Unlike prescription and over-the-counter medications, you can’t check supplements on Global DRO. Supplements are regulated differently than medications and always come with some level of risk for athletes. Visit Supplement Connect for more info.

This Clean Sport Handbook is designed to provide athletes and athlete support personnel with a summary of the information needed to successfully participate in the anti-doping program governing their sport. 

USADA is unwavering in its belief that every athlete has the right to compete on a clean and level playing field, free from the pressures and influences of performance-enhancing drugs. For this reason, USADA makes available a number of ways to report the abuse of performance-enhancing drugs in sport in an effort to protect clean athletes and promote clean competition.

Athletes are subject to testing 365 days a year and do not have “off-seasons” or cutoff periods in which testing does not occur. Whereabouts information (dates, times, locations, etc.) is information submitted to USADA by an athlete that allows the athlete to be located for out-of-competition testing.
