you need estrogen. you need some bloat.

It is wrong to think, however, that estrogen and its effects (particularly water and fat retention) are absolutely detrimental to bodybuilding. Remember that this hormone is also responsible for muscle strength and gains. Consequently, it minimizes the occurrence of injury as it improves the ability of muscle fibers to withstand contractile tension or stress. Notice that one of the side effects of Arimidex use (as mentioned below) is the likely occurrence of fractures, a major drawback of this drug. This is because when Arimidex effectively blocks the formation of estrogen, it effectively blocks the benefits of this hormone as well. This is why many still decide for estrogen receptor antagonists like Nolvadex and Clomid because these drugs allow some estrogen activity in the body.
Further, aromatase inhibitors like Arimidex have the tendency to completely suppressed estrogen activity, including its positive effect on cholesterol levels in the body. Arimidex is known to decrease HDL (high-density lipoprotein), or what is commonly known as the ‘good’ cholesterol.
