First, Testosterone pellets are not the way to go.  Historically, these will go the way of all the implantable contraceptive devices.  However, the conclusion of this study is good and confirms the benefit of anastrazole to inhibit aromatase activity and help to maintain Testosterone levels.

Study finds that Testosterone with or with the aromatase inhibitor anastrazole as a pellet reduced breast cancer risk.  This conclusion should be taken with caution.  It is well know that abnormal breast tissue, breast cancer, highly expresses aromatase activity which would increase Testosterone to estradiol production.  This would feed any growing tumor.  But, this study finds protection.  The failure of this study is the measurement of hormone levels.

ER beta expression and the ratio of ER alpha/ER beta is important in prognosis and effectiveness of SERM therapy like tamoxifen.  This study looked at the aromatase inhibitor anastrazole as well.

Letrozole has more AI activity than anastrozole.
