One of your athletes gains 10 pounds (4.5 kg) of what looks like mostly lean mass in just over a month; his performance has suddenly shot up, and he seems to have an acne problem that you never noticed before. You overheard him recently telling some other athletes that competitors are using anabolic steroids and getting away with it because of a new product called Maskall, which is guaranteed by the distributor to hide steroid use in a urinalysis. You guess that he is probably the one who recently left the syringe and empty steroid vial in the locker room trash can. You like the improved performance of this athlete. He stands to gain great fame and fortune if he does well in next month’s competition. But you also know that drug testing will be mandatory for the winners. You care about your team and this athlete. What do you do?
