Psilocybe hollandia

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.


As a rule, all truffles have a high level of psilocybin in them, so the effects of all of them are broadly similar. But P. Hollandia is the exception. With twice the level of psilocybin, its visual effects are more colourful and overwhelming than any other variety, and the trip will be longer than the usual 4-6 hours (but not double).

Effects will be felt within 15-45 minutes of consumption, depending on how many you took and how long since your last meal. A typical trip consists of a ‘coming up’ period, an experience plateau, followed by a gradual descent back to normal consensus reality.

The effects include: outbursts of hilarity, changed colour and sound perception, introspective thoughts, feelings of universal connectedness, waves of energy coursing through the body, vivid visions with eyes closed.


The active ingredient in truffles is psilocybin, a triptamine similar in structure to our bodies’ naturally produced neurotransmitter, DMT. There are no poisonous byproducts or metabolites created – psilocybin is ridiculously non-toxic - so no hangover. But you may look at life a little differently the next day!


Hollandia are sold in a duo-pack of 2 x 7.5 grams so you can easily split the 15 grams of truffle. Although this weight may be reduced as water is lost during shipping & storage, the effects are the same.

Truffles are sold fresh so you need to keep them in the refrigerator until you use them. Take 7.5 grams for a normal trip and 10 - 15 grams for a strong trip. Try to eat them raw on an empty stomach for best results, or crumble then and boil them gently for 20 minutes to make a tea, which can be sweetened (with honey, not sugar).


Avoid using when pregnant or nursing, when depressed, on medication or in combination with stimulants or alcohol. Also avoid driving motorized vehicles. Not suitable for under-18s. If it’s your first time on psilocybin it’s a good idea to have a friend with experience to be with you in case you feel nauseous or anxious. Do not repeat a trip for at least a week – not because it’s dangerous but because it’s a waste of money! The body rapidly builds up a tolerance for psilocybin so taking a fresh dose too soon after the last one will have no effect.

    Comment : Mein Problem bei den Hollandia war, dass sie so eklig geschmeckt haben, das die sie nicht essen konnte... nach jedem versuch einen extremen Würgreiz bekommen! Habe es dann mit Joghurt zusammen versucht. Habe es aber trotzdem nicht gschafft :/

    Title : Good!
    Comment : Un bon staff, mais il faut bien prendre tout le sachet pour sentir un bon effet, le trip est trankil, pas de bad pas trop visu juste les couleurs intensifiées etc. durée 5h, lendemain un peu de courbatures, mais ça c'est si vous avez fait un peu le pitre, et avec ces truffes ya de koi, controle du trip sans pb. Je les conseille même aux novices... Pour avoir vrémaint une Exp. forte il faut au moins le double de ces champis. Une expérience sympa pas très forte et pas très faible, juste ce qu'il faut.

    Title : WoW!
    Comment : 10grams of hollandia is My breakfast and dinner. It start kick in just 45min hole new world twisting images when I closed my eyes . I have very old paintings and it was very nice to see them alive finally . How ever I like Atlantis more. It is not so intense like this one. It is more chilling like for me . First timers should not choose hollandia it's too much to handle. If one takes truffles first time they should choose Mexican.

    Title : Enorme
    Comment : C'est clairement des truffes énormes. Il faut 3/4 de sachet pour bien décoler, mais avec ça, vous ferez un trip de 4h vraiment ouffissime. Avec un peu de salvia pour mettre de bonne humeur éventuellement, pour ceux qui ont peur du bad trip...

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?
