Nandrolone decanoate

Résumé
Nandrolone decanoate, sold under the brand name ROLON among others, is an androgen and anabolic steroid (AAS) medication which is used primarily in the treatment of anemias and wasting syndromes, as well as osteoporosis in menopausal women. It is given by injection into muscle or fat once every one to four weeks. Side effects of nandrolone decanoate may include symptoms of masculinization like acne, increased hair growth, voice changes, and decreased sexual desire due to its ability to suppress endogenous testosterone synthesis while not being a sufficient androgen itself. The medication is a synthetic androgen and anabolic steroid and hence is an agonist of the androgen receptor (AR), the biological target of androgens like testosterone and dihydrotestosterone (DHT). It has strong anabolic effects and weak androgenic effects, which give it a mild side effect profile and make it especially suitable for use in women and children. Nandrolone decanoate is a nandrolone ester and a long-lasting prodrug of nandrolone in the body. Nandrolone decanoate was first described in 1960 and was introduced for medical use in 1962. It was the second nandrolone ester to be introduced, following nandrolone phenylpropionate (NPP) in 1959, and is one of the most widely used nandrolone esters. It is also one of the most widely used AAS worldwide. In addition to its medical use, nandrolone decanoate is used to improve physique and performance, and is said to be the most widely used AAS for such purposes. The drug is a controlled substance in many countries and so non-medical use is generally illicit. Anabolic steroid#Medical Nandrolone decanoate is approved in the United States specifically for the treatment of anemia of chronic kidney disease and in the United Kingdom specifically for the treatment of osteoporosis in postmenopausal women. In Australia, it is approved specifically for the treatment of kidney failure, chronic kidney disease, anemia of kidney failure, aplastic anemia, osteoporosis (in women in whom estrogens are contraindicated), inoperable breast cancer, and for patients on long-term corticosteroid therapy.
