Cortisol
Stress, recovery and peak performance
Elite athletes have measured their stress biology for years. Now you can do it at home.

Cortisol is called the stress hormone, but its role is far broader: it helps regulate metabolism, blood pressure, inflammation, energy and the sleep-wake rhythm. For years, testing it was reserved for elite athletes, who used it to understand recovery and whether they were adapting or being pushed too far.
Mayra Hurtado set out to bring that insight to everyone, with at-home salivary testing simple enough to use at home and credible enough to sell through pharmacies. She showed members how measuring your stress biology can lead to smarter decisions about health and performance.
