed off of the estrogen hormone. While perhaps an oversimplification, by administering Arimidex the effect starves the cancer. For decades Nolvadex was used for this purpose. Nolvadex has the ability to bind to the estrogen receptors, which in turn prevents estrogen from binding. However, AI’s like Arimidex actively inhibit the production of estrogen and reduce the actual amount of circulating hormone. In short, there is no estrogen available to cause damage to the breast cancer patient. In recent years, Arimidex has become the leading anti-estrogen in the treatment of hormone receptor-positive breast cancer, especially among post-menopausal women. Once the cancer has subsided, it is not uncommon for Nolvadex to be introduced in order to keep the cancer at bay.

For the anabolic steroid user, the effects of Arimidex are greatly appreciated in its ability to protect against estrogenic related side effects. Many anabolic steroids have the ability to promote estrogenic side effects due to the testosterone hormone’s interaction with the aromatase enzyme. As aromatization occurs, estrogen levels rise and this can lead to gynecomastia and excess water retention. When excess water retention becomes severe, this can also promote high blood pressure. Not all anabolic steroids aromatize, and as such, not all can lead to estrogenic related effects. However, many common steroids do carry the ability to promote estrogenic activity including Dianabol, all forms of Nandrolone and Boldenone to a degree and of course, all forms of testosterone heavily.

By including Arimidex in an anabolic steroid cycle that contains aromatizing steroids, the individual can protect against gynecomastia and water retention. This will also protect against high blood pressure. Some steroids can still cause high blood pressure without water retention, but heavy excess water retention is the number one culprit of high blood pressure among anabolic steroid users. Without question, AI’s like Arimidex are the most effective anti-estrogens for combating estrogenic related side effects.
As a testosterone stimulating compound, Arimidex can be appealing for low testosterone treatment plans and for Post Cycle Therapy (PCT) for anabolic steroid users. In the case of low testosterone treatment, it’s often not enough. However, it can still be beneficial in conjunction with exogenous testosterone therapy in protecting against estrogenic side effects. As for PCT use, some will attempt it and it can have a positive effect, but it is generally not recommended. The main purpose of a PCT plan is to stimulate natural testosterone production in order to protect lean muscle tissue, keep body fat under control and promote a better state of health. However, the overall purpose is normalization, which cannot be reached when using Arimidex post cycle due to the tremendous estrogen reduction. Although high levels of estrogen can be problematic, some is necessary to proper bodily function, especially regarding the immune system and cardiovascular health.
