Nandrolone undecylenate

 Nandrolone is an anabolic steroid. Nandrolone is most commonly sold commercially as its decanoate ester (Deca-Durabolin, eubolin, retabolil) and less commonly as a phenylpropionate ester (Durabolin, fenobolin). Nandrolone decanoate is used in the treatment of osteoporosis in postmenopausal women (though now not recommended) at a dose of 50 mg every three weeks. It is also used for some aplastic anemias.
