At almost 50 years of age with hyperthyroidism my thyroid gland was totally ablated with RAI. At that time my peri-menopause became menopause. A physician prescribed Premarin and a very negative experience followed with multiple side effects. Obviously my body was not accepting the Premarin so I discontined this drug. A friend introduced me to the cBHT. After beginning this therapy there was a feeling of calm in my body with absolutely zero side effects. To this day at 74 years of age I continue to take this hormone therapy and will until I die. This natural estrogen and progesterone balances my body and has enabled me to gracefully grow old .......more youthfully than many peers not taking natural hormone therapy. I am blessed.
