Your stress has a daily rhythm.

Morning

Cortisol peaks after waking, priming your body for training. On flat, sluggish mornings, this window is worth checking.

Evening

By night, cortisol should drop. Test before bed to learn if it's staying high, cutting into your sleep and recovery.

Day-to-day: your pattern

Regular testing can show if your body is absorbing training load or straining beneath it so you can adjust.

Eli's cortisol tests are a game changer. They are super easy to use, and the UI in the app is well designed. I'm able to reliably test my cortisol throughout the day and understand if I'm at, above, or below baseline. It's helping me figure out what's triggering cortisol spikes and leading to me getting better sleep!

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.

5.0

I have a history of chronic insomnia which I figured was stress related, causing a premature spike in my cortisol in the middle of the night - causing me to awake and unable to sleep. The home cortisol test helped to confirm this and was easy to use.
