Nandrolone, also known as 19-nortestosterone, is an anabolic androgenic steroid that occurs naturally in the human body, albeit in tiny quantities. The structure of the molecule is very similar to the male hormone testosterone, and it has many of the same effects in terms of increasing muscle mass and reducing the fatigue associated with training, and reducing the time required for recovery after physical exertion. Nandrolone, (usually in the form of injectable Deca Durabolin) is one of the most commonly abused anabolic androgenic compounds in the world. Since it is not metabolised to dihydrotestosterone Nandrolone has somewhat milder unwanted side effects than testosterone. It was previously used clinically for treatment of osteoporosis in post menopausal women at a dose of 50 mg every three weeks. However, as the abused doses are normally 10-100 times the therapeutic dose, side effects such as breast enlargement, acne, erectile dysfunction occurs in men and increased body hair, alteration of the voice, reduction of the breasts etc. in women. In addition, long term use leads to cardiovascular and liver damage. Nandrolone is metabolised to 19-norandrosterone, the substance detected in doping tests. Since it occurs naturally in the body there is a detection cut off concentration of 2 ng/ml and concentrations above that are considered suspicious. In 2007 the five-time track and field gold medalist Marion Jones admitted to use of the drug, and was sentenced to six months in jail for lying to a federal grand jury in 2000. http://en.wikipedia.org/wiki/Nandrolone http://www.chm.bris.ac.uk/motm/nandrolone/nandc.htm This substance (including esters such as decanoate and phenylpropionate) was added to the doping list ahead of the Montreal 1976 Olympic Games.
