Why Don't Massage Gun Brands Disclose Stall Force?
Non-disclosure of stall force is common in this category, and it is itself a finding worth reporting, not a data gap to gloss over. Amplitude and RPM are published on nearly every massage gun's marketing page because they are easy, single numbers to headline. Stall force requires an actual load test, and several widely sold brands simply don't publish one.
The one thing to know: Non-disclosure of stall force is extremely common in this category, and it is itself a meaningful finding, not a data gap to gloss over. Several widely sold models publish amplitude and RPM prominently while omitting stall force entirely, or publish it only through third-party review testing rather than an official spec sheet. When a brand omits stall force, that omission does not tell you the device performs badly under pressure — it tells you the brand chose not to make that specific, verifiable claim, and buyers are left to rely on independent measurement or their own testing.
What we found across 16 popular models
In our Stall Force Reality Index, Theragun (across all four models we checked) and Ekrin's B37S both publish stall force directly, with Ekrin going further by disclosing a per-speed-setting range (36-56 lbs) rather than one peak figure. By contrast, Hyperice's standard Hypervolt 2 and Opove's M3 Pro Max had no verifiable stall-force figure from either a manufacturer page or an independent third-party test at the time of our research.
What non-disclosure means (and doesn't mean) for buyers
A missing stall-force spec does not mean a device performs badly under pressure — it means that specific, verifiable claim was never made publicly. It does mean you have one less data point to compare that model against ones that do disclose it, and it's a legitimate reason to look for independent, third-party test coverage of that specific model before assuming its unloaded amplitude spec tells the whole story.

Frequently Asked Questions
There's no universal disclosure standard for the category, unlike amplitude and RPM which nearly every brand publishes prominently. Stall force requires a specific load test to measure, and a brand that doesn't publish one hasn't necessarily performed or verified the measurement at all.
Non-disclosure means a specific claim wasn't made — it does not by itself mean the device performs poorly under pressure. It does mean buyers have less information to compare that model against ones that do publish the spec, which is a real information gap worth knowing about before buying.
Theragun (Therabody) and Ekrin both publish stall-force figures on their own product pages, with Ekrin notably publishing a per-speed-setting range rather than a single peak number. See the full comparison in our Stall Force Reality Index.
In our dataset, Hyperice's standard Hypervolt 2 and Opove's M3 Pro Max did not have a stall-force figure we could verify from a manufacturer spec sheet or a third-party measurement at the time of research.
