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.

    Title : Deliciously
    Comment : I was hoping that it will come in 2x 7.5g but it was packed as one piece so I ate about 7-9g at 2 p.m. and I had a beautiful experience, it was very intense so when my thoughts was getting out of control I was thinking about my love, how much I love her... Visuals were very kind, all experience was very good but these truffles are definitely for experienced people with good spiritual control. At about 5 p.m. I took a warm shower to calm down a little bit, after that I fixed my mistakes in life that I saw in my trip... then at about 7 p.m. I ate the rest of the pack and in overall I was having a very nice experience that almost ended at about 11 p.m.

    Title : Grandios!
    Comment : Habe die Trüffel getrocknet und mir die ganze Packung genehmigt. Sehr angenehme Visuals, aber nichts im Vergleich zu Cubensis. Sehr philosophischer Trip, aber nicht überwältigend.

    Title : Altbewährt und immer wieder gut!
    Comment : Die guten Hollandia haben bisher jedes mal überzeugt. Ich möchte jetzt hier keinen ausführlichen Bericht über die genaue Wirkungsweise geben, da das vermutlich schon an anderer Stelle zur Genüge geschehen ist. Daher hier nur ein meiner Meinung nach sehr wichtiger Hinweis: Und zwar zur Dosierung: 15 Gramm sind für erfahrene User mit durchschnittlichem Körpergewicht von ca. 60 bis 80 kg eher niedrig dosiert. Wer etwas kräftiger ist, braucht auch als nicht erfahrener Psychonaut eine größere Menge für einen wirklichen und auch länger andauernden Trip. Bisher habe ich als erfahrener Pilzer (Körpergewicht ca. 70 bis 75kg) noch nicht mehr als 15 Gramm konsumiert und kann daher nichts zu einer Dosis von 20 Gramm sagen, die für das nächste mal angedacht ist. Ich vermute mal, dass man mit der Dosis ganz gut unterwegs sein dürfte. :-)

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?
