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 as estrogen in certain parts of the body while acting as an anti-estrogen in other areas. As one of the oldest SERM’s on the market that is still regularly used medicinally, while Nolvadex is also used by anabolic steroid users it is not an anabolic steroid. This is an important note as some are often confused by its use in steroid cycles. Nolvadex is simply a SERM. 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. Then we have anabolic steroid users, and it was long ago discovered that Nolvadex had a place among such individuals. Nolva, as it’s commonly known, can be used as an anti-estrogen during an anabolic steroid cycle in order to prevent estrogenic related side effects. It is also used as part of a Post Cycle Therapy (PCT) recovery plan, which is its most common and beneficial point of use for the steroid user.
Nolvadex Functions & Traits:
Tamoxifen Citrate is a SERM with both estrogen agonist and antagonist properties. As an anti-estrogen, Nolvadex functions by binding to the estrogen receptors in the place of estrogen. This binding prevents the estrogen hormone from performing its action in certain parts of the body, which is precisely why it’s beneficial to breast cancer patients. Many forms of breast cancer actually feed off estrogen when it attaches to the receptors in the chest. By preventing the attachment in such receptors, this also protects anabolic steroid users from gynecomastia, which can be caused by anabolic steroids that aromatize such as Testosterone, Dianabol, and Nandrolone and Boldenone to a degree. While primarily viewed as an anti-estrogen, Nolvadex also has the ability to act as estrogen, specifically in the liver. This presents a benefit as estrogenic activity in the liver has been linked to healthier cholesterol levels. For the steroid user, this can be extremely beneficial as many anabolic steroids tend to have an adverse effect on cholesterol. More on this when we look at the direct effects of Nolvadex later on. Although primarily an anti-estrogen, Nolvadex also possess strong testosterone stimulating characteristics. Nolvadex has the ability to block the negative feedback that is brought on by estrogen at the hypothalamus and pituitary. As a result, this stimulates an enhanced release by the pituitary of Luteinizing Hormone (LH) and Follicle Stimulating Hormone (FSH). Both LH and FSH are essential to natural testosterone production. Without LH and FSH, with an even stronger emphasis on LH, there is no natural testosterone production.
