In studies that have been done, Arimidex has been shown to reduce estrogen in the body by roughly 50%. This is a good balance for bodybuilders , because some estrogen is needed in order for the full anabolic benefits of the steroids being taken to be achieved. These results are typically the same with a dosage of .5 mg a day as they are with a dosage of 1 mg a day, meaning that in most cases, a half tablet a day will be sufficient for estrogen control throughout cycle.
Typically, bodybuilders using Arimidex will begin taking it the day they start their cycle, and will run it throughout the duration of steroid administration. It is also important to point out Arimidexâs ability to increase testosterone in the body. Some studies have shown that natural testosterone levels have increases as much as 60% after the use of this substance for 7 days. Because of this, bodybuilders find this drug extremely effective during PCT where as they are trying to elevate natural levels as much as possible in order to avoid a post cycle "crash".
It is generally recommended that upon discontinuance of steroid use, that one continue to run Arimidex throughout the duration of their PCT regime. (4-6) weeks
