Save your money! The androgens they sell as dietary supplements (like DHEA) don't get readily turned into testosterone unless you have a testosterone deficiency. In medicine you can't say that all males over 50 will have a deficiency, but go to your physician and have your blood level of testosterone measured. If there's a deficiency, he can give you an injection of testosterone, the prescription kind, which actually cost less than a dollar. There are also other forms, like oral or skin-patches.
This way you'll be getting the real thing (testosterone) at the real dosage without having to guess how much DHEA it will take to MAYBE increase those levels.
When I said (anabolic) steroids (like androgens) are federally controlled, that means that not only are they restircted to "by prescription," but that possessing them without a prescription (at certain strengths) can be a violation of the federal drug laws, just like possessing heroin. So don't let some jerk at the gym sell you an anabolic steroid, especially in injectable form.
As for the FDA/MD thing, the US FDA is enjoined by law from interfering with the practice of medicine. It can only regulate the manufacture of pharmaceuticals (and some other things, like medical devices), but it cannot tell physicians how to practice medicine. And there's lots of stuff that is "prescription only" that does NOT work.
People should be sensitive to their bodies, but, believe me, what's out there is vey complex and not many people can manage all the information on what's good and/or bad. People should seek help from informed sources.
