Tamoxifen Nolva

An FDA-approved medication for breast cancer treatment and prevention, also widely used off-label by bodybuilders after a steroid cycle to help restore natural testosterone. Extensive research strongly supports its cancer uses, and its hormone-blocking effect reliably explains why it also helps the body's hormone system recover.

Also known as Nolvadex, trans-Tamoxifen, Crisafeno, Tamoxifene, Diemon, Tamoxifeno, Citofen, Istubol
