1. Mush Magic Truffle Atlantis — 15 grams
Fifteen grams of fresh Atlantis sclerotia, rated 4 out of 5 for potency and 4 out of 5 for visuals on Mush Magic’s own scale. That puts it a clear step above the entry-level strains and a step below Hollandia and Utopia at the top.
It is also the strain in the range with the most interesting published chemistry: roughly 1,595 µg/g psilocybin against 85 µg/g psilocin in dried sclerotia. That ratio is nearly nineteen to one, and it tells you something practical about how the experience arrives.
Fifteen grams is comfortably one deep session or several lighter ones. Vacuum-sealed fresh and refrigerated from our cold storage to your door.
Legal status: Sclerotia are legal to buy, sell and possess in the Netherlands. When Dutch lawmakers banned psilocybin mushrooms in 2008 the prohibition was drawn along a botanical line: it named the above-ground fruiting bodies. Sclerotia, the underground nutrient reserves of the mycelium, fell outside that list. Almost no other country makes that distinction, and carrying truffles across a border is a separate matter from buying them here. Check your own law.

3. The ratio
Almost no truffle product publishes both alkaloids separately, and the Atlantis figures are worth reading because the ratio between them is not incidental.
- Psilocybin is a prodrug and psilocin is the active compound. Psilocybin does nothing until your body dephosphorylates it into psilocin.
- Atlantis is overwhelmingly psilocybin. Roughly 1,595 µg/g against 85 µg/g — about nineteen to one.
- Which means almost all of the effect arrives via conversion, rather than from psilocin that was already present in the material.
- And conversion takes time. That is a large part of why onset here is 30 to 45 minutes rather than immediate, and why the ninety-minute rule in section 4 exists.
- It also means it keeps better. Psilocin is the unstable one — it oxidises readily. Material dominated by psilocybin is inherently more stable in storage.
3.1 Reading potency ratings
The 4/5 rating is Mush Magic’s own scale, not an industry standard, and it is only comparable within their range. Within it, Atlantis sits above Mexicana and Tampanensis and below Hollandia and Utopia, which is genuinely useful information. Across brands, it means nothing.
The practical version: if the entry-level strains have felt too subtle, this is the correct next step. If you have not taken sclerotia at all, this is not where to begin.
4. Preparation and use
4.1 Getting it right
- A scale that reads tenths of a gram is the one thing worth owning for this.
- Light food two or three hours earlier, then leave it.
- Chew thoroughly, or brew. Off-the-boil water, fifteen minutes, sediment included.
- Ninety minutes before reconsidering. Onset runs 30 to 60 and sometimes longer.
- Clear the day and the evening.
4.2 Setting
- Someone stays sober and stays with you. They need to know what you took and roughly how much.
- Be seated or lying down before the first effects. Postural control is not reliable.
- Make the space safe first. No flames, no sharp or breakable objects, no stairs, no open windows.
- Keep a trip stopper to hand. Most are never opened; having one still helps.
- Nothing combined with it. No alcohol, no cannabis, no other substance, prescribed or otherwise.
4.3 Cautions
- Over 18s only.
- Not in pregnancy or while breastfeeding.
- Not for anyone with a personal or close family history of psychosis, schizophrenia, bipolar disorder or another serious psychiatric condition. Psychedelics can trigger episodes in people who are already predisposed — this is the caution that matters most on the page.
- Not alongside SSRIs, SNRIs, MAOIs or lithium without talking to a doctor. Lithium and psychedelics together have been linked to seizures.
- Nothing else in the mix: no alcohol, no cannabis, no other substance.
- No driving and no machinery for the rest of the day.
- Nausea in the first hour is normal. Something light a few hours beforehand helps.
- Fridge, sealed, away from children and pets.
Nineteen parts psilocybin to one part psilocin. Nearly all the effect arrives through conversion in the body, which is exactly why the onset is not instant.
- Fifteen grams of fresh vacuum-sealed Atlantis sclerotia, rated 4/5 for both potency and visuals.
- Published chemistry: about 1,595 µg/g psilocybin against 85 µg/g psilocin, dried.
- That psilocybin-dominant ratio means slower onset and better storage stability.
- About 1 g fresh to microdose; 7.5 g mild; 15 g full.
- The right step up from Mexicana or Tampanensis. Not a first purchase.
- Legal in the Netherlands as sclerotia. 18+ only.
- Order before 16:00 on weekdays for same-day dispatch in plain, unmarked packaging.
