Understanding Age-Related Changes

Early Adulthood (20-30)

  • Testosterone levels peak in early adulthood
  • Levels typically range from 600-900 ng/dL
  • Optimal for muscle growth, energy, and libido

Middle Age (30-50)

  • Gradual decline begins around age 30
  • Average decline of about 1% per year
  • Levels remain sufficient for most men’s needs

Later Years (50+)

  • More significant decline in testosterone production
  • Many men experience symptoms of low testosterone
  • Lifestyle factors become increasingly important
