Nolvadex (tamoxifen citrate)
20 mg x 30 tabs
Nolvadex is a popular and powerfully effective Selective Estrogen Receptor Modulator (SERM) that is often referred to as an anti-estrogen. However, while being an antagonist it is also an agonist as it will actually act like estrogen in certain parts of the body while acting as an anti-estrogen in other areas.
Nolvadex, officially known as Tamoxifen Citrate, was first developed in 1961 by ICI now AstraZeneca under the trade name Nolvadex. The SERM was developed to treat breast cancer, specifically hormone-responsive breast cancer. However, it has also been effectively used in breast cancer prevention.
