Consult a physician before taking any medication. What does "anti-estrogen" mean? How are anti-estrogens like Cytadren, Clomid, and Nolvadex different from each other? Is Proviron an anabolic steroid, or not? Anti-estrogens are drugs which act to reduce estrogenic activity in the body. This can be done either by reducing the amount of estrogen, or by reducing the mexican anabolics back muscles activity of whatever estrogen is present. Competitive aromatase inhibitors, such as Cytadren, Arimidex, and probably Proviron, bind to the same binding site on the aromatase enzyme that testosterone does. By doing this, they allow less testosterone to bind to aromatase. So, less testosterone is converted to estradiol (estrogen). Here's an important thing: the effectiveness of competitive inhibitors decreases as the amount of the normal substrate increases. Suppose that you had equal amounts of inhibitor and normal substrate in the blood, steroid articles back muscles and they bound to the enzyme equally well. Then the inhibitor would at any moment be taking up half the sites that the normal substrate otherwise would, so it would reduce conversion rate by 50%. But if the amount of substrate is increased 10 times while the amount of inhibitor remains the same, then the inhibitor would be outcompeted by the more numerous substrate molecules. It would therefore be rather ineffective. For example, with more testosterone molecules available, and back muscles back muscles similar
