Nolvadex (Tamoxifen) is a selective estrogen receptor modulator (SERM) commonly used in bodybuilding to prevent or treat estrogen-related side effects like gynecomastia.
It works by blocking estrogen receptors in certain tissues, such as the breast, while acting like estrogen in others.
Often used during post-cycle therapy (PCT), Nolvadex helps restore natural testosterone production after steroid use and promotes hormonal balance.
It is also effective in reducing water retention and other estrogenic side effects.
