Estrogen is one of the main ways that testosterone signaling happens, meaning the estrogen level is what can tell your body to produce more or less testosterone. Still, you don't want to reduce it to zero, since estrogen does play a major role in bodily functions like blood pressure, cholesterol and even helps to burn fat. If estrogen levels are high your body will respond by lowering your testosterone levels, which is exactly what the bodybuilder or general health enthusiast doesn't want. Finally, prescription drugs like Nolvadex (R) act like a very weak estrogen in the body, effectively lowering the estrogen activity levels and that will boost testosterone as well.

So, as you see, there is a benefit to the bodybuilder, strength athlete and general health enthusiast to reduce estrogen. Lots of people will pitch you herbal boosters that don't often live up to the hype, but there are some products on the market that will give you the boost you need by retarding estrogen in the body.

In the battle for you to boost your own testosterone to the highest human levels, there are many ways to do it.

Conversely, if you lower estrogen levels and create a deficiency, then your body will be signaled to create more testosterone.
