Age Intervention Medicine is a proactive approach to help you control how you age, rather than allowing the aging process to control you. With the right therapies, adjusting and optimizing hormonal imbalances, positive changes may include improved muscle tone, skin, energy, sex drive, mood, vitality, sleep, and decreased body fat.
