Under current conditions with noticeably increased competition between the leading sports countries on the global stage, the greatest success is achieved, as a rule, by representatives of the country, in which the latest achievements of science and technology are best used. The level of modern sport development, those overloads that the athletes experience are so high that any attempts to stop using medicinal preparations reflect the views of not even yesterday, but the day before yesterday. Over the past 15-20 years, the volume and intensity of training and competitive loads have increased by 2-3 times, and representatives of many sports events have almost reached the limit of the human body physiological capacities. That having been said, the nutritional inadequacy of athletes' diets, the need for recovery and preventive measures, body adaptation to intensive physical and psychoemotional loads as well as frequent climate and time zone changes necessitate the usage of pharmacological preparations contributing to work capacity increase and accelerating the recovery processes after significant loads. Unfortunately, this has led to widespread usage of doping in general and anabolic steroids, in particular.Anabolic means are the substances the action of which is aimed at intensification of anabolic (synthetic) processes in the body, i.e. substances accelerating formation and regeneration of structural parts of cells, tissues and muscular structures. Non-Olympic sports events representatives and the youth not engaged in professional sport tend to use steroid doping as well. The prevalence of usage of banned substances and methods remains high, reliable highprecision methods for the detection of many of them are absent, and athletes, not knowing the pitfalls of taking anabolic agents, continue to use them on a mass scale, which can cause both immediate and remote negative effects on health and quality of life. Therefore, every new attempt to explain potential health and life quality hazards is a step forward in the fight against doping.This review presents modern classification of anabolic agents, headlines their action mechanism and details side effects of using representatives of all three groups of banned drugs including those recently synthesized. It is emphasized that the use of anabolics may not only lead to deprivation of medals won illegally, but cause immediate and delayed negative influences on the athlete's body further resulting in deterioration of social adaptation, loss of health and, possibly, life itself.
