Quick Answer: Apherma is a budget Amazon massage gun brand whose main model, the X8-G, publishes a 12mm amplitude and 30 speed levels (roughly 1,800-3,200 RPM) for a list price around $49.99 — often discounted to $22-35. The honest caveat: like Naipo, Apherma never publishes a stall-force figure, so there’s no verified number for how much resistance the motor can push through, and its 3,000mAh battery is non-removable, an added lifecycle cost hidden behind the low sticker price.
At under $50, Apherma sits well below the mid-tier brands this site usually reviews. What makes it worth a dedicated look rather than a passing mention is that it actually publishes more than most rock-bottom, no-name Amazon listings do: a specific 12mm amplitude figure, not just a vague “deep tissue” claim. A third-party review site, TheFamilyShed, rated the X8-G 91/100 and described its brushless motor as delivering “powerful percussive strokes with stable force” comparable to pricier rivals. That’s a real number and a real independent opinion — just not the specific stall-force test that would let it be compared apples-to-apples against brands like Ekrin or Theragun.

Recovery time is reading time — a free trial of Audible is worth starting while you wait for a sub-$50 gun like this to ship, especially since there’s no in-depth independent lab test to pore over first.
The honest gap: amplitude but no stall force, and a battery you can’t swap
Apherma clears a bar that trips up some of the cheapest brands on this site: it publishes a real amplitude figure (12mm) instead of hiding behind RPM alone, and unlike Aerlang, no independent review has come back disputing that number. But amplitude only tells you how far the head travels, not how much resistance it can push through before the motor bogs down — that’s stall force, and Apherma doesn’t publish it, the exact same gap this site has already flagged on Naipo. Without either a brand-stated figure or an independent lab test, there’s no way to know whether the X8-G holds up on a genuinely tight knot the way a rated-and-tested gun like the Ekrin B37 (56 lb, independently confirmed) does.
The non-removable 3,000mAh battery is the other tradeoff. TheFamilyShed’s own testing found real-world runtime varies sharply by speed — roughly 7-7.5 hours at the lowest setting, 3-4 hours at medium, and just 1.5-2 hours at the top of the 30-level range — reasonable numbers, but once that built-in cell degrades after enough charge cycles, the whole gun needs replacing rather than a swappable pack. Ekrin’s B37 line, by contrast, backs its battery with a lifetime warranty precisely because degradation is a known cost of daily use.
How Apherma compares to other budget brands
| Massage gun | Amplitude | Stall force | Price |
|---|---|---|---|
| Apherma X8-G | 12mm (published) | Not published | ~$22-49.99 |
| Naipo MGG-2103 | 12mm (published) | Not published | $129.99-$249.99 |
| Toloco EM26 | 10mm (published) | ~30 lb | ~$40-70 |
| Aerlang EM8 | 16mm claimed, disputed | 35lb claimed, disputed | ~$29.99-59.99 |
| Ekrin B37 | 12mm | 56 lb (independently tested) | ~$230 |
Apherma’s 12mm figure actually matches Naipo’s, but at roughly a fifth of the price — the difference is that Naipo has been on the market longer with design-award recognition, while Apherma is a newer, less-established Amazon-first brand with no stall-force spec to fall back on either.

Who should buy an Apherma?
Buy it if: you want the lowest possible entry price for a gun that at least publishes a real amplitude number rather than vague marketing copy — at $22-35 during a sale, the X8-G’s 12mm stroke and 30 speed levels cover light-to-moderate everyday recovery reasonably well.
Skip it if: verified power matters more than price — without a published or independently tested stall force, and with a non-removable battery that can’t be swapped once it degrades, buyers who need to punch through dense muscle should look at the Ekrin B37 or Toloco EM26 instead, both of which publish (and in Ekrin’s case, back with a lifetime warranty) real numbers.
The bottom line
Apherma clears a low bar that some sub-$50 brands miss — a real, undisputed amplitude figure — but it stops there: no stall force, no independent power test, and a battery that isn’t built to be replaced. At $22-35 during a sale, it’s a defensible rock-bottom pick for light use; if a verified stall-force number is what decides the purchase, see our best massage gun rankings for guns that publish and back it up.
