Why would you need to use a Estrogen Blocker? Some people carry higher estrogen levels in their bodies. Guys can notice it in areas like nipples and pecs. Estrogen can also come from using prohormones or other sports supplements.
How to use a Estrogen blocker
If you are using a estrogen blocker to lower natural estrogen levels simply follow the instructions on the bottle. If you are using this type of product to remove estrogen from a cycle keep this in mind. First if you are using a wet compound consider starting an estrogen supplement before your cycle. Then continue use through the entire cycle and for a week once the cycle is done. This will help protect you from increasing estrogen levels during a cycle.
