[Solved] What can you expect from a first psilocybin therapy session?

A psilocybin pathway in Triptherapie is not a standalone psychedelic experience, but a carefully constructed journey. The difference lies not only in the substance, but primarily in the way it is used: as part of in-depth, professionally guided psychedelic therapy.

Psilocybin therapy versus “a guided trip”

Many people have heard about truffle ceremonies or psychedelic sessions with a facilitator. What we do goes a step further. At Triptherapie, we work with therapists specializing in EMDR, somatic therapy, Internal Family Systems (IFS), psychodrama, and psychology, among others. This is combined with extensive experience with psilocybin and other psychedelics.

That means that when during your session:

• stuck traumatic memories resurface
• split-off parts of yourself become visible
• intense physical release takes place
• deep attachment or existential themes surface

so that we not only “hold space,” but can intervene therapeutically. Consider applying EMDR principles when trauma material presents itself, guiding body-oriented release via somatic techniques, or working with inner parts via IFS.

The difference between a facilitator and a trauma therapist is fundamental in this regard. We focus not only on experiencing insights, but on actually processing and integrating the underlying causes of psychological suffering.

1. The intake: foundation of safety

A process always begins with an extensive screening via the intake:  https://triptherapie.nl/intake-triptherapie/

Here is what we look at:

1. Mental and physical health

2. Medication use

3. Trauma background

4. Previous therapies

5. Your request for help and intention

We honestly discuss your relationship with control, your capacity for surrender, and any fears surrounding the process. This is not a formality, but the foundation of safety.

Sometimes a psychedelic session proves appropriate. In other cases, we recommend stabilizing work or another therapeutic course first. We can also refer you to a general practitioner or psychiatrist if we believe that we can still schedule a session with some additional help.

2. The preparation phase: weeks before the session

Your first experience does not begin on the day you take the truffles. The real start lies weeks earlier.

During the preparation:

1. we delve into your personal history

2. we investigate recurring patterns

3. we identify possible triggers

4. we practice nervous system regulation

5. Do we improve neurochemistry with supplements and/or nutrition?.

You learn to recognize when your system becomes activated and how to ground yourself. This proves to be incredibly valuable during the session: you already have tools to deal with intensity.

We formulate your intentions together. What do you want to explore? What are you willing to let go of? What do you desire clarity about? At the same time, we teach you to hold that intention lightly. Psilocybin often has an intelligence of its own and brings forward what truly requires attention.

3. The session itself: the journey

The session takes place at your own address, location, or at one of our locations.

A session lasts an average of 5 to 7 hours. The dosage is tailored to your background, sensitivity, and specific needs. This usually takes place within an individual process, but some who require less guidance opt for the group ceremonies.

During the trip:

1. can you work with an eye mask and music for deep introspection

2. or instead stay in contact with your therapist

3. the therapist remains actively/inactively present based on need

4. somatic interventions are applied if necessary

5. can EMDR elements be integrated upon trauma activation

6. we guide you in working with inner parts

You may experience intense emotions, such as sadness, joy, grief, or being moved. You may have mystical or spiritual experiences, or conversely gain clear psychological insight into patterns that have been stuck for years.

Important to understand: there is no “right” experience. Whatever presents itself is exactly what is healing at that moment. Our role is to help you stay with it, feel it fully, and utilize it therapeutically.

Neurobiologically, psilocybin is converted into psilocin, which reduces the activity of the Default Mode Network. This results in increased cognitive flexibility and temporary neuroplasticity. This acts as a kind of time window in which new connections become possible.

4. The integration phase: this is where lasting change occurs

What many people underestimate is that the real transformation takes place after the session.

Research shows that psilocybin triggers a period of increased neuroplasticity that can last for weeks. During this period, the brain is particularly receptive to new patterns, beliefs, and behavioral change.

During integration sessions:

1. we analyze the insights gained

2. we process any remaining trauma material

3. we translate symbolic experiences into practical steps

4. we help you anchor new patterns

As standard, at Triptherapie we offer one integration session per private session or truffle ceremony. For the psychedelic retreats, we also have an integration day following the truffle ceremony day. And you can opt for extra integration or group integration.

