The bottom line is that any supplement, hormone, or treatment should be researched thoroughly to make sure it is safe. There are hundreds of health claims on various supplements and treatments on the web. There are lots of myths. For a more detailed explanation of how things work, see my book, The Myth Busters. You can also view some of the supplements I review here.
My name is Dr. William Regal, and I am a board certified medical doctor. I'm a professor of internal medicine and clinical medicine at the University of Wisconsin School of Medicine and Public Health. I do a lot of research in this area and am a frequent contributor to this website and other online medical forums. I believe that testosterone is a very good hormone, and that there are many positive benefits to taking it. I recommend testosterone supplements for any health conditions that can be improved by testosterone. I've been prescribing testosterone products to men for over two decades. Many of these products were developed by Dr. John G. Wright of Wright Medical, Inc., and Dr. Robert L. Rehbein of the University of New Mexico. I've also been prescribing testosterone supplements to women for over 35 years, and have helped many women.
