There is a class of drugs called SARMs which are effectively used in bodybuilding but are not FDA approved. Consider too the numerous psychoactive drugs that have been subjectively reported as benign and beneficial, yet are banned. I have no doubt there are many medicines that have been discovered but never brought to market. Why not is the big question: that data isn't generally available. If I am ever struck by chronic illness, I will not be waiting for the FDA to tell me what does and does not work.
