1mg x 28 tablets Arimidex (anastrozole) (boxes and brands may vary) Arimidex (anastrozole) is an Ai (aromatase inhibitor) that was originally developed for the treatment of advanced breast cancer in women. Up to this point Nolavdex and proviron have been our weapons against excess estrogen. These drugs especially in combination, do prove quite effective. But Arimidex (anastrozole) appears to the job much more efficiently, and with less hassle. Its use is only now catching on, but early reports have been excellent. A single tablet daily, the same dose use clinically, seems to be all one needs for an exceptional effect. Arimidex can effectively block the aromatisation of strong androgens such as dianabol and testosterone. In combination with Propecia, we have a great advance . With the one drug halting estrogen conversion and the other blocking 5-alpha reduction (testosterone, methltestosterone and Halotestin only). Here the strong androgen testosterone could theoretically provide incredible muscular growth, while at the same time being as tolerable as nandrolone. Additionally the quality of the muscle should be greater, the athlete appearing harder and much more defined without holding excess water. HDL CHOLESTEROL There are some concerns with using an aromatase inhibitor such as this during prolonged steroid treatment however. While it will effectively reduce estrogenic side effects, it will also block the beneficial properties of estrogen becoming apparent . Studies have clearly shown that when an Ai is used in conjunction with testosterone , suppression of HDL (good) cholesterol becomes more pronounced. Apparently estrogen plays a role in minimising the negative impact of steroid use. Competitors on the other hand are likely to welcome this item. It can ward off the side effects of strong androgen therapy much better than Nolvadex and/or Proviron, making heavy cycles much more comfortable. For most competitors an Ai like arimidex is a must in their arsenal when on a contest prep diet.
