Absolutely not. In fact, the opposite is true. Tribestanol may normalize estrogen levels in the body. If your estrogen levels are too high, it will decrease them to normal levels. And if they are too low, Tribestanol will raise them to normal levels. Most people are worried about heightened estrogen levels, but if they are too low they can go into a catabolic state more easily. Low estrogen levels relate to low testosterone levels. If testosterone levels are low, the body will balance hormonal levels by also lowering estrogen levels. Using Tribestanol will increase testosterone levels around 40%, while at the same time normalize estrogen levels to enhance anabolic mechanisms for maximum performance and growth.
