Nandrolone, also known as 19-nortestosterone, is an endogenous androgen. It is also an anabolic steroid (AAS) which is medically used in the form of esters such as nandrolone decanoate (brand name Deca-Durabolin) and nandrolone phenylpropionate (brand name Durabolin).[2][12][8][13] Nandrolone esters are used in the treatment of anemias, cachexia (muscle wasting syndrome), osteoporosis, breast cancer, and for other indications.[8] They are now used by oral administration or instead are given by injection into muscle or fat.[8][13][14]

Side effects of nandrolone esters include symptoms of masculinization like acne, increased hair growth, and voice changes.[8] They are synthetic androgens and anabolic steroids and hence are agonists of the androgen receptor (AR), the biological target of androgens like testosterone and dihydrotestosterone (DHT).[8][15] Nandrolone has strong anabolic effects and weak androgenic effects, which give them a mild side effect profile and make them especially suitable for use in women and children.[8][15][16] There are metabolites of Nandrolone that act as long-lasting prodrugs in the body,[8] such as 5α-Dihydronandrolone.

Nandrolone esters were first described and introduced for medical use in the late 1950s.[8] They are among the most widely used anabolic steroid worldwide.[8] In addition to their medical use, nandrolone esters are used to improve physique and performance, and are said to be the most widely used anabolic steroid for such purposes.[8][17] The drugs are controlled substances in many countries and so non-medical use is generally illicit.[8]
