Normal Hormone Levels
Below are listed normal levels
of IGF-1, testosterone, estrogen, estradiol, estriol, estrone, and progesterone.
Please note, all hormones decrease with age so the levels listed below are
what modern Western medicine considers "normal for age".
The decrease of these important hormones as we age plays a major role in bringing on the effects of aging.
IGF-1 levels reflect the amount of human growth hormone (the hormone of youth) in the body.
