Psilocybe Hollandia


As its name suggests, Psilocybe hollandia is a new truffle developed and grown in the Netherlands by the country’s leading truffle producer. Nearly twice as strong as the other varieties, it’s already popular with experienced shroomers looking for a longer trip with more intense visuals (which hollandia delivers more reliably).

Though a tad more expensive, the hollandia does offer more bang for your buck – you can easily squeeze two trips from one 15 gram pack (in fact it’s recommended that all but the most experienced trippers stick to a half pack).

The taste has also been improved with a special growing method. The hollandia still has the nutty truffle flavour but without the sourness of other varieties.


All our Psychedelic Truffles contain psilocybin in more or less the same quantity. Their effects are also largely similar, though we've received reports that some strains trigger more social experiences, whereas others are more prone to produce visuals. Expections may however play a role in the eventual effects produced.

Once taken, you'll be able to feel the effects come on after about 15-45 minutes. Take stomach content and dosage into account as they can slow onset. After reaching their peak, the effects will gradually decrease again. The whole experience typically lasts about 4 to 6 hours.

You'll likely experience periods of laughter, increased energy, feelings of (universal) connectedness, philosophical thoughts and powerful hallucinations (some of which are visible with your eyes closed).


A naturally existing compound (similar to DMT in structure) called psilocybin is the substance responsible for the effects created by Magic Truffles. All our magic truffles are freshly packed in quantities of 15 grams. Truffles usually hold a lot of water though so while weightloss can occur and water is lost, the level of psilocybin will remain the same in them.
Psilocybin also doesn't create any bad byproducts or metabolites, which means: no hangover! Be ready to look at life differently though!


Mild, medium, or intergalactic is easy to figure out with our uncomplicated dosage calculator.

    A deux nous avons pris la moitié chacun et ce fut une expérience super intense, je recommande contrairement aux "utopia" que nous avons trouvé très faibles !


    Great trip
    We bought 2 packs of hollandia for 3 friends, really nice trip, vivid and colourful, inner peace and relax, will buy more for sure. We ate a bit more than 13g each


    First experience with Magic Mushrooms. Took all the bag. It was fucking awesome, but more spiritual than visual (just some deformations, not true hallucinations). Shrooms are made to teach you something. Don't waste this Nature gift for "fun" only. Psylocibin is ostia for all who love truth and want to know their roots. Enjoy !


    First time user. Took 15 grams at home alone. It was intense but I never felt scared. Lasted 6 hours and it was beautiful. For the best result be brave and do 15 grams. And have a intension with your trip. For me it was love and divine guidence. Dont forget music. It will guide you. I recommend shamanic music.


    great product! thanks Zamnesia.


    The shrooms came in a perfect condition, no mold or anything like that. Tasted fine, a bit nutty. it was my first shroom - experiment - and wow…. of course I didn´t follow the introduction. I was on holiday, it was afternoon, had breakfast and some Champagne… and I tooksome some little pieces, and I saw, yes, I like the feeling, I was just making a fantasy drawing, and the drawing got amazing. But at a certain point, I wanted more effects, and took a few bits more, and after a while… i was completey lifted up. I drank bottles of water, and tea, I was freezing, took a hot bath, and went with thick pullover into bed. My whole central nervous system was shaking me through - and I had visions, never seen before. Not on LSD nor on strong Cannabis either. I was part of a big, bright, colourful, mycelium, vivid colours, and patterns, and sympols. There was a door, I had to pass through… amazing. But as scientist I am always critical. The things you see are not real and you are not on higer level of evolution and psilocybin is no teacher, like a brand name may suggest. It teaches you nothing. Maybe it make you come into contact with your deepest fears or biggest energy. But everything you see is an illusion. Seeing it that way, it is relaxing to be in Wonderland. But what I learned as hard fact: It is a serious intoxication, in the case of shrooms are not so smooth like Cannabis, though not so earthshaking like LSD. Somewhere inbetween. Water always helps. Bad moments pass by. You can be sure. won´t miss the experience. It was great trip, thanks for that!


    que du plaisir!!

Wie lange halten sich die Trüffel in der Verpackung sodass sie noch frisch sind? Beispiel: Wenn eine Lieferung 3-5 Tage dauert, wie lange danach kann man sie noch mit gutem Gewissen verzehren?
