To begin with, Arimidex is not medically recommended for use in body builders or for the treatment of any medical disorder in men. All the data about Arimidex on body builders has been empirically derived by trial and error.
One of the chief reasons why Arimidex is used by body builders is to decrease the side effects which usually occur after the use of other anabolic steroids. The majority of anabolic steroids will cause breast enlargement, loss of hair and water retention. Arimidex with its ability to block the synthesis of estrogen can alleviate some of these embarrassing and obvious side effects of anabolic steroids. Plus, it has been observed that the 1mg dose of Arimidex can also increase the levels of testosterone. In the past, most body builders used drugs like Nolvadex or Proviron against the excess estrogen, but many prefer Arimidex because its actions are rapid and effective. Individuals who use Arimidex for this purpose suggest a starting dose of 0.25 mg/day. Only if no response is seen after a few months, should the dose be increased to 0.5-1.0 mg. The great thing about Arimidex is that it can be used with a variety of anabolic steroids.
However, a word of caution. Anyone who takes Arimidex should get routine measurements of the estrogen levels in the blood. Complete suppression of estrogen can lead to decreases in HDL (good cholesterol). And this can lead to premature development of heart disease.
Concerns about Arimidex
Arimidex is not supposed to be taken by women who are pregnant because there is a concern that it may cause damage to the fetus. While all these studies have been done in animals, there is concern that the drug may have similar effects in human pregnant female. If a pregnant female does take Arimidex, the patient should be appropriately counseled on the risk versus the benefit because there is potential to lose the fetus.
Arimidex in general is never administered to premenopausal females. All women who do receive the drug always require a pregnancy test first.
All women who take Arimidex should be carefully followed up and their bone density regularly assessed. The drug is known to worsen osteoporosis and increase the incidence of fractures. Arimidex also causes an increase in the levels of blood cholesterol.
In animals at least, the drug has been shown to induce cancers at very high doses. This is the chief reason why Arimidex should not be taken for more than 5 years in humans.
