The NFL could be taking HGH testing to another level.

The league and the players’ union plan to give dozens of former players human growth hormone and incorporate their subsequent HGH levels into a study, according to a USA Today Sports report yesterday.

Citing three sources with knowledge of the plan, USA Today Sports reports the tentative study would include about 100 former players. Two-thirds would be given HGH, and the rest would get a placebo.

All of the former players’ HGH levels would be tested before and after. It is unknown if any former players have agreed to take part.

According to the report, the ultimate goal of the testing is to determine a “decision limit,” or the highest HGH level a player can register before reaching the threshold for discipline under the yet-to-be finalized performance-enhancing drug policy.

In the collective bargaining agreement reached two years ago, the NFL and players’ union agreed to blood testing for HGH.
