GSL 4-in-1 Cortisol Saliva Home Test Kit

Description

✨ Overview

The GSL 4-in-1 Cortisol Saliva Home Test Kit is an advanced panel that includes four individual cortisol saliva tests in one pack, so you can see how your cortisol changes across the day or over a short period of time. Saliva samples are collected at different time points (such as morning, midday, afternoon, and evening, as directed), giving you a daily cortisol curve instead of a single snapshot. Your samples are analyzed by LC-MS/MS for precise hormone measurement. This test provides information about cortisol rhythms and is not a diagnosis or a substitute for medical care.

 

🎯 Who this test is for

• People interested in their daily cortisol curve (for example, morning vs evening)
• Those with sleep problems, late-night alertness, or afternoon energy crashes
• Individuals working with coaches or clinicians on circadian rhythm or stress-support programs
• Anyone who wants a more complete view of how cortisol rises and falls across multiple time points rather than a single result

🧬 Biomarkers measured

This test measures cortisol and selected related adrenal stress markers in multiple saliva samples collected across the day to evaluate daily cortisol rhythm.
