What is Nolvadex?

Nolvadex (tamoxifen citrate) is a medication used to treat and prevent breast cancer. It is a non-steroidal anti-estrogen that competitively inhibits estrogen receptors in the target organs and tumors in them. Nolvadex is commonly used in the bodybuilding community for its off-label use as a performance-enhancing drug.

Mechanism of Action

Nolvadex (tamoxifen citrate) is a selective estrogen receptor modulator (SERM) that binds to estrogen receptors in breast tissue and other organs. It acts as an antagonist, blocking the effects of estrogen on these receptors. This can inhibit the growth of estrogen-dependent breast tumors; Additionally, Nolvadex can stimulate the production of luteinizing hormone (LH), which can lead to ovulation in women of reproductive age. This effect can be beneficial for women who are trying to conceive after breast cancer treatment.

Nolvadex is also known to have anti-inflammatory and antioxidant properties. It can inhibit the production of pro-inflammatory cytokines and reduce oxidative stress, which may contribute to its protective effects against breast cancer.
