WAR ON TESTOSTERONE: F.D.A. Panel Backs Limits on Testosterone Drugs. “An expert panel voted overwhelmingly on Wednesday for the Food and Drug Administration to impose strict new limitations on the multibillion-dollar testosterone drug industry, recommending that the agency tighten labels for the medicines so they are not prescribed to men who only have problems related to aging, such as low energy and libido. The F.D.A. often takes the advice of such panels.” I’m leery of this stuff, but I have a friend who went on testosterone therapy 12 years ago and who says it changed his life.