5. Is this program suitable for you?

A psilocybin journey works best when you are willing to do deep work. View psychedelic therapy primarily as a catalyst for therapy and personal growth.

It often suits people who:

1. have already undergone therapy but still feel stuck

2. understand their trauma rationally but still experience physical insecurity

3. struggling with treatment-resistant depression

4. carrying complex traumas

5. have existential anxiety or questions about the meaning of life

6. experiencing recurring relationship patterns

It is important that you are willing:

1. to take the preparation seriously

2. to surrender to the process during the session

3. to actively participate in integration

6. How much progress can you expect from one session?

Psychedelic therapy is not yet a medical treatment in the Netherlands, and all medical claims must first be scientifically investigated. Studies currently indicate a reduction in depression and anxiety symptoms of approximately 70% after 1, 2, or 3 psilocybin sessions. Some are declared in remission after just one session. We see similar effects in practice. However, it is important to remember that although it can offer significant improvement for most people, there is also a group that notices little to no improvement. These are often neurodivergent individuals. Additionally, some psychiatric conditions may actually worsen. Proper screening is therefore important.

Conclusion

A complete psilocybin program at Triptherapie consists of:

1. Thorough intake and screening

2. Intensive preparation with therapeutic techniques and health improvement + neurochemistry

3. Professionally guided session

4. Integration within a neuroplastic window

5. Possible follow-up process if necessary

The goal is not only a special experience, but structural change at the level of the nervous system, beliefs, and identity.

What can you expect?

What happens during a magic truffle session? How long does a trip last, and what can you expect when taking psilocybin under supervision?

Perhaps you want to understand what such an experience feels like. Perhaps you are considering a session and want a realistic picture of what to expect. Or perhaps you have already read about it and are curious about how it works in practice.

In this article, you will read how a psilocybin session proceeds, from preparation to completion. No mystical stories or complicated jargon, but a clear and practical explanation.

In short: what do you expect during a psilocybin session?

A psilocybin session typically lasts five to six hours from the moment of ingestion. The most intense phase usually occurs between one and a half and three hours after consuming the truffles.

During the experience, your consciousness changes temporarily. Colors may appear more intense, time may feel different, and thoughts are experienced in a different way.

The quality of the experience is strongly influenced by preparation, or set and setting. This often makes more of a difference than the exact dosage.

Guidance contributes to safety and calm, without active therapeutic intervention.

No truffle journey is the same. Some sessions are calm and introspective, while others are emotional or insightful.

What is a psilocybin session?

A psilocybin session is a guided experience in which you consciously ingest magic truffles within a safe and peaceful environment.

The active ingredient in magic truffles is psilocybin, a natural psychedelic compound that temporarily alters consciousness. In the Netherlands, magic truffles are legal. Magic mushrooms contain the same active ingredient but fall under Schedule II of the Opium Act.

Although the word 'session' sounds formal, it is primarily about consciously creating time and space for the experience, with a facilitator ensuring safety.

How does psilocybin work in the brain?

After ingestion, the body converts psilocybin into psilocin within fifteen to forty-five minutes. Psilocin is the substance responsible for the psychedelic effects.

Psilocin is structurally very similar to serotonin, a neurotransmitter involved in mood and perception. The substance binds primarily to 5-HT2A receptors, leading to the characteristic effects of a trip.

An important mechanism is the temporary suppression of the default mode network (DMN). This network plays a role in self-reflection, rumination, and fixed thought patterns. By reducing this activity, many people experience greater mental flexibility.

What happens during the session?

During a psilocybin experience, perception changes noticeably. Sensory impressions can become more intense, the sense of time can shift, and thoughts take on a different character.

How this is experienced varies from person to person and depends on factors such as mental state, environment, dosage, and individual sensitivity.

Preparation: set and setting

A psilocybin session actually begins before ingestion. Preparation plays a crucial role.

Mental state (set)

Your psychological state strongly influences the experience. Calmness, tension, curiosity, or restlessness can all carry over during the trip.

It is not necessary to be completely in balance, but awareness of your current mental state helps.

Many people choose to live more quietly beforehand. Fewer stimuli, fewer obligations, more relaxation.

