NFL Suspends 6 Players for Doping Violations

"You and you alone are responsible for what goes into your body. Claiming that you used only legally available nutritional supplements will not help you in an appeal. ... Even if they are bought over-the-counter from a known establishment, there is currently no way to be sure that they contain the ingredients listed on the packaging or have not been tainted with prohibited substances ...

"If you take these products, you do so AT YOUR OWN RISK! For your own health and success in the league, we strongly encourage you to avoid the use of supplements altogether, or at the very least to be extremely careful about what you choose to take."

The NFL also said it sent two notifications about StarCaps on Dec. 19, 2006 — one to NFL club presidents, general managers and head athletic trainers and the second to NFLPA executive Stacy Robinson, who oversees the steroid policy for the union. That letter, according to the league, advised that StarCaps had been added to the list of prohibited dietary supplement companies.

Asked if the NFL would review its policy on diuretics, Birch said the policy is reviewed every year.

"I suspect the players' association may want to look specifically at diuretics or some other issues. We'd be happy to do that with them if appropriate," he said. "I do think it's good policy. It works well. It has different aspects to it, but we will certainly listen with an open mind and if it's appropriate to make change, make changes."
