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 pack of 15 grams (2 x 7,5 g) 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.

*Can be stored for a maximum of two months in the fridge. After you open the pack they can only be kept for two days.

    Title : Not so strong...
    Comment : Had a good wee night but no where near as strong as Zamnesia claim them to be I would advise taking more than one 15g pack..... My HOLLINDA pack was under the 15g so maybe that's why these were not that strong...... I could not see any visuals or colours like other these only gave me a nice relaxed feeling and that's it to be honest but not to happy at receiving under 15g and this was the 2nd pack I bought that was under the 15g and Iv only bought 3 times the other pack was 15.3g. These were received in the uk in 6 days from ordering day but yeah the only reason I gave 4 stars was because Zamnesia have great fast customer service or I would have only given these HOLLINDA 2 or 3 stars..... Xxx

    Title : EFFET MOYEN
    Comment : Bonjour à tous. Bien ressenti les effets... Manques d'intensité avec 15 gr... Peut-être atténués par les mojitos ! :)

    Title : Enlightenment
    Comment : Hi. Bought these week ago Was sceptical if they would even arrive in the post. To my amazement they arrived 5 days after I ordered. I took them.with 2 friends and went walking through fields. Ended up in a field full of horses that look like unicorns Went to a pub and ordered some beer. The drinks menu was 3d effect. The landscape looked HD and everything translucent. Felt being in a new dimension Everything glowing and melting Took 2 bags split between 3 people 5 out of 5. Thanks zamnesia!!!

    Title : Fantastische Sorte und Wirkung!
    Comment : Habe mir gleich zweimal 15g bestellt und beim ersten Mal 7,5g genommen. Dies war am Nachmittag bei wunderschönem Wetter auf einer Wiese - natürlich auf nüchternen Magen. Die Wirkung setzte cirka 45 Min. nach Einnahme ein und zog sich über 5 1/2 Stunden. Es war eine sehr schöne Erfahrung, vor allem da ich Sie alleine einnahm und alleine unterwegs war. Daher konnte ich mich voll auf mich selbst einlassen und habe hauptsächlich über mich selbst und mein Leben nachgedacht. Ich werde in 1 bis 2 Monaten erneut 7,5g zu mir nehmen und euch wieder berichten! Eine wunderschöne Erfahrung!

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?
