Aromatase Inhibitors (AI)

Many anabolic steroids have the ability to aromatase and lead to excess estrogen, which in turn can lead to some of the most commonly associated side effects of anabolic steroid use. Aromatase Inhibitors (AI) function by blocking the aromatase enzyme, which is in turn responsible for the production of estrogen. By inhibiting the aromatase process, AI will lower the body�s serum estrogen levels up to 80%. By including Aromatase Inhibitors (AI) treatment in an anabolic steroid cycle that contains aromatizing steroids, the individual can protect against gynecomastia, water retention and consequently high blood pressure.
