THE CHALLENGE
Out of sync cortisol? It’s probably working against your GLP-1.

Regular testing maps your cortisol curve over time, giving you data to optimize your GLP-1 use, not just guess.

What Eli users are saying
Cortisol tracking could complement existing devices. For example, if your smartwatch detects disrupted sleep, Eli’s Hormometer could help you see whether stress hormones are a factor.
