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.

    Rien du tout
    Après avoir avalé 7,5g chacun avec mon pote pour un premier trip avec des produits hallu je m'attendais a quelque chose. On a pu attendre longtemps,d'ailleurs on a jamais rien senti mais bon peut être que ça dépend des gens. Je retenterais peut être pour voir avec 15 g sinon ça sera les Valhalla :D


    These truffles are the strongest i've ever ate. I ate 11 grams. You get really euphoric feeling during trip. Closed-eyes visual were intense. I have never saw anything like that. Shipping was fast. Next time i will order vallhala truffles as they say they are strongest in the world. I will eat 11 grams as well just for comparison.


    un voyage spirituel
    je conseil a tous ceux qui ont eux un trip moyen ,d’écraser les truffes puis de les mettre dans un verre ,arroser d'un peu de jus de citron les truffes puis attendre 10 min.manger tout avec du chocolat ,miel pour ne pas trop ressentir le jus de citron car c'est pas appétissant et dure pour l'estomac. attention quand même soyer patient attendait 20min ,15g suffise très très bien avec le jus de citron ,bien mieux que de les mâcher et de les avaler personnellement . et la c'est la surprise assurée. j'ai donc commencer par les Valhalla pris directement 15g au bout de 8 min même pas mal, bon bizarre ça marche pas ,je décide de prendre 15g psy hollandia avec la même préparation , 5 min plus tard la claque de fou ,j'ai vite regretter d'avoir dit çà ! une gros montées d'euphorie ,les murs qui bouges ,tous respire dans ma maison ,je me suis mis sur le lit et regardant le plafond est la ,c'est l'alu total j'avais placer une lampe qui change de couleur whooo c'etais fantastique je me régaler a voir la lumière changer de couleur avec une musique zen au casque ,fascinant j'avais mes sens éveiller ,je voyer des univers de couleurs ,quel beauté suivi de crises de rire incontrôlable des penser créatifs ,une meilleur compréhension de soi même ,le plus beau voyage spirituel de ma vie grâce a zamnesia merci. je recommande les yeux fermer .


    Makes Under Siege 2 watchable
    A friend and me split the bag between us. We've both tripped before and were, for some reason, sceptical they'd have any effect. Definitely lots of fun though. No idea why, but we started watching Under Siege 2. I've seen it before and it's an awful, awful film, like really terrible, but we both sat through it and fucking loved it. We had absolutely no idea what was going on, laughed hysterically for a couple of hours and probably spent a good 20 mins stroking the curtains. So yeah, these truffles are good. Really good. Cheers fellas.

    Best Visuals and giggles!
    We've tried almost all of the varieties on this website, and these are hands down the best. We won't be using any other variety from now on. The service and delivery time is also really good. Thanks for doing a good job Zamnesia!

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?
