Arimidex is an oral anti-estrogen which contains 2 mg of Anastrozole in each tablet.
As a genuine aromatase inhibitor, Arimidex functions by inhibiting the aromatase enzyme in the body, reducing the amount of estrogen accumulation. This substance offers significant advantages to bodybuilders who utilize aromatizing steroids like testosterone. Such users may experience estrogen-related side effects, including water retention and gynecomastia ("gyno"). However, by taking Anastrozole during their cycle, the likelihood of experiencing these effects is greatly diminished.
Research indicates that Arimidex can lower estrogen levels in the body by approximately 50%. This is an ideal level for bodybuilders, as a certain amount of estrogen is necessary to maximize the anabolic effects of the steroids used. The outcomes tend to be consistent with a daily dose of 5 mg compared to 1 mg, implying that in most instances, taking half a tablet daily will suffice for managing estrogen throughout the cycle.
Bodybuilders typically start taking Arimidex on the first day of their cycle and continue its use for the entire period of steroid administration. It is also worth mentioning Anastrozole's capacity to raise testosterone levels in the body. Some studies have demonstrated that natural testosterone levels can increase by as much as 60% after just 7 days of using this compound. Due to this, bodybuilders find Arimidex highly effective during post-cycle therapy (PCT), as they strive to enhance their natural hormone levels to prevent a "crash" after cycling.
Generally, it is advised that after stopping steroid use, individuals should continue taking Anastrozole throughout the entirety of their PCT regimen, which lasts for about 4-6 weeks.
