Some specialists support skepticism of NFL players to the WADA anti-doping tests

Players of the NFL do not trust methods used by the WADA. Why did the distrust appear? Let try to understand the reason.
The World Anti-Doping Agency (WADA) decided to test players of the National Football League for HGH. However the NFL Players’ Association has agreed, certain skeptic thoughts connected with the level of trustworthiness of blood test for HGH were expressed. This test is going to be only a part of the testing for anabolic steroids and other performance-enhancing substances.
Several experts who are not connected with the WADA activity directly don’t agree with the methods applied by this agency. They support the skepticism of the NFL players.
Matt Chaney, a main chronicler of steroids use in American football, confirms that the NFL players do not trust the WADA anti-doping tests not without any reason. Skeptic attitude 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 uses the HGH isoform ratio test elaborated by Christian Strasburger.
It is necessary to mention that according to some specialists, the method of this test doesn’t have scientific basis. It is not trustworthy. Catlin confirms that this test is not good for detection of HGH at all.
There is another test that can be used by the WADA to determine sportsmen that administrate HGH. Sonksen introduced a certain HGH testing method that is based on physiological biomarkers. But the WADA doesn’t use the method of Sonksen to determine users of HGH.
According to Sonksen, employees of the WADA are not specialists in this area. That’s why they do not understand the priority of one method over the other. But as it was proved by specialists, the HGH biomarker test is more useful than HGH isoform test.
Although experts point out about difference between these two tests, the WADA doesn’t want to to utilize the HGH biomarker test.
