Manufacturer's Description:

Tamoxifei is commonly referred to in quite a few ways: as a SERM (Selective Estrogen Receptor Modulator), as an anti-estrogen (that is actually incorrect, as we will later see), and finally as a triphenylethylene. I happen to stick with calling Nolvadex a SERM, because out of my three options, it happens to be correct (as we know that calling it an anti-estrogen is incorrect), and pronouncable (as we know that I have no idea how to say "triphenylethylene"). Selective estrogen receptor modulators (SERMs) act as either estrogen receptor agonists or antagonists in a tissue-selective manner, lets see what that means to us. 

Nolvadex actually has quite a few applications for the steroid using athlete. First and foremost, its most common use is for the prevention of gynocomastia. Nolvadex does this by actually competing for the receptor site in breast tissue, and binding to it. Thus, we can safely say that the effect of tamoxifen is through estrogen receptor blockade of breast tissue (1), especially since total body estradiol increases with use of tamoxifen. Clearly, if you are on a cycle which includes steroids which convert to estrogen, you may want to consider nolvadex as a good choice to run along side them.
