Drug Testing in Athletes

In a study designed to assess possible interference with tests to detect performance-enhancement drugs (doping), 20 male and 20 female athletes were asked to take 200 mg of COLD-fX 2 times daily for 28 days.42 Compliance was assessed at 98% by counting returned pills. Urine samples were collected and assessed by an International Olympic Committee certified laboratory. No banned substances (positive doping tests) were detected in any of the samples.
