Hormonal
Total Testosterone
Primary androgen hormone — critical for muscle mass, bone density, energy, mood, and cardiovascular health.
Optimal Range
500-900 ng/dL (men) · 15-70 ng/dL (women)
Why It Matters
Testosterone declines ~1-2% per year after age 30. Low levels are associated with increased cardiovascular risk, sarcopenia, depression, and metabolic syndrome. Optimization is a key pillar of longevity medicine.
