Biography
Dr. Whitfield has spent more than 15 years in outpatient internal medicine with a focus on cardiovascular risk reduction and age-related testosterone decline in men. He reviews XT Guide articles covering cardiovascular health, hormone panels, and integrated men's-health topics.
His clinical priority is helping men interpret labs in context — testosterone, lipids, insulin, and inflammatory markers together — rather than in isolation.
