GO Microdose Review: What Is Actually Legal to Buy in the US?
GO Microdose is an Amsterdam retailer selling two very different catalogs under one roof: refrigerated strips of fresh psilocybin truffles, and a non-psychoactive range of functional mushroom gummies, single-species extracts and vitamins. Here is our analysis of what each one contains, what the labels publish, and where United States federal law draws the line.





Our verdict on GO Microdose in brief
GO Microdose is the store of GK Health B.V., in Amsterdam, and it sells two things that should never be evaluated together. The psilocybin side is built on strips of six separate one-gram portions of fresh Psilocybe mexicana sclerotia, from €18.00, with printed refrigeration and shelf-life rules, a user guide, a dosage calculator and structured courses. The non-psychoactive side is a well-specified functional range: Daily Gummies at $36.00 with 2,500 mg of a ten-mushroom blend per serving, every species named, fruiting body sourcing and a 10:1 extract, plus single-species Cōtae extracts and a vitamin shelf.
Two things decide the matter. Psilocybin is a Schedule I controlled substance under United States federal law, and the store's own page offering shipping to the US at $12 in 5 to 7 business days does not change that, so we do not recommend importing the truffle products. And no batch assay is published for any of them, which means one gram is a weight, not a standardized dose. For an American reader the usable part of this catalog is the functional mushroom and vitamin shelf.

In this full review we go through both halves of the GO Microdose catalog, what each label actually publishes, the shipping and returns terms, and the legal line an American reader has to know before ordering anything.

Our analysis of GO Microdose: the products under the microscope
This is an analysis of the official GO Microdose product pages and of the store's shipping and returns terms. There is no personal trial here, and on this catalog in particular there could not be one. The store is explicit about American orders: its own United States shipping page says it ships all its products to the US, from Amsterdam, by tracked Deutsche Post in 5 to 7 business days for $12, with an optional discreet-packaging add-on.
That fact needs its counterweight in the same breath. Psilocybin is a Schedule I controlled substance under United States federal law. A Dutch retailer accepting a US address and quoting a carrier does not make importation, possession or use lawful, and local reforms in some states do not override federal import rules. We do not recommend ordering the truffle or growkit products into the United States. The rest of the catalog, the functional mushroom gummies, the single-mushroom extracts and the vitamins, contains no psilocybin and is a separate question, which is why this page treats the two halves apart.
📌 Start as you wish: the beginner microdosing strip
This is the brand's entry point, and the first thing to correct is its format: it is not a capsule. One strip is a sealed blister of six separate one-gram portions of fresh Psilocybe mexicana sclerotia, produced organically in the Netherlands. It must be refrigerated, the brand gives it two to three months sealed and chilled, and it says one strip covers roughly two weeks on its own schedule. A user guide is included and the store links a dosage calculator.
The price is €18.00, listed at $21.75 in the store's dollar view, with quantity tiers at 10% from two strips, 12.5% from three and 15% from four. What no page provides, and this is the central limit of the whole category, is a psilocybin or psilocin amount per portion. One gram is a weight. Natural sclerotia vary in active-compound concentration from batch to batch, so a fixed gram is not a standardized dose, and it should never be read as one.
📌 Daily Gummies: the non-psychoactive mushroom blend
The Daily Gummies are the product a reader who cannot or should not buy truffles is most likely to want, and their page is better documented than the truffle pages. A jar holds 60 gummies, 2 a day for 30 days, with 2,500 mg of blend per serving. The ten species are named individually: maitake, shiitake, lion's mane, reishi, cordyceps, chaga, turkey tail, white button, black fungus and royal sun. The FAQ on the page states organic farm sourcing focused on the fruiting body, and a 10:1 extract.
The rest of the label is short and disclosed: glucose syrup, pectin, citric acid, natural raspberry flavor, sodium citrate, purple carrot juice concentrate and a vegetable oil of coconut oil with carnauba wax. Vegan, gluten-free, no GMOs, no gelatin, no alcohol and no food dyes, described as lab-tested for purity and potency. Price is $36.00, with the same quantity tiers as the strips. The gap is the one every blend has: the 2,500 mg is a total, with no split between the ten species and no beta-glucan percentage, so lion's mane could be 800 mg or 80 mg of it.
📌 The single-mushroom extracts and the vitamin line
Alongside its own gummies, GO Microdose distributes the Cōtae range, four single-mushroom extracts sold as a liquid or as capsules, lion's mane, chaga, cordyceps and reishi, each at $48.00. Buying one species at a time is the honest answer to the blend problem.
