Professionally tested drug-free bodybuilding events for over 20 years.
USBF is a drug-tested organization and urinalysis is the testing method. The USBF has adopted the IOC’s Anabolic Steroid Banned Substance List that includes related substances such as Andro (converts to testosterone) and 19-Nor (converts to Nandrolone). The fact that a substance is sold over-the-counter does not automatically make it acceptable for drug tested competition. Ephedrine is formally banned by the USBF.
As a competitor that chooses to compete in drug-tested competition, you are responsible for being knowledgeable about the supplements that you consume.
