Before reading other sections, it is essential that the reader had a basic idea of what steroids are and the natural production of testosterone and its effects. This is probably boring for many readers, but steroids action is essential basic knowledge. Besides the obvious fact, it is a kind of fun that allows you to find out what else “boys” can do. Some readers should be warned against the style of writing: so some may feel embarrassed by openness regarding any subject including sexuality. The authors have no intention of apologizing to anyone who chose to read this book. To be honest, it is our right to freedom of speech and the reader to choose not to read or disagree. There are several sex hormones. Some such as estradiol, estrone and progesterone are sex hormones belonging to the estrogen group. Androstenedione, androstenediol and testosterone are called naturally occurring endogenous (produced in the body) androgens. The previous group are the leading female hormones responsible for the formation of sexual characteristics associated with the deposition of fat in places typical for women such as breasts, thighs, buttocks, as well as for the formation and formation of female genital organs. The second group, androgens, are the leading male hormones that are responsible for features such as lower voice, greater bone and muscle mass, facial hair, increased body hair, formation and development of male sexual organs and aggression.

Both men and women produce androgens and estrogens. The dominant feature in women is the production of estrogens, and in men – androgens. If it were to change, each of the sexes would, to some extent, take on the characteristics of the other. Our main goal of other sections is male androgen, testosterone, and almost all its endless derivatives and esters. On average, a man produces 4 – 10 mg of testosterone daily. This means that the average man can synthesize 28-70 mg of endogenous testosterone per week. However, before we continue, we also need basic knowledge about other hormones.

Specifically

Anabolic steroids of natural or synthetic origin are a group of steroids, which has a strong anabolic effect, i.e. steroids, accelerate the sharing of cells that create specific tissues of animals and humans. The action of some anabolic steroids is to stimulate the growth of muscle mass and sometimes also bones. This effect is particularly important in sports doping. Anabolic steroids also have many side effects, because they strongly affect the overall hormonal balance of the body. One of the best-known natural anabolic steroids is testosterone, which also acts as a male sex hormone. Anabolic steroids work by activating androgen receptors on the surface of cell membranes. The effects of this stimulation are usually divided into generally anabolic and related to the formation of sex differences. Examples of anabolic effects:  increased protein synthesis,  increase in the rate of mass gain, strength and endurance,  increase in appetite, increase in bone growth rate, increased production of red blood cells. Examples of the effect of sexual differentiation: increase in the size of the penis and clitoris in children (in adults, administration of any steroids has no effect on the size of the genitals), increase in chest size in boys, breasts and hips in girls, increased body hair growth in men and erogenous spheres in women, effects of voice mutation in boys. Although chemists aim to obtain steroids that would only cause anabolic effects and do not interfere with the effects of sexual differentiation, nowadays practically all synthetic anabolic steroids cause both effects. This is due to the fact that all of them are metabolized by the human body, and the products of their metabolism have a side effect by activating estrogen receptors, which causes various undesirable effects, such as: accelerated aging of some tissues (especially bones in men), unnatural growth breasts in both women and men (gynecomastia), imbalance of sex hormones causing an unnatural decline in sex drive in men and its artificial growth in women.

Anabolic steroids began to be used in medicine in the 1940s with variable luck

Many attempts to use them often led to side effects, which were worse than the disease itself, which means that their use is practically abandoned, with the exception of one testosterone use, in some strictly limited cases. Among others they were used to: stimulate bone growth in hypoplastic anemia – but now they are replaced with natural protein hormones, obtained by biotechnology, which have much better anabolic selectivity, regulating the growth rate in children who show abnormal growth (grow too slow or too fast) ) – natural protein hormones that do not have such drastic side effects as synthetic anabolics are now also used for this purpose  stimulating the increase in appetite and body weight in some diseases that cause lack of hunger – this is a way to treat people suffering from AIDS – but with a fairly mediocre effect accelerating the sexual development of boys, in whom it starts far too late – the treatment of this developmental disorder is carried out by administering controlled doses of testosterone – currently it is actually the only medical therapy carried out with the use of rudder anabolic Jews. Applications and abuses in sports doping. Anabolic steroids are often used by athletes as a form of illegal chemical doping. Initially, especially in the 1970s and 1980s, their use was not officially prohibited, as these steroids were just beginning to appear on the market, and their appearance was faster than changes in sporting law. Anabolic steroids are especially often used in the so-called strength sports, in which strength and endurance of the muscles determine the success.

This is especially true for bodybuilding, weightlifting, many drug competition (running, long jump etc.), swimming competition and cycling. In the mid-1990s, the authorities of the International Olympic Committee have completely banned the use of anabolic steroids in official sport, which entailed similar prohibitions in most countries of the world that send athletes to the Olympics. Modern methods to detect the use of anabolic steroids (eg gas chromatography of extract from pubic hair) allow detection of their consumption even after 2-3 years from this fact. Nevertheless, there are reasonable suspicions that the underground industry of production and research on anabolics is still quite active. Between the anti-doping laboratories and the doping industry, the type of game is still going on. The newly obtained chemicals having an anabolic effect are introduced into the black market before the anti-doping laboratories will learn to detect them. The use of anabolic steroids by people practicing sports purely for recreation is still not allowed in most countries, including Poland. However, their amateur use during adolescence often results in the inability to continue a professional sports career in adulthood.
