In the current culture of sports, performance-enhancing drugs are a part of the everyday conversation. This is something the NFL is trying to curtail now, with the news that it wants HGH testing for the 2013 season after submitting a proposal in late April, according to NFL.com.
Other substances are already banned by the NFL, including different types of steroids that carry an automatic four-game suspension. However, HGH isn't on the list.
The problem is that it's hard to figure who is guilty of taking HGH because there isn't a baseline established. It's unclear what levels an adult man should have in his body and just how HGH affects a human, something the World Anti-Doping Agency is working on.
In the meantime, the NFL wants to take blood and urine samples from the players and store them until a baseline is created. The NFL Players Association would rather the baseline be set before samples are taken, thus causing the stalemate.
