Breakthrough scientific tools available for everyone.
101+ is now available on the App Store for iOS, and on Google Play for Android. Download the app and become a Foundation or Infinity Member today.
Infinity Members can schedule their 101+ test directly through the app. This comprehensive, clinical-grade assessment is designed to decode your biology, measure your Aging Speed, identify its Root Cause, and guide you toward a longer, healthier life.
Your Aging Speed shows how fast your body is aging compared to your actual age.
A slower Aging Speed means your body is aging more slowly than expected for your age, which is associated with better long-term health and more healthy years of life.
For example, if your Aging Speed indicates you are aging 2.5 years slower than your chronological age, it suggests your body is functioning more like someone 2.5 years younger.
Someone’s Unique Root Cause of Aging (RCA) identifies the main biological factors driving your Aging Speed. It highlights what is most contributing to faster or slower aging in your body.
101+ is currently available across the United States. You can access everything through the 101+ app, and your test will be completed from the comfort and privacy of your home. No clinics. No waiting rooms. Just clinical-grade insights, delivered on your terms.
