Tamoxifen (Nolvadex) 20mg Tablet
Nolvadex is an oral anti-estrogen/estrogen antagonist prescription drug. Nolvadex is commonly referred to as an anti-estrogen, but technically it is more of an estrogen antagonist. An estrogen antagonist has a unique way of preventing estrogen activity. What it does is to compete with estrogen at the receptor sites, occupying it so that estrogen cannot bind with it.
