Nandrolone undecanoate (brand names Dynabolon) is an anabolic androgenic steroid (AAS), which had been used for the treatment of the anemia of chronic renal failure for more than 25 years. Due to concerns over adverse effects, their use historically has been limited to nandrolone decanoate given to men, usually over age 50, who have intact kidneys. It binds to the androgen receptor to a greater degree than testosterone, but due to its inability to act on the muscle in ways unmediated by the receptor, has a less overall effect on muscle growth. Despite the fact that AAS are banned substances by professional sports organizations and illegal drugs by the DEA, they are used and abused extensively, especially by teenagers and young athletes or non-athletes either for cosmetic or recreational purposes. Users may even take from 10 to 100 times higher doses than the physiological one.

Nandrolone, also known as 19-nortestosterone or 19-norandrostenolone, is a semisynthetic anabolic-androgenic steroid derived from testosterone. Nandrolone is used in the form of a variety of long-acting prodrug esters for intramuscular injection, the most common of which are nandrolone decanoate. Nandrolone decanoate is indicated for the management of the anemia of renal insufficiency and has been shown to increase hemoglobin and red cell mass. Certain clinical effects and adverse reactions demonstrate the androgenic properties of this class of drugs. Complete dissociation of anabolic and androgenic effects has not been achieved. The actions of anabolic steroids are therefore similar to those of male sex hormones with the possibility of causing serious disturbances of growth and sexual development if given to young children. Anabolic steroids suppress the gonadotropic functions of the pituitary and may exert a direct effect upon the testis. Anabolic steroids have been reported to increase low-density lipoproteins and decrease high-density lipoproteins. Synthetic version of nandrolone was developed in 1950. But nandrolone for sale appeared later only in 1962 in the form of decanoate under the trade name Deca-Durabolin (Organon company).
