Anastrozole is a potent AI that prevents the conversion of testosterone to estrogen. It’s used during steroid cycles to control estrogen-related side effects such as gynecomastia, water retention, and high blood pressure.
As a third-generation AI, anastrozole is highly effective at reducing estrogen levels, but this can be a double-edged sword. While it prevents estrogenic side effects, completely crashing estrogen can lead to joint pain, mood issues, and impaired muscle growth.
The key to using anastrozole successfully is finding the minimum effective dose that controls estrogen symptoms without completely eliminating estrogen’s beneficial effects. Most users find that less is more with this compound.
