Oxymetholone, sold under the brand names Anadrol and Anapolon among others, is an androgen and anabolic steroid (AAS) medication which is used primarily in the treatment of anemia. [ 5 ] [ 6 ] It is also used to treat osteoporosis , HIV/AIDS wasting syndrome , and to promote weight gain [ 7 ] and muscle growth in certain situations. [ 5 ]
Metandienone, also known as methandienone or methandrostenolone and sold under the brand name Dianabol (D-Bol) among others, is an androgen and anabolic steroid (AAS) medication which is mostly no longer prescribed. [4] [5] [1] [6] It is also used non-medically for physique- and performance-enhancing purposes. [1] It is often taken by mouth. [1]
Anabolic steroids notably influence muscle fiber characteristics, affecting both the size and type of muscle fibers. This alteration significantly contributes to enhanced muscle strength and endurance. [144] Anabolic-androgenic steroids (AAS) cause these changes by directly impacting the muscle tissue's cellular components.
This is a list of androgens/anabolic steroids (AAS) or testosterone derivatives. Esters are mostly not included in this list; for esters, see here instead. The major classes of testosterone derivatives include the following (as well as combinations thereof):
Oxymetholone (Anadrol-50) Oxandrolone (Anavar) (Note that while the above anabolic steroids remain available in at least one formulation, many of the above-listed brand names have been discontinued.) Ethylestrenol (Maxibolin) and stanozolol (Winstrol) were previously available but were discontinued.
This is a common structure shared by all steroids. [41] The oxygen atom in the lactone bridge replaces a carbon atom at position 2 of the steroid nucleus, classifying oxandrolone as an 2-oxa-steroid. There is a hydroxyl group (-OH) attached at stereo-direction β to carbon 17, which is a characteristic of 17β-hydroxy-steroids. [42]

Nandrolone is the parent compound of a large group of anabolic steroids. Notable examples include the non-17α-alkylated trenbolone and the 17α-alkylated ethylestrenol (ethylnandrol) and metribolone (R-1881), as well as the 17α-alkylated designer steroids norboletone and tetrahydrogestrinone (THG).
