Mush n Go reviews from our customers
Customer reviews
By the Mush n Go team · Updated 27 October 2026
Our customers post their reviews on Trustpilot. Here are ten of their reviews: on taste, energy, focus and delivery, and on what could be better too. Each one has been translated faithfully from French, with the first name, date and rating published on Trustpilot.
Most of our reviews are written in French: Mush n Go was born in France, where most of our customers are. Here are the most representative ones, translated from French: each review keeps the first name, date and rating published on Trustpilot, cut passages are marked […], and all the original reviews can still be read on our Trustpilot page.

Taste
A real coffee taste, with no mushroom taste.
It's the first question people ask us. Brainstoorm is based on roasted chicory with a coffee flavouring: the result is smooth, milder than an espresso, and it also comes in chocolate hazelnut.
“The coffee is really good, a bit different from a traditional coffee, it has a slight, very mild roasted taste […]”(translated from French)
★★★★★Nancy D. · 31 August 2026Trustpilot
“I love your coffee with that slight taste of chicory, I'm hooked on it now.”(translated from French)
★★★★★Didier P. · 28 August 2026Trustpilot
“Very good product, for me the afternoon crash has disappeared”(translated from French)
★★★★★Franck C. · 6 September 2026Trustpilot
What's in the cup
Doses shown to the milligram.
Brainstoorm combines three functional mushrooms, maca and ashwagandha, with just 20 mg of caffeine per cup, compared with around 80 mg in a regular espresso. Here is the recipe, exactly as it appears on the product pages.
| Per cup | Coffee flavour (6 g) | Chocolate hazelnut (8 g) |
|---|---|---|
| Lion's Mane | 1,000 mg | 1,000 mg |
| Cordyceps | 1,000 mg | 1,000 mg |
| Chaga | 1,000 mg | 1,000 mg |
| Maca | 3,000 mg | 3,000 mg |
| Ashwagandha | 40 mg | 200 mg |
| Rhodiola | — | 25 mg |
| Roasted chicory | 3,500 mg | — |
| Cocoa | — | 1,400 mg |
| NewCaff® caffeine | 20 mg | 20 mg |
| Total active ingredients | 6,040 mg | 6,225 mg |

Energy and focus
Steadier energy, without the jitters.
It's what comes up most often in the reviews: less caffeine than a regular coffee, and a more even day, without the afternoon slump.
“I particularly appreciate the steadier energy it gives: no jitters and no sudden tiredness.”(translated from French)
★★★★★Nawel F. · 7 January 2026Trustpilot
“I was sceptical and in the end I've been won over. Less caffeine and yet I'm full of beans and my mood is steady”(translated from French)
★★★★★Maïté S. · 4 April 2026Trustpilot
“I feel more focused and much less nervous”(translated from French)
★★★★★Roxane T. · 24 October 2025Trustpilot
“More mental clarity, more energy, and the famous 4 pm slump... gone and forgotten!”(translated from French)
★★★★★Virginie L. · 29 August 2026Trustpilot
Every experience is personal: a food supplement is no substitute for a varied diet and a healthy lifestyle.
The more nuanced reviews
What could be better, we show that too.
Not every review says “perfect from day one”. These ones talk about effects that take a little patience, a 4-star rating and delivery times that were long at the start.
“The first few days I didn't feel anything […] then it was in the second week that I started to feel motivated”(translated from French)
★★★★★Lenny M. · 27 June 2025Trustpilot
“[…] being able to access the lab analyses of the mushrooms and to actually check the stated doses”(translated from French)
★★★★☆Axel B. · 27 August 2026Trustpilot
“Admittedly, delivery times were long at the start, but now it's spot on.”(translated from French)
★★★★★Blandine · 7 September 2026Trustpilot
