General information on steroids.
Today, almost everyone at the word "steroids" immediately thinks of anabolic steroids, known to amateurs as "anabolics". However, it is often forgotten that "steroids" is the general name for a whole group of various steroid hormones. Among them - hormones of the adrenal cortex (gluco- and mineralocorticoids), female sex hormones (estrogens and gestagens), as well as male sex hormones (androgens). This book will focus exclusively on the latter - androgens. With their most important representative, testosterone, the reader has already met in the previous chapter. Therefore, henceforth, with the word "steroids" we will mean anabolic - androgenic steroids.
Anabolic - androgenic steroids are synthetic obtained formations, similar in some of their qualities to the natural male hormone androgen - testosterone. The main reason for their development was the intention to create a drug that would have high anabolic qualities of testosterone, but at the same time would exclude its strong androgenic capabilities. "Enormous efforts have been made to create a pure anabolic drug without admixture of androgenic" side effects "(Kahakiyan, 1976; Kruskemper, 1965)." (Quote from "Doping - Prohibited Drugs in Sports", p. 51, Dirk Klasing, Manfred Donica et al.). To realize this idea, huge changes were made to the steroid molecule. Newly created steroids differ at that time either by an underestimated anabolic androgenic function, or have increased efficacy in both qualities. Some steroids have received such structural changes that have led to even higher androgenicity and decreased anabolic activity. This explains the differences in action, effectiveness, side effects of existing steroids. The creation of a pure anabolic, where the anabolic and androgenic qualities of the steroid would be completely separated, failed. Therefore, the so-called anabolic steroid (anabolic) has some degree of androgenic effects, and vice versa, androgenic steroid
