USADA announced today that Brad Didier, of Huntsville, Texas, an athlete in the sport of triathlon, has accepted a public warning after receiving an intravenous infusion greater than 100 mL per 12-hour period on June 28, 2025.
Intravenous infusions and/or injections greater than 100 mL per 12-hour period are classified as Specified Methods and are prohibited at all times under the USADA Protocol for Olympic and Paralympic Movement Testing, the United States Olympic and Paralympic Committee National Anti-Doping Policies, and the World Triathlon Anti-Doping Rules, all of which have adopted the World Anti-Doping Code and the World Anti-Doping Agency Prohibited List.
After receiving information from a whistleblower, USADA initiated an investigation that demonstrated Didier, 52, received a saline and vitamin infusion the day before participating in a USA Triathlon sanctioned event. USADA’s investigation revealed that Didier was prompted to try the IV after speaking with representatives from an IV clinic advertising their services at the pre-race athlete expo, which athletes were required to attend to pick up their race materials. Encountering the IV clinic in this setting gave the appearance of propriety because Didier had never received formal anti-doping education.
Although no prohibited substances were administered to Didier, the IV constituted a violation because it was over the permitted volume threshold and was not received during a hospital treatment, surgical procedure, or clinical diagnostic investigation. Didier qualified for a reduced sanction based on the circumstances of his case.
Didier has been disqualified from all competitive results obtained June 28–29, 2025, including forfeiture of any medals, points and prizes.
In an effort to aid athletes, as well as support team members such as parents, coaches, and medical professionals in understanding the rules applicable to them, USADA provides comprehensive instruction on its website on the testing process and prohibited substances, how to file and update athlete Whereabouts, how to obtain permission to use a necessary medication, and the risks and dangers of taking supplements, as well as performance-enhancing and recreational drugs.
In addition, USADA manages a drug reference hotline, Global Drug Reference Online (GlobalDRO.com), conducts educational sessions with National Governing Bodies and their athletes, and distributes a multitude of educational materials, such as a supplement guide, a nutrition guide, a clean sport handbook, and periodic alerts and advisories.
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.
