Aromasin is a recently developed and potent anti-estrogen medication that works by preventing the conversion of other molecules in the body to estrogen. It is used in a clinical setting in the treatment of post-menopausal breast cancer patients after other treatments have failed. As estrogen is produced in various locations around the body after a woman has gone into menopause (rather than from the ovaries in a premenopause woman), Aromasin acts on those enzymes. Due to the fact that many steroids are converted into estrogen in the body’s tissue, Aromasin has proven popular in the bodybuilding community.
Many anabolic and androgenic steroids are converted into estrogen in the body and, for men, this results in undesirable side effects such as gynecomastia, fat buildup, and water retention (which can hide muscles under a layer of definition-softening water). Aromasin may even help some to lose body fat, boost testosterone levels (up to 60%) and increase somatomedin (which is anabolic in and of itself). Despite its testosterone boosting properties Aromasin is not generally used in post-cycle regimes and is at its best on a full cycle.
