I THOUGHT I WOULD POST THIS FOR ANYBODY WHO'S INTRESTED IN LEARNING SOMETHING THEY MAY NOT KNOW
Nandrolone (AKA 19-Nor-Testosterone or 19-Nor-Androstenolone) is an Anabolic Steroid. As the names suggests, it is related to Testosterone, a "male" hormone produced naturally in humans (male AND female) in varying quantities. All Anabolic steroids have "Androgenic" effects, which are the actions we commonly associate with Testosterone; masculinisation, aggression, virilisation, growth, but only up to a point, and with (serious!) reservations. Anabolic steroids also have "Anabolic" effects, those associated with growth of bone, muscle, red blood cells and mobilization of sugar. These are more the effects sought by athletes abusing this range off drugs. Although some Testosterone type anabolics are orally active, they undergo a very heavy Liver process, removing a lot of their action, and also stressing the liver. Serious abusers, or legitimate patients tend to have injections, or to take safer more orally compatible anabolics like Stanazolol (the drug found twice in Ben Johnston's blood)
Anabolic steroids when used legitimately are used most often to stimulate some sort of growth, so are used in advanced osteoporosis, certain breast cancers, regeneration of red blood cells in kidney patients, puberty disorders, growth disorders, anemia, and to help gonad development (in males). Illegitimate use is focused on increasing muscle mass and strength, but will also increase red blood cell production, therefore blood thickness and oxygen-carrying capacity.
Nandrolone is produced in both males and females as a metabolite (by-product) of Testosterone, and studies have shown it can be elevated to a very detectable level. The studies however did NOT prove the elevated levels would exceed the IOC threshold for a positive test.They barely reached a quarter of this value
In defence athletes often ask why would anyone take Nandrolone when there are better illegal substances for middle-distance or endurance athletes? This is indeed debatable, and MAY suggest the taking has been more inadvertent, but maybe this last possibility is the exact reason they take it. They can suggest a defence saying it must have been in one of the supplements. Nandrolone helps muscle grow, and muscle stores glycogen, so no matter what the sport, if taken with the right type of training, it will improve endurance, strength and oxygen-carrying capacity.
