yes tamoxifen is nolvadex. They are the same.
I doubt you need nolv if you have an anti aromatase. go with aromasin, liquidex, or femara and you will likely not need any tamoxifen. It wouldn't hurt having some on hand but I doubt you'll need it. I run test @ 2g/wk along with50mg dbol/ ED and one femara ED keeps all estrogen away...
