Quick Answer: A Theragun is a massage gun — specifically, Therabody’s own brand of percussion massager, one of dozens on the market. There’s no separate category; “Theragun” just became the name most people reach for the way “Kleenex” stands in for tissue. Search demand backs this up: per Google Ads keyword data, “theragun” pulls about 90,500 US searches a month versus 135,000 for the generic “massage gun” — nearly matching volume. But unlike genuinely genericized brand names, Theragun’s trademark is still very much alive and enforced by Therabody, Inc.
If you’ve ever heard someone say “hand me the Theragun” while pointing at a no-name percussion massager, you’ve watched a brand name eat its own category — the same thing that happened to Kleenex, Band-Aid, and Q-tip. This guide untangles what’s actually true: whether “Theragun” and “massage gun” mean the same thing, why the confusion exists, and whether it still matters which one you buy.
Theragun is a brand. Massage gun is the category.
Therabody, Inc. (originally Theragun, Inc., founded by chiropractor Dr. Jason Wersland in 2008 and launched commercially in 2016) makes one specific line of percussion massagers: the Theragun Mini, Prime, Elite, and Pro. “Massage gun” — also called a percussion massager — is the generic term for the entire product category, which includes dozens of competing brands.
| Theragun (Therabody) | Other massage gun brands | |
|---|---|---|
| What it is | One manufacturer's product line | The entire product category |
| Examples | Mini, Prime, Elite, Pro | Hyperice Hypervolt, Ekrin B37, Bob and Brad C2, Renpho R3, Toloco EM26 |
| Price range (2026) | $199–$529.99 | $40–$350 |
| Amplitude | 16 mm (all current models) | 10–14 mm typical, varies by brand |
| Trademark status | Actively registered & enforced (Therabody, Inc.) | N/A — "massage gun" was never a brand name |
Theragun pricing per Therabody’s own store; amplitude figures per each brand’s published specs, 2026.
Reach for a real Theragun if the 16mm stroke, Therabody’s app-guided routines, and the flagship Pro’s OLED screen are worth the premium to you. If you’re ordering today and want it fast, an Amazon Prime free trial gets most massage guns to your door in two days, which matters more than the badge on the handle for a lot of buyers.
Why does everyone say “Theragun” instead of “massage gun”?
This pattern has a name in trademark law: genericide, or genericization — when a brand becomes so dominant that consumers start using its name for the whole product category, whether or not they’re actually holding that brand’s product. Theragun earned this the hard way: it was the first percussion massager to break into mainstream gyms, physical-therapy clinics, and pro sports sidelines, so it became the default word people reached for years before competitors caught up.
The search data shows just how far that’s gone. Per Google Ads keyword volume data, “theragun” draws about 90,500 monthly searches in the US — nearly matching the 135,000 monthly searches for “massage gun” itself, the actual category name. When a specific brand name pulls two-thirds the search volume of its entire product category, that’s a strong signal a large share of those searchers are using “Theragun” the way they’d use “Kleenex” — as shorthand for the product, not a request for that specific manufacturer.
By the numbers: “theragun” ≈ 90,500 searches/month vs. “massage gun” ≈ 135,000 searches/month (Google Ads keyword planner data, 2026) — a ratio genericized brand names typically show once they dominate a category’s search behavior.
Is Theragun legally generic, like aspirin or escalator?
No — and this is the part that’s easy to get wrong. Some famous brand names really did lose their legal trademark protection because courts ruled they’d become the generic name for the product:
- Aspirin — Bayer held the US trademark until a 1921 federal court ruling found the name had become generic for acetylsalicylic acid pain relievers.
- Escalator — Otis lost trademark protection after courts found “escalator” had become the everyday term for a moving staircase, not a brand.
- Thermos — the Second Circuit ruled in 1963 that “thermos” had become generic for vacuum-insulated containers, since the company hadn’t done enough to teach the public it was a brand name.
- Trampoline, cellophane, and zipper all followed the same path.
Theragun hasn’t crossed that line. Therabody, Inc. actively owns and defends a large trademark portfolio — well over 100 registered marks per Trademarkia’s ownership records, including “Theragun,” “Theragun Pro,” “Theragun Elite,” and “Therabody” itself. Colloquial overuse (calling any massage gun “a Theragun”) doesn’t strip a company of its legal trademark rights the way a court ruling does — that only happens through the kind of formal genericide finding that hit aspirin, escalator, and thermos. So while plenty of people use the name loosely, Theragun remains legally, exclusively Therabody’s.
So which should you actually buy?
Once you strip away the naming confusion, this is really a budget-versus-features decision, and the underlying science doesn’t care about the brand on the handle. Konrad et al. (2020, Journal of Sports Science & Medicine) found that five minutes of percussion therapy significantly improves range of motion with no loss of strength — a result about the technique, not any specific manufacturer, so it applies whether you’re holding a $529.99 Theragun Pro or a $70 Renpho R3.
- Buy an actual Theragun if you want the deepest 16mm amplitude across the whole current lineup, Therabody’s app-guided routines, or the Pro’s rotating arm and OLED screen — and $329.99–$529.99 isn’t a dealbreaker.
- Buy the Ekrin B37 ($229.99) if you want more stall force (56 lbs vs. the Prime’s 30 lbs, per each brand) and a lifetime warranty for less money.
- Buy a budget pick like the Bob and Brad C2 (about $100) or Toloco EM26 (about $40–$70) if you just want the percussion effect without paying for a name — see our full best budget massage gun roundup for more.
The bottom line
“Massage gun” and “Theragun” aren’t two different things — Theragun is one brand’s name for its massage guns, and it’s become so synonymous with the category that its search volume nearly rivals the generic term itself. That’s genuine brand dominance, not a legal loophole: Therabody still actively owns and enforces the Theragun trademark, unlike names such as aspirin or escalator that courts have ruled fully generic. Whether you buy the real thing or a competitor, the technique — and the research behind it — works the same either way.
