"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***8217;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. In the late 1990s, a number of brilliant anti]doping scientists.some of whom later acted as consultants to VADA.collaborated to develop a better way to detect doping with testosterone by using isotope ratio mass spectrometry (IRMS). The CIR/IRMS method is considered a superior, highly reliable test that culminates in measuring isotope ratios to determine whether testosterone is produced naturally or artificially.
