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 2 chacun 15grm on as passer un super bon trip


    Decent trip
    as usual with this or utopia the trip is well worth it. would recommend this and utopia and yea take the whole lot. happy days


    i bought 2 packs of hollandia. Each for two people. it was our first high dose experience on psilocybin. (I only tried some shroom chocolate and psilocybe Atlantis, which didn't work as I was hoping for.) We ate the truffles and chewed them slowly. After 30 minutes I started to feel something rising up in my body. we giggled hard and listened to music. (Mostly death metal and tipper) We reached the peak after an hour and I was tripping balls. Never had so intense kaleidoscopic patterns and confused thoughts in my life. I had problems thinking rational. Nothing made sense, at the same time, everything made sense. Hard to explain. We started around 8pm. The trip lasted until 2am. We were inside the whole time. around 11 pm we felt tired and were fed up with tripping. we were concentrating on not dying mentally. I felt done and lifeless, had a wave of bad feelings. After an hour I felt better and I had some control of my mind back. the part after the peak was horrific, now I understand how psychopaths may feel like haha. It was still a good trip nevertheless. I feel more experienced in my mind due to facing my inner self. next time I'll be more prepared and outside in nature!


    Great effect !!


    Fantastici davvero!!
    Grandi effetti visivi, movimenti sciolti, euforia. Assolutamente da provare sono rimasto molto soddisfatto con una bustina intera da 15g.Oltre tutto un ottimo servizio, spedizione discreta e puntuale. Grande zamnesia! Buon divertimento.


    Thanks for the trip Zamnesia!
    The package arrived with stealth shipping. I tried to follow instructions and took about 8 grams and didn't feel anything for a couple of hours. Then I made a tea with the rest of the truffles and the trip started a few minutes later. It was fun and very eye opening. I will never forget this amazing experience. I recommend taking 15 grams for a good trip

    Beautifully brilliant.
    Took 15g just after waking up. Amazing. That is all.


    excellent products/excellent service
    an order was placed for these truffles and the package was lost in transit. Zamnesia replaced my whole order and added a little something extra as a goodwill gesture. the replacement order took just over a week to get to me but the wait was worth it. i shared the bag which weighed 16 grams between myself and a friend. the effects can be started to be felt after just 20 minuets and last for a good few hours before slowly fading off. 8 grams each was enough to feel the effects and have an afternoon of fun laughing but I will suggest that 8 grams is not quite enough to push you into that special place where reality fades away. next time i order from zamnesia I will order at least 2 packs and split between 3 people for a better experience. Thank you Zamnesia for providing great natural products that I am unable to obtain in my country.

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?
