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.
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).
The Marker degradation is a three-step synthetic route in steroid chemistry developed by American chemist Russell Earl Marker in 1938–1940. It is used for the production of cortisone and mammalian sex hormones (progesterone, estradiol, etc.) from plant steroids, and established Mexico as a world center for steroid production in the years immediately after World War II.

19-Norandrosterone, also known as 5α-estran-3α-ol-17-one, is a metabolite of nandrolone (19-nortestosterone) and bolandione (19-norandrostenedione) that is formed by 5α-reductase.
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 ...
A commonly consumed example of said precursors are androstenedione and androstenediol, both of which are currently banned substances in the United States. [6] [7] However, several illegal steroids, such as 1-testosterone, are still being produced legally under different chemical names, and the majority have not undergone clinical studies. [6] [8]
