Changes in the endogenous profile of androgenic anabolic steroids (AAS) may be interpreted as markers of doping. The objective of this study was to evaluate the endogenous profile of AAS in male athletes of the 2009 Brazilian National Soccer Championship, in normal conditions, particularly in the light of the revision of World Anti‐Doping Agency's (WADA) Technical Document on the Interpretation of Endogenous AAS in athletes for doping control drafted in that year, as well as comparing these results to profiles already published in the literature. The upper limit of the 95% central reference interval of the following parameters for the studied population were estimated to be significantly higher than WADA's criteria, with a confidence of 90%: DHEA (about 2.3 times higher), Adiol (1.2 times higher), Bdiol (2.7 times higher), and Adiol/E (6 times higher). These findings seem to imply that WADA's criteria proposed in 2009 for DHEA, Adiol, Bdiol, and Adiol/E may not have been applicable to the studied population. Moreover, their comparison to previously published studies pointed to the need to evaluate in detail the appropriateness of adopting these criteria as universal, since there seems to be variations among different populations of athletes.
