I started BHT in 2004 at age 52. My anti-aging physician monitored my hormones carefully and made recommendations. At age 59 I was able to donate my kidney to my 29 year old son and save his life. I have the kidney(s) of a 30 year old according to the nephrologists at Northwestern Memorial Hospital in Chicago. I also donated three rounds of stemcells which were also given to my son at the time of his transplant as part of an NIH study. I was able to do all of this because my BHT built me up at a time in my life when most women are aging. I have bone scans that show +5 +6 +3 bone density, I am on no medication except the BHT. My blood pressure is 100/60. I do yoga every day and walk two-three miles several times a week. I am now 66 years old. I look 10-15 years younger than I am. I know these hormones make a huge difference and prevent ailments in older people.
