The body has rhythms that are governed by a master clock that works much like a conductor. It strikes up one section of the body's orchestra as another quiets down, taking its main cue from light signals in the environment to stay in sync with the 24-hour day. Our body's hormones surge and ebb to this maestro's baton, controlling all endocrine function, predominantly a woman’s health for reproduction.

It is the circadian clock in our cells that measures one 24 hour spin of the planet. For 28 days the moon tracks the repeat of that cycle, and so does the body.

The Wiley Protocol uses these natural rhythms in nature to establish the proper doses of estradiol and natural progesterone that mimic the natural hormones which would be produced by your body if you were young. The topical creams and their amounts vary throughout the 28 day cycle to restore the hormone levels of youth because young women, for the most part, don’t have heart attacks, breast cancer, Alzheimer’s, osteoporosis, or type 2 diabetes.
