Visiting the Dexcom website for Stelo, it indicates a prescription will not be required. You can sign up to be notified when it's generally available:

I'm hoping it's priced reasonably for the short term.

The currently available Signos Dexcom G7 is being offered at $143/mo. for a 6-month plan. Signos is similar to Levels and requires a prescription and authorization to collect one's data during the subscription period. Both Signos and Levels will refer those interested to an online medical practitioner to provide the prescription.

For those who don't have diabetes and simply want to learn what spikes their BG, I'm hoping the Dexcom Stelo offers reasonable 3- and 6-month plans. That's about enough to experience "life" and monitor one's BG responses to make adjustments.