An open and curious attitude is often supportive.

Environment (setting)

A quiet, familiar environment without unexpected disturbances increases the sense of safety.

Soft lighting, comfortable seating or reclining areas, and optional supportive music contribute to relaxation.

In group sessions, the presence of others can actually provide a sense of security, while everyone goes through their own inner process.

Practical preparation

Eating a light meal beforehand is often experienced as pleasant. Both a full and a completely empty stomach can cause discomfort.

Make sure your schedule is free after the session. Time to settle in and process is important.

Comfortable clothing is recommended, as body temperature can fluctuate.

The phases of a psilocybin experience

Although every experience is unique, a session usually follows a recognizable pattern.

Phase 1: initial phase (0–45 minutes)

The first effects usually occur between twenty and forty-five minutes after ingestion.

Physical sensations such as mild restlessness or stomach activity are normal. Mild nausea sometimes occurs.

Staying calm helps this phase proceed smoothly.

Phase 2: turnout (30–90 minutes)

Perception and thoughts begin to change clearly.

Many people experience wonder, sometimes combined with slight tension as the sense of control diminishes.

Guidance plays a stabilizing role here.

Phase 3: climax (1.5–3 hours)

This is the most intense phase.

Visual changes may occur, ranging from subtle to pronounced.

Emotions can deepen or intensify. This is not necessarily negative, but it can be confronting.

The perception of time often changes noticeably.

Thoughts and insights may arise, but are not guaranteed.

There is no right or wrong way to experience this phase.

Phase 4: descent (3–5 hours)

The intensity gradually decreases.

Many people experience calm, clarity, and mild fatigue.

Sensory effects become softer.

Phase 5: afterland (5–6 hours and later)

The psychedelic effects largely disappear.

Mental or physical fatigue may still be present.

Rest, food, and hydration support recovery.

The role of guidance

Guidance focuses on safety and presence, not on active therapy.

A support worker provides stability, monitors the setting, and supports when necessary.

Non-directive presence is central.

Individual or group

Individual sessions offer maximum privacy and personal attention.

Group sessions offer shared space and often a sense of connection.

Both forms have their own dynamics.

Difficult moments during the trip

Not every experience is completely pleasant.

Anxiety or emotional intensity may occur.

This is not automatically a negative experience.

Acceptance and breathing often help better than resistance.

Guidance and minor adjustments to the environment can provide support.

Attempts to stop the trip are usually ineffective.

After the session

The experience ends, but the processing continues.

Rest and reflection in the days that follow support integration.

Some experience an afterglow, while others experience emotional sensitivity.

Both reactions are normal.

Integration means giving meaning to the experience in a way that suits you.

Suitability

Psilocybin is not suitable for everyone.

Not recommended for severe psychiatric disorders, pregnancy, severe heart problems, or certain medications.

Suitable for people with sufficient mental stability and a willingness to introspect.

Practical questions

A full session usually takes six to eight hours.

Driving on the same day is advised against.

Frequent use reduces effects and limits processing time.

Comfortable clothing and basic necessities usually suffice.

Sessions versus ceremonies

Ceremonies often have a ritual or spiritual character.

Sessions can also be purely guided and practical.

Finally

A valuable psilocybin session is characterized by safety, trust, and space for a personal experience.

Not the intensity, but the personal meaning determines the quality.

Psilocybin opens up possibilities. What you do with it always remains individual.

A psilocybin journey can be structured in various ways, and this is precisely where confusion often arises. For one person, it means a ceremony; for another, a guided trip; and within a therapeutic context, it is viewed as psychedelic-assisted therapy. Although the substance is the same, the framework differs fundamentally. To provide a realistic and complete picture, it is useful to bring together the psychological, experiential, and biological perspectives.

Psilocybin: experience versus therapy

Many people know psilocybin from truffle ceremonies or sessions with a facilitator. In such a setting, the emphasis lies primarily on the experience itself: safety, tranquility, set and setting, and providing a stable presence. The facilitator typically does not intervene actively therapeutically, but monitors the environment and provides support where necessary.

