Enhances proper testosterone and oestrogen levels. Helps maintain healthy muscle tissue. Aromastat is an all-natural blend of herbs shown in clinical studies to inhibit the enzyme aromatase. In men aromatase activity increases with age converting what little testosterone that is left into estrogen. It is perhaps this event that is most responsible for the many symptoms of male menopause and possibly even an enlarged prostate and prostate cancer. In women most of the research on aromatase inhibitors addresses the treatment of clinical conditions known to be linked with excess oestrogen production or sensitivity. In addition aromatase inhibitors are used by the bodybuilding community to increase lean muscle mass and decrease body fat.
