Normally associated with women, the hormone estrogen is usually of little relevance to men outside the BB’ing lifestyle, but to the steroid initiated, it is a potentially side effect ridden metabolite which must be controlled. Being responsible for gynecomastia, water retention, HPTA suppression, fat gain, mood disturbances, and other undesirable side effects, it is not something we can afford to ignore. Quite simply, elevated estrogen levels can be and often are a consequence of steroid/prohormone use, so if we desire to look and feel better, while maintaining optimal health, we should endeavor to maintain normal levels of this hormone at all times.
There are a few ways to accomplish this. We can either discontinue using any steroid (legal or illegal) capable of estrogen conversion…or we can utilize a class of drugs known as aromatase inhibitors (A.I., for short). In order to understand of how A.I.’s can benefit us, we must first learn how steroids elevate estrogen levels in the first place.
