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.
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]
11-Deoxycorticosterone (DOC), or simply deoxycorticosterone, also known as 21-hydroxyprogesterone, as well as desoxycortone , deoxycortone, and cortexone, [1] [2] is a steroid hormone produced by the adrenal gland that possesses mineralocorticoid activity and acts as a precursor to aldosterone. [3] It is an active (Na+-retaining ...

Dehydroepiandrosterone (DHEA), also known as androstenolone, is an endogenous steroid hormone precursor. [4] It is one of the most abundant circulating steroids in humans. [ 5 ] DHEA is produced in the adrenal glands , [ 6 ] the gonads , and the brain. [ 7 ]
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 .
