Avoid Aromatase Inhibitors. Aromatase-inhibiting drugs counter estrogenic side effects by preventing the production of estrogen in the body. While an effective practice, they also deprive the body of a hormone that is important to cardiovascular health. In particular, estrogen supports the production of good (HDL) cholesterol, which means that aromatase inhibitors may inadvertently increase the cardiovascular strain of a steroid cycle. If estrogenic side effects are apparent and a reduction or elimination of the offending steroid(s) is not considered an option, the SERM (Selective Estrogen Receptor Modulator) drug Nolvadex could be used instead. This drug offers partial estrogenic action in the liver, which may allow
it to counterer estrogenic side effects without the same negative shift in cholesterol.
