This article presents the prevalence of stimulant doping among Brazilian athletes, the analytical approaches used, as well as a general evolution of the detectability of the stimulants being used. Results from the Brazilian accredited doping control laboratory are compared with the global statistics disclosed by the World Anti-Doping Agency. The high prevalence of stimulant doping in Brazil can be attributed to several reasons, including "self-administration," a "body-shaping" culture, and the use of nutritional supplements.
