It is on the list of substances prohibited by the World Anti-Doping Agency since it is a detectable metabolite of nandrolone, an anabolic-androgenic steroid (AAS). [1] Consumption of androstendione products contaminated with traces of bolandione may also result in testing positive for nandrolone.
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).
Nornicotine is an alkaloid found in various plants including Nicotiana, the tobacco plant. [1] It is chemically similar to nicotine, but does not contain a methyl group.. It is a precursor to the carcinogen N-nitrosonornicotine that is produced during the curing and processing of tobacco. [2]
These include derivatives e.g. methoxydienone (methoxygonadiene; Ethyl Methoxy Gona), methasterone (so called Superdrol or S-Drol) and many others, sometimes called "designer steroids". Such compounds although harmful, do not infringe the Anabolic Steroid Control Act because they do not have any impact on the testosterone level.

Norsteroids (nor-, L. norma, from "normal" in chemistry, indicating carbon removal) are a structural class of steroids that have had an atom or atoms (typically carbon) removed, biosynthetically or synthetically, from positions of branching off of rings or side chains (e.g., removal of methyl groups), or from within rings of the steroid ring system.

Epitestosterone, or isotestosterone, also known as 17α-testosterone or as androst-4-en-17α-ol-3-one, is an endogenous steroid and an epimer of the androgen sex hormone testosterone. It is a weak competitive antagonist of the androgen receptor (AR) and a potent 5α-reductase inhibitor .
