And tell them to stay away from the other performance-enhancing drugs that are already on the NFL’s list of banned substances. The league and the players union have agreed to increase the fines for being caught for using performance-enhancing drugs and have added EPO (Erythropoietin) to the list of banned enhancers [NFL, players agree to more extensive drug testing]. Also, from now on 10 players will be randomly tested each week (formerly it was 7 players).
If your clients are still taking HGH, steroids, or any other performance enhancer, you may want to suggest that this be the time to stop. The NFL is starting to get serious, and so are other professional leagues. Better to be safe than sorry.
