1. High Hawaiians Magic Truffles — 25 grams
High Hawaiians is the strongest sclerotia product in the European smartshop market, and this is a 25-gram pack rather than the usual fifteen. Both of those facts should be read together before you buy.
Despite the name these have no connection to Hawaii and they are not botanical truffles in any sense. They are sclerotia: dense, hardened underground mycelial masses that certain fungi build as nutrient reserves when conditions turn hostile, packed tight by design.
Distributors routinely label them Psilocybe tampelandia. That name appears in no recognised mycological index — it is a trade invention. The cultures are more accurately placed in the Psilocybe tampanensis lineage, and the distinction matters if you are cross-referencing potency or storage data from anywhere else.
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. Pharmacology
Since this is the strongest product in the category, it is worth setting out precisely what is happening rather than describing effects:
- Psilocybin is a prodrug. It does nothing in that form.
- Alkaline phosphatase enzymes dephosphorylate it into psilocin. That metabolic step is why onset takes thirty to sixty minutes rather than arriving with absorption.
- Psilocin crosses the blood-brain barrier and acts as a partial agonist at the serotonin 5-HT2A receptor.
- That receptor activity disrupts default mode network connectivity, which is the current best account of why perception and thought shift the way they do.
- None of that scales gently. More material means more psilocin at the same receptors, and at this strength the step between amounts is large.
3.1 Twenty-five grams is not a dose
This is the point of the page. A 25-gram pack of the strongest sclerotia on the market is a supply, not a serving, and treating a pack as a unit is a mistake that a 15-gram pack of a mild strain forgives and this one does not.
- Weigh every amount on a scale that reads to 0.1 g.
- Reseal and refrigerate the rest before you begin, physically out of the room if possible.
- If you have used other truffles, do not scale by weight. Fifteen grams of Mexicana and fifteen grams of this are not comparable quantities in any useful sense.
- A sober sitter is not advisable here, it is required.
- If this would be your first truffle experience, buy something else. We would genuinely rather sell you the Mexicana.
Effects, onset and duration are governed by the amount, the individual and the setting — the same three variables as any strain, with far less room in each.
4. Preparation and use
4.1 Getting it right
- Use a scale that reads to a tenth of a gram. This is the one piece of equipment worth owning.
- Eat lightly two or three hours before, then nothing.
- Chew, or make a tea in hot but not boiling water. Fifteen minutes is enough.
- Ninety minutes before any second thought about more.
- Give the day to it. Four to six hours plus a tail, and a night you want free.
4.2 Setting
- Have a sober sitter present. Someone who stays sober, stays in the room and knows what you have taken.
- Sit or lie down before you start. Do not stand, walk or handle anything.
- Clear the space. No open flames, no stairs, nothing breakable within reach.
- Have a trip stopper to hand. Knowing it is there matters even if you never use it.
- Nothing else alongside it. No alcohol, no cannabis, no other substance.
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.
