I have been using cBHT for over 10 years. I know it works for hot flashes and memory, as I had to postpone a doctor's visit and hence, a lapse in my prescription. All of those symptoms came rushing back until I was back on the correct dose. More importantly, I have no signs of osteoporosis and my younger sister who has not been on cBHT has severe osteoporosis. Now she is on heavy pharmaceuticals and is at an extreme high risk for bone fractures throughout her body.
