Stelo Glucose Biosensor
Stelo is the first FDA-cleared CGM specifically designed for non-insulin users, making it the premier choice for longevity enthusiasts. It utilizes the same high-accuracy sensor technology as the medical-grade G7 but optimized for metabolic health tracking without requiring a prescription.
Quality & Materials
The sensor uses a glucose oxidase enzymatic filament. The adhesive is a medical-grade, biocompatible acrylic-based pressure-sensitive adhesive designed to minimize skin irritation over a 15-day period.
Evidence & Testing
Leverages the same clinical foundation as the Dexcom G7, which shows a Mean Absolute Relative Difference (MARD) of approximately 8.2%, the industry benchmark for accuracy.
Brand Transparency
Dexcom is a publicly traded medical device company with rigorous FDA oversight. Stelo's software is purpose-built to show 'time in range' and glucose spikes rather than medical alerts, tailored for health-conscious users.
Value Assessment
At $99 for a 30-day supply (two 15-day sensors), it is currently the most cost-effective way to access high-end CGM hardware legally in the US without insurance coverage.
Why Not Alternatives?
Unlike the Dexcom G7 or Libre 3, Stelo does not require a physician's prescription or a third-party markup service like Levels or Nutrisense. It offers a longer 15-day wear time compared to the G7's 10 days, providing better value for those focused on long-term metabolic trends rather than acute insulin management.
