1. Mush Magic Truffle Valhalla — 15 grams
Fifteen grams of fresh Valhalla sclerotia, and the most expensive product in the Mush Magic range. The name sets an expectation and the strain is built to meet it: a full session rather than an afternoon.
Sclerotia are underground masses of hardened fungal mycelium that certain Psilocybe species form as nutrient reserves under stress. They are morphologically quite distinct from a mushroom and chemically the same thing — psilocybin and psilocin.
Onset runs 30 to 60 minutes and the whole thing takes four to six hours. Section 3 walks through what those hours actually look like, because knowing the shape of a session in advance is the most useful preparation there is.
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 shape of a session
People prepare for the peak and get caught out by everything around it. Here is the whole arc, roughly, with the caveat that individual timings vary:
| When | What is happening |
|---|---|
| 0 to 30 minutes | Nothing, usually. This is the stretch in which people conclude it has not worked and take more. Do not. |
| 30 to 60 minutes | Onset. Often nausea, a shift in how light and colour look, sometimes yawning or a mild tremor. Heart rate and blood pressure rise transiently. Sit down. |
| 1 to 2 hours | Building towards the peak. Perception, thought and emotion all move. This is where a settled room and a sober sitter earn their place. |
| 2 to 4 hours | The peak and the long plateau. The bulk of the experience. |
| 4 to 6 hours | Coming down. Things resolve gradually rather than switching off. |
| Afterwards | An afterglow that can last into the next day, and tiredness. You will want to sleep. |
3.1 What to do with that
- Start it early. A six-hour experience begun at nine in the evening finishes at three in the morning, and the tail runs later than that.
- Eat before, not during. Something light two or three hours ahead. Eating mid-session is unappealing and unnecessary.
- Have water within reach and something warm for the temperature swings.
- Do not plan the day after either. The afterglow is pleasant; the tiredness is real.
- Set a ninety-minute rule and mean it. Almost every difficult session traces back to a second dose taken during that first quiet half hour.
The dose ranges themselves: 0.5 to 1.5 g to microdose, 5 to 10 g for something mild to moderate, and 10 to 15 g for the full experience the name is pointing at.
4. Preparation and use
4.1 Getting it right
- Weigh the dose on a 0.1 g scale and put the rest of the pack back in the fridge before you start.
- Eat something small a couple of hours earlier. Not a heavy meal, not an empty stomach.
- Chew slowly and thoroughly. Sclerotia are tough, and half-chewed material absorbs unevenly. A lemon or a strong juice makes it easier to get down.
- Set a timer for ninety minutes and do not consider more until it goes off. That is the rule that prevents most bad evenings.
- Have the day clear — four to six hours of effects and an evening you will not want scheduled.
4.2 Setting
- A sober sitter, in the room. Not next door, not on the phone — present, sober, and told what you have taken.
- Get down before you start. Sitting or lying. Never standing, never mid-task.
- Strip the room. Nothing burning, nothing breakable, no stairs and no open windows within reach.
- Trip stopper within arm’s reach. The reassurance is worth more than the capsules.
- On its own. No drink, no cannabis, nothing else in the mix.
4.3 Cautions
- You must be 18 or over.
- Do not use if pregnant or breastfeeding.
- Do not use if psychosis, schizophrenia, bipolar disorder or another serious psychiatric condition appears in your own history or in your immediate family. Psychedelics can bring on episodes in people already predisposed, and that risk is not reduced by taking less.
- No SSRIs, SNRIs, MAOIs or lithium without medical advice. The lithium combination in particular has been associated with seizures and other serious events.
- Nothing else alongside it — no alcohol, no cannabis, no other substance.
- No driving and no machinery for the remainder of the day.
- Expect some nausea in the first hour. A light meal a few hours earlier helps; an empty stomach makes it worse.
- Store in the fridge, sealed, and out of reach of children and pets.
The first half hour is where sessions go wrong. Nothing is happening, and that is exactly what is supposed to be happening.
