Well written book with some really great advice that helped this "older gal" feel more youthful and vibrant again. I followed the recommended advice to the letter, using the pellets and not oral meds or creams, and I really do feel better than I have in many, many years. It's great to finally sleep so soundly without needing to take the sleep aids that I've relied on for the better part of 20 years. I simply don't need them any longer, and the Testosterone has taken the edge off my hot flashes and night sweats to the point that they hardly bother me at all now. To me a great night's sleep is worth it's weight in gold, because it equates to having more energy during the day and no brain fog while I'm at work. I'm only a month in to this experiment and I'm told that I will continue to see improvements in other areas as well. I'm very pleased with my progress and have this author to thank for it.
