It does not cause hormone levels to fluctuate; although the application is more frequent there is less risk for adverse side effects.

It is essential to use antiestrogens to control estrogen levels in the bloodstream decreasing the risk of gynecomastia, water retention and body fat gain. These type of products have no hepatotoxic effects in comparison to oral substances.
