Morning
Your morning cortisol peak can show up hours late, leaving you sluggish and tired.

Evening
Cortisol’s evening drop comes too late, leaving you feeling wired and on edge.

Your full rhythm
Your real recovery window is how long your peak takes to realign. Tracking helps you know when you’ve reset.
These really helped me get an idea of my natural circadium rhythm. It was much more useful than going to my doctor who charged $400 for 1 test.
UltraGeek1111, Verified Buyer
Really helps with immediate feedback about cortisol trends in real time! Instead of waiting for 3-4 weeks for traditional test results I can access the data immediately.
Peter, Verified Buyer
Very simple, easy to use test. Helped me to determine if my late night wakings were due to cortisol spikes.