The store also carries a conventional supplement shelf: Ashwagandha KSM-66 at 600 mg and a magnesium bisglycinate complex at $36.00 each, zinc bisglycinate at 25 mg for $33.50, niacin at 100 mg for $21.75, plus 5-HTP sleep gummies and electrolyte gummies at $36.00. KSM-66 is a documented ashwagandha extract and bisglycinate is the better tolerated mineral form, so the sourcing choices are sensible.
The verdict on format and dosing
On format the brand is genuinely good. The strip separates portions physically so nothing has to be weighed, the shelf life and refrigeration rules are printed, a guide and a dosage calculator come with the purchase, and dispatch is same-day before 14:00. The store even sells a precision scale at $27.50 for people who prefer to weigh rather than trust a portion.
On dosing the picture divides cleanly. The functional products publish serving weights, and the vitamin line publishes milligram amounts. The psilocybin products publish a gram weight of fresh material and nothing else, which is the practice of the whole Dutch truffle market and remains its weakest point. A portion that looks standardized because it is sealed in its own compartment is not standardized in the way a supplement serving is.
Effectiveness and what to expect
Two very different bodies of evidence get confused around this brand. Clinical research on supervised psychedelic therapy uses medical screening, a defined substance at a defined dose, professional monitoring and follow-up. None of that applies to a strip of fresh truffles bought online and taken alone. Reported effects of psilocybin include anxiousness, panic, impaired judgment, nausea, perceptual changes and a raised heart rate; risk is higher with a personal or family history of psychosis or bipolar disorder; interactions with psychiatric medication need professional review; and driving, cycling or safety-critical work are incompatible with impairment. Pregnant or breastfeeding people and minors should not use these products.
The brand's own material does not keep that line. Its About page states that the company fights depression, anxiety and panic complaints and describes use as completely safe and natural, which no retail psilocybin product can support. The customer stories published on the site, several of them describing relief from serious symptoms, are testimonials: they cannot establish effectiveness or rule out placebo. On the functional side the wording that holds is narrower: the mushroom extracts are traditionally used and are being studied, magnesium contributes to the reduction of tiredness and fatigue, zinc to the normal function of the immune system. Anyone with a health condition or on medication should speak to a doctor first.
Who is GO Microdose?
GO Microdose is the store of GK Health B.V., an Amsterdam company registered at Joop Geesinkweg 601, 1114AB Amsterdam, Chamber of Commerce number 87887274, VAT NL864437584B01. Its own story page says it was founded by two entrepreneurs from Amsterdam working with a single supplier farm, and customer support runs Monday to Friday from 9:00 to 17:00 Central European Time.
The public rating to use is the store's Google reviews, 4.7 out of 5 across 303 reviews; there is no Trustpilot profile for this brand to report. Beyond retail, the company sells structured microdosing courses, downloadable guides and manuals, a dosage calculator and paid psychedelic coaching, which is a more supervised framing than most sellers in this market offer. What it does not publish is a certificate of analysis or an assay for any batch, on either half of the catalog.

Daily Gummies against a standard mushroom gummy
| Criteria |
Analyzed by TBS
Daily Gummies by GO Microdose
|
Standard mushroom gummy
|
|---|---|---|
| Species named | ✅All ten named: maitake, shiitake, lion's mane, reishi, cordyceps, chaga, turkey tail, white button, black fungus, royal sun | ❌Often just "mushroom blend" |
| Blend weight per serving | ✅2,500 mg for 2 gummies, 60 per jar, 30 days | ❌Frequently not stated |
| Mushroom material | ✅Fruiting body, 10:1 extract, per the brand's own FAQ | ❌Mycelium grown on grain is common |
| Amount per species | ❌No split published inside the 2,500 mg, and no beta-glucan figure | ❌Also usually absent |
| Other ingredients disclosed | ✅Full list published, glucose syrup first, no gelatin or food dyes | ✅Usually listed |
| Ships to the United States | ✅Yes, tracked Deutsche Post from Amsterdam, $12, 5 to 7 business days | ✅Sold on US shelves |
Judged only as a functional mushroom gummy, this one is above the category average: ten species named rather than hidden in a blend, a stated serving weight, fruiting body material and a 10:1 extract, and a full other-ingredients list. It stops at the same wall as almost every blend, the missing per-species split, and it is a gummy, so glucose syrup leads the base. The last line is a straightforward yes, and unlike the truffle half of this catalog, there is no legal obstacle to a US order of a functional mushroom product.
The GO Microdose range
Fifty-one listings, split into two worlds. The psilocybin side covers microdosing strips from $21.75, six varieties of magic truffle at $36.00 each, growkits at $59.75, and structured courses at $104.25 for beginners, $172.25 for the experienced level and $207.00 for the advanced one, with package deals from $92.25 to $161.25 and a paid coaching intake at $149.50.
