Kyle Drew sits in for Doug, and visits with Dr Scott Fogle of Life Extension. How to optimize hormone function in the body. Can you have ideal hormone levels without hormone replacement therapy? How has hormone replacement therapy changed from the early days of estrogen therapy for women, and bodybuilder-levels of testosterone for men? Can you be at "low-normal" levels of any hormone, but still need to bump it up to something more optimal? What happens when cortisol levels are too high or too low? Role of DHEA in hormone production, and the difference between regular DHEA and the 7-Keto form.
