The other day I was listening to Dr. Dean Edell (sounds like Dena Dell), who was advising a caller about testosterone patches. The doctor said, that testosterone varies widely and in the case of replacement therapy, you must monitor it carefully. It can go up or down for many reasons. When the story about Landis and his high testosterone came out that segment was the first thing that came to mind.
Of course Landis could have just held a gun.
