Data of investigation of the presence or absence of anabolic steroids in food supplements used in sports practice

It concerns current important problem regarding presence of undeclared ingredients in FS, which compromises their safety. The professional athletes are not sufficiently aware of the health risks of using some FS, in particular testosterone stimulants, despite their awareness of anti-doping programs and prevention. The study presents chromatographic analyses that confirmed the hypothesis for possible presence of undeclared steroid ingredients in food supplements, formulated by the authors and enabled the following conclusions: More than half of the tested food supplements contained undeclared anabolic steroids, all banned by WADA, as their quantity in one of the samples could be more than one (sample 16 contained 9 steroid substances). The authors also revealed that the information on the product label and package concealed the undeclared ingredients of the food supplement and claimed for high efficacy and safety.
