As a result of studying 43 endogenous steroids, we obtained their full mass spectra, retention times and characteristic ions. When constructing the calibration dependencies, we compared several matrices and showed their advantages and disadvantages. The developed technique was used for more than three years for the real samples analysis. On the base of the obtained data, for the first time we set reference limits for Russian athletes, and a form of the data is consistent with the literature, and the maximal concentration values set for the male and female population of Russian athletes vary...
