This says does over 1/2 gram, 500mg is obviously right at the cut off line?


A large percentage of those side effects occur from the body´s ability to turn testosterone into estrogen via a metabolic pathway mediated by the aromatase enzyme. This process, known as aromatization causes a portion of testosterone to be converted to estrogen. Aromatase Inhibitors (Arimidex and Letroaole, for example) can combat this very effectively, and are usually necessary with doses over ˝ a gram per week.
