Nolvadex was the brand under which tamoxifen citrate first reached the market, and the word has outlived the patent to become shorthand for the molecule itself — which is why Dragon Pharma still prints it on the carton.
Inside the carton are one hundred tablets of 20 mg. What they contain is an oral SERM rather than an androgen, whatever shelf it happens to be filed on: it blocks the estrogen receptor in breast tissue instead of adding any hormone at all.
Dragon Pharma presses its logo into the face of the tablet and runs a code verification system on the cartons.
