Some tests used by the WADA are not trustworthy

Players of the NFL distrust methods applied by the WADA. Why did the mistrust appear? Let try to understand the reason.
The World Anti-Doping Agency (WADA) made a decision to test players of the National Football League for HGH. However the NFL Players’ Association has agreed, certain skeptic words linked with the grade of trustworthiness of blood test for HGH were expressed. This test is going to be just a part of the testing for anabolic steroids and other performance-enhancing substances.
Several experts that are not involved in the WADA activity directly don’t agree with the methods applied by this agency. They justify the skepticism of the NFL players.
Matt Chaney, a main chronicler of intake of steroids in American football, confirms that players of the NFL mistrust the WADA anti-doping tests not without any reason. Skepticism of the players is justified by Matt Chaney.
Don Catlin, the director of Anti-Doping Research, says that methods of the WADA for detection of HGH should be transparent. The WADA applies the HGH isoform ratio test elaborated by Christian Strasburger.
It is necessary to note that according to some specialists, the HGH isoform ratio test is not proved scientifically. It is not trustworthy. Catlin claims that this test is not good for detection of HGH at all.
There is another test which may be used by the WADA to determine sportspersons that utilize HGH. Sonksen introduced a certain HGH testing method which is based on physiological biomarkers. But the WADA doesn’t applies this method to determine consumers of HGH.
According to Sonksen, workers of the WADA are not specialists in this area. That’s why they do not see the priority of one method over the other. But as it was proved by scientists, the HGH biomarker test is more useful than HGH isoform test.
Although experts confirm about difference between these two tests, the WADA doesn’t intend to change the method.
