VADA calls for synthetic testosterone test

Dr. Margaret Goodman and the Voluntary Anti‐Doping Association (VADA) have called for professional sports leagues to immediately adopt the Carbon Isotope Ratio (CIR) test for every screen used in testing for performance‐enhancing drugs. To date, only fighters who participate in VADA’s rigorous voluntary program undergo such testing. “The recent positive tests for synthetic, or artificial, testosterone in professional and elite sports demonstrate that it is a problem at the highest levels of sport,” said Dr. Goodman, President of VADA. “Clearly, some athletes are choosing to use the substance because they know it is not tested for upfront. It’s long past time that the CIR test was used across the board to test for synthetic testosterone.”

In nearly all sports today, the CIR test is only used when testers suspect from other indicators a presence of synthetic testosterone. As a result, athletes and trainers who understand the limitations of this testing can “microdose” with synthetic testosterone in order to avoid triggering a CIR test, which can determine whether testosterone is produced naturally or artificially.
