Several review sites call it a "peer-reviewed study." We traced it back to a master's thesis and a preprint pilot study — neither has actually been through peer review.
Pulsetto Fit is a wireless, neck-worn transcutaneous vagus nerve stimulator (tVNS). The underlying category has real, substantial research behind it — implanted VNS devices have decades of clinical use and FDA clearance for epilepsy and treatment-resistant depression.
Where things get murkier is the research specific to Pulsetto's own device. Multiple review sites describe a "2025 peer-reviewed study" showing increased alpha-wave activity and blood pressure effects. When we traced the actual sources, the picture looked different.
What we found: The device-specific research comes from a 2024 master's thesis (Erasmus University Rotterdam) and a small 2025 pilot study posted on Zenodo, a preprint repository. Neither has gone through formal peer review, and both involve small sample sizes and researchers with ties to the company. A properly designed, sham-controlled clinical trial of Pulsetto Fit is now registered and underway — a good sign — but it isn't published yet.
A real device using a real, well-studied mechanism (tVNS), built by a company that appears to be genuinely investing in better evidence going forward. The "peer-reviewed" framing used by several review sites doesn't hold up to scrutiny yet — worth knowing before you weigh that claim in your decision.

As far as we could confirm, no. The device-specific research comes from a 2024 master's thesis at Erasmus University Rotterdam and a small 2025 pilot study posted on Zenodo, a preprint repository — neither has gone through formal peer review.
No — the underlying category has substantial peer-reviewed research and decades of clinical use in implanted, FDA-cleared devices. What's thin is evidence specific to Pulsetto's exact device and parameters, not the broader mechanism.
