What are the benefits of anti-estrogen supplements?

According to IllPumpYouUp.com, anti-estrogen supplements are beneficial during post-cycle therapy. In post-cycle therapy, testosterone levels are low so the body compensates with higher levels of estrogen production. Anti-estrogen supplements stop this increase in estrogen production and increase testosterone production to help keep gains.

An additional benefit to anti-estrogen supplements is reducing bloating and gynecomastia, a condition that results in puffy and itchy nipples or breasts. It is not recommended to take anti-estrogen supplements as a standalone product to increase testosterone levels. Some side effects of anti-estrogen supplements are acne and an increase in sex drive. HealthTap states that anti-estrogen supplements are not beneficial as a nutritional supplement because they interfere with bone metabolism.
