The NFL Players Association is stalling big time from allowing the NFL to test them. I always thought you had to take HGH daily or else it is out of your system. Isn't the only way a test will find HGH in your system is if you just took or is there some residual HGH level that remains high for weeks afterwards like testosterone does?
Sort of like testing someone for Drinking. You can only tell if they had a drink at that moment, not a week later.
