Hollandia Magic Truffles – 15 grams
Psilocybe Hollandia is a cultivated variety developed in the Netherlands with the aim of achieving a higher psilocybin concentration than common strains such as Mexicana or Tampanensis. The result is a sclerotium that consistently falls into the higher potency class, comparable to Space Invaders and Double Vision. The taste is slightly milder than that of some other potent strains, making immediate consumption more pleasant.
The active compound psilocybin is converted into psilocin after ingestion, which acts as a partial agonist on the serotonin 5-HT2A receptors. At higher doses, this leads to pronounced changes in the perception of color and shape, time perception, and the capacity for self-reflection. Hollandia is known for a relatively rapid onset and a distinct peak.
Dosage
Taking on an empty stomach provides the strongest and most predictable effect. The correct amount depends on your body weight, whether the truffles are fresh or dried, and how intense you want the experience to be. Use the calculator below to determine your personal starting dose:
The first effects are noticeable after 20 to 40 minutes. The total duration averages between 3 and 5 hours. Due to its high potency, it is especially important with Hollandia to start low if you are using this strain for the first time, even if you have experience with milder truffle strains.
Usage
The most direct method is to eat the truffles whole or in small pieces on an empty stomach. If you’re prone to nausea, it’s better to make tea: finely chop the sclerotia, pour water at a maximum of 70°C over it, and let it steep for 10 to 15 minutes. Strain out the solids and drink the tea slowly. The steeping process can be repeated for a second, milder serving.
Combining with alcohol or other psychoactive substances is strongly discouraged. The interaction is unpredictable and significantly increases the risk of an unpleasant experience.
Storage
Store the truffles unopened in the refrigerator at 2–4°C until the expiration date. Consume as soon as possible after opening. A slight blue discoloration due to damage is normal and indicates oxidation of psilocybin, not spoilage.
Harm reduction
Due to its high potency, Hollandia is not suitable as a first introduction to truffles. Use this strain only if you are feeling well, both mentally and physically. Avoid use if you have a history (personal or familial) of psychosis, schizophrenia, or bipolar disorder. Do not combine with SSRIs, lithium, or MAO inhibitors. Ensure a safe environment and have a sober person present who is not using the product. You can find more background information on safe use in our knowledge base.
Available exclusively to individuals 18 years of age and older.
Frequently Asked Questions
Is Hollandia suitable as a first truffle experience?
Not recommended. Hollandia falls into the highest potency class and, at a full dose, provides an intense experience that can be overwhelming for inexperienced users. For a first introduction, strains like Mexicana or Pajaritos are a better starting point.
What makes Hollandia different from other Dutch truffle strains?
Hollandia is specifically cultivated in the Netherlands to achieve a higher psilocybin concentration than standard strains. This makes the strain significantly stronger per gram than, for example, Atlantis or Tampanensis, while the taste remains relatively mild for a potent strain.
How strong is Hollandia compared to High Hawaiians?
Both strains fall into the highest potency class. High Hawaiians are sometimes described by users as having a slightly earthier and longer-lasting effect, while Hollandia is known for a clearer, visually active experience. Which strain is stronger depends heavily on individual sensitivity and the batch.
Can I also add the truffles to food?
Technically, yes, but heating above 70°C breaks down psilocybin and significantly reduces the effect. So only add the truffles to a dish after cooking, or brew tea at a low temperature. The most reliable method remains eating them directly or brewing tea below 70°C.
