Mestanolone is an oral analogue of dihydrotestosterone. This steroid is a 17-alpha methylated form of this potent endogenous androgen, being essentially (in structure) to dihydrotestosterone what methyltestosterone is to testosterone. Overall, mestanolone has an activity profile not very dissimilar from the hormone it is derived from. Like dihydrotestosterone, mestanolone is primarily androgenic in nature, displaying a low level of anabolic activity. Both dihydrotestosterone and mestanolone are also devoid of estrogenic activity. Dihydrotestosterone was synthesized in 1935. After that 17-alpha-methylated version also appeared. This steroid was not frequently used in clinical medicine. It was produced under the name of ermalon for short period of time. Most studies involving mestanolone were carried out in the 1950s and 1960s. In the 1970s and 1980s it was used as part of the East German doping machine. Mestanolone was evaluated not for its anabolic ability but for its androgenic essence. It improved the functioning of the CNS and neuromuscular interaction. Athletes claimed that it did not make them huge, but gave them speed, strength, aggression, stamina and resistance to stress. Mestanolone is still valued as an oral androgen.

Normethandrone (Orgasteron; Metalutin; Methalutin) is a progestin and androgen/anabolic steroid agent which is used in combination with an estrogen in the treatment of menstruation disorders in women. Normethandrone is a modified form of nandrolone. It differs by the addition of a methyl group at carbon 17-alpha to protect the hormone during oral administration. Normethandrone is aromatized by the body, and converts to a synthetic estrogen with a high level of biological activity (17alpha-methyl-estradiol). Orgasteron has been used as progestational agent and as an androgen. Normethandrone is available in combination with methylestradiol or estradiol valerate in a few countries, including Brazil, Indonesia, and Venezuela. This is a controlled substance (anabolic steroid): 21 CFR, 1308.13, as defined in 1300.01. Normethandrone was first described in 1954. Shortly after, it was developed into a medicine by Organon (now Merck/MSD), which introduced it under the Orgasterone brand name in Belgium and Switzerland, and as Orgasteron in the Netherlands. This steroid had also been sold by other manufacturers in various parts of Europe as Methalutin, Lutenin, and Matdonal. Although a simple oral methylated nandrolone, with strong properties as an anabolic steroid, Normethandrone exhibits such strong progestational activity that it was marketed as an oral progestin. Its anabolic effects were more looked at as secondary applications for the drug, and accounted for very little medical interest.

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).
