Biological Age Benchmark

Find Out How Old Your Body Actually Is.

Your birth certificate says one thing. Your biology says another. Most men your age are running a body that's 5-10 years older than it should be — without knowing it. This 2-minute benchmark scores your sleep, output, recovery, and hormonal markers to estimate your biological age gap. No fluff. Just data.

Built on real performance benchmarksThe same markers longevity researchers use to estimate biological age: VO2 max proxies, recovery velocity, body composition trends, inflammatory load, and hormonal output signals.
8 questions, 2 minutes, one numberYour biological age score tells you whether you're ahead of the curve or already falling behind your chronological clock.
Most men in their 30s fail at least 3 of these markers— and have no idea until their performance, recovery, or body composition starts going sideways.

Over 47,000 men have taken this benchmark. The average result: their body is running 6.4 years older than their calendar age. How do you stack up?
