I have been using cBHT for close to 15 years. I am now 64. I started to use them to ease into menopause, and it worked. I didn't experience all the side effects I thought I would during menopause. I was able to work with my doctor to tweak the cBHT to suit me personally and over the years I have never felt better. I feel so much younger and have a great libido into my middle 60's. I feel really balanced and really couldn't be happier.