The non-psychoactive side is the one an American reader can act on: the Daily Gummies, 5-HTP sleep gummies and electrolyte gummies at $36.00, the Cōtae single-mushroom liquids and capsules at $48.00, and a vitamin shelf from $21.75 to $36.00. Wellness stacks combining strips with supplements sit at $107.75, and accessories run from a $0.75 silica packet to a $36.00 vacuum container.
Composition breakdown: what the products are actually made of
The truffle strips, gram by gram
One ingredient: fresh sclerotia of Psilocybe mexicana, organically produced in the Netherlands, portioned into six one-gram compartments. No extract, no carrier, nothing added. That simplicity is also the analytical problem: because the material is fresh and natural, the psilocybin content of one gram is not fixed and the brand publishes no assay. Storage matters as much as the label, since the two to three month shelf life assumes the strip stays sealed and refrigerated. The other truffle varieties are different strains with no more published data.
The functional products, ingredient by ingredient
The Daily Gummies blend the ten species at a combined 2,500 mg per two gummies, described as a 10:1 fruiting body extract, on a base of glucose syrup, pectin, citric acid, natural raspberry flavor, sodium citrate, purple carrot juice concentrate for color and a coconut oil and carnauba wax coating. The Cōtae line takes the opposite approach with one species per bottle, which is the format to prefer if you want to know your dose. On the vitamin shelf, KSM-66 at 600 mg and the bisglycinate forms of magnesium and zinc are the well-documented choices, with the amounts printed.
Buying GO Microdose from the United States
The store ships to the United States and says so on a dedicated page: all products, from Amsterdam, by tracked Deutsche Post, at $12 with a 5 to 7 business day window, plus an optional discreet-packaging add-on and a warning that customs can delay tracking updates. Payment covers cards, PayPal, Revolut, iDEAL, SEPA and cryptocurrency.
None of that changes the legal position on the psilocybin half of the catalog. Under US federal law psilocybin is Schedule I, and importing it is a federal matter regardless of what a Dutch checkout accepts or what a state has reformed. We do not recommend ordering the truffles, the growkits or the microdosing courses into the United States, and this review does not price them as a US purchase. Read the returns terms before any order in any country: because the fresh products are perishable, GO Microdose states that returns are not possible, exchanges are limited to certain non-perishable items with return postage at your cost, and problems should be reported within about a day of delivery. The code LMC15 is listed at 15% off an eligible first order, which on the Daily Gummies at $36.00 comes to $30.60, the same reduction the store's own four-unit tier already gives.
Technical analysis and expert verdict
What GO Microdose does well is logistics and pedagogy. Portioned strips, printed storage rules, a dosage calculator, guides, courses and optional coaching add up to a more careful framing than most of this market, and the non-psychoactive half is genuinely well specified: ten named species, a stated serving weight, fruiting body material, a 10:1 extract and a full ingredient list on the gummies, plus documented forms on the vitamin shelf.
The reservations are serious and they sit on the other half. No batch assay is published for a natural psychoactive product whose potency varies, which means the portion size is a weight rather than a dose. The brand's own About page overreaches, describing use as completely safe and natural and framing the company around fighting depression, anxiety and panic complaints, which no retail product of this kind can support. And for the audience of this site the legal answer is unambiguous: psilocybin is federally Schedule I in the United States, so the truffle range is not a lawful consumer purchase there whatever the shipping page offers. If you are reading this from a US address, the useful part of this catalog is the functional mushroom and vitamin shelf, where the code LMC15 takes 15% off an eligible first order.
The GO Microdose flagship products
📌 Daily Gummies
The product an American reader can actually act on: 60 vegan gummies, 2 a day for 30 days, with 2,500 mg of a ten-mushroom blend per serving. All ten species are named, maitake, shiitake, lion's mane, reishi, cordyceps, chaga, turkey tail, white button, black fungus and royal sun, and the brand's FAQ states fruiting body sourcing and a 10:1 extract. Gluten-free, no gelatin, no GMOs, no food dyes, natural raspberry flavor, described as lab-tested. $36.00, or $30.60 with the code. The 2,500 mg is a total, with no split between the ten species.
📌 Start as you wish
The brand's entry point on the psilocybin side, and not a capsule: a refrigerated strip of six separate one-gram portions of fresh Psilocybe mexicana sclerotia, organically grown in the Netherlands, kept two to three months sealed and chilled, with a user guide included. €18.00, listed at $21.75 in the store's dollar view. Psilocybin is a Schedule I controlled substance under United States federal law, so we do not recommend importing this product into the US, whatever the checkout accepts.
The code LMC15 is listed at 15% off an eligible first order on the official store, which brings the Daily Gummies to $30.60.