Within psychedelic-assisted therapy, the focus shifts. Here, psilocybin is not viewed as an end in itself, but as a catalyst within a broader treatment trajectory. The experience forms part of psychological work in which preparation, therapeutic guidance, and integration play a central role. When traumatic memories, intense emotions, or physical release occur during the session, a therapist can apply techniques that align with the process, such as somatic interventions, EMDR principles, or IFS work.

The distinction is important because expectations are strongly influenced by the chosen framework. A ceremony is not the same as therapy, while both can be valuable depending on the nature of the request for help.

The intake and screening: foundation of safety

A thorough process begins with screening. This involves assessing mental and physical health, medication use, psychiatric history, stress regulation, and personal intentions. This process is not a formality, but an essential layer of safety.

Psilocybin is not suitable for everyone. Severe psychiatric disorders, certain medications, pregnancy, and specific cardiovascular risks can constitute contraindications. Proper screening prevents a session from taking place under circumstances where the experience could be destabilizing.

Preparation: set and setting in practice

The quality of a psilocybin experience is strongly determined by set and setting. Mental state, expectations, emotional load, and environmental factors often influence the course more than the exact dosage.

Preparation can range from practical alignment to in-depth therapeutic work. In a lighter form, this involves creating calm, formulating intentions, and minimizing external stimuli. In a therapeutic process, attention is also paid to recurring patterns, potential triggers, and nervous system regulation. Learning to recognize activation and developing grounding techniques often proves particularly valuable during the session.

Physical preparation also plays a role. Eating a light meal beforehand, comfortable clothing, and a free schedule afterward contribute to a stable process.

How does psilocybin work biologically?

After ingestion, psilocybin is converted into psilocin in the body, usually within fifteen to forty-five minutes. Psilocin is structurally similar to serotonin and binds to 5-HT2A receptors, among others. This mechanism is associated with changes in perception, cognition, and emotional processing.

A much-discussed effect is the temporary suppression of the default mode network. This network plays a role in self-reflection, identity perception, and repetitive thought patterns. Reduced activity is associated with greater mental flexibility, which can be subjectively experienced as a shift in perspective or a breaking of fixed patterns.

In addition, research into blood biomarkers suggests broader systemic effects. Studies report changes in inflammatory markers, stress hormones, and BDNF, among others. An increase in BDNF fits within models centering on neuroplasticity, the brain's ability to form new connections and reorganize existing networks.

Simultaneously, increases in cortisol and ACTH are observed, which is typically interpreted as a physiological response to the intensity of the experience. This emphasizes that psilocybin is not exclusively a psychological phenomenon, but an integral neurobiological event.

Hypotheses regarding broader effects, such as a possible influence on cellular aging processes, are being investigated but are currently speculative. Reduction of inflammation and long-term stress reduction provide theoretical leads, but direct clinical confirmation is still lacking.

The course of the session

Although every experience is unique, a session often follows a recognizable pattern. After the initial phase, in which physical sensations and subtle changes occur, a gradual shift in perception and thoughts emerges. The intensity usually peaks between one and a half and three hours after ingestion, followed by a gradual decline.

The subjective content varies greatly. Some experiences are calm and introspective, others emotional, insightful, or visually rich. Emotions may deepen, memories may surface, and physical sensations may intensify. This is not necessarily negative; intensity is often part of the processing.

It is important to note that there is no such thing as a “right” experience. The value of a session is not determined by visual effects or dramatic breakthroughs, but by the personal meaning and integration afterwards.

Difficult moments and psychological dynamics

Anxiety, confusion, or emotional intensity may occur. Resistance often amplifies such reactions, while acceptance and regulation usually have a stabilizing effect. Breathing, body awareness, and a safe setting play a crucial role in this.

Attempts to actively stop the experience are usually ineffective, which underscores why preparation and guidance are so important.

The role of guidance

Guidance can range from non-directive presence to active therapeutic intervention. In an experiential session, the emphasis is on safety and stability. In a therapeutic context, the facilitator can respond to psychological processes when functional.

Individual sessions offer maximum privacy and flexibility. Group sessions can provide a sense of connection and shared safety. The choice depends on personality, the nature of the problem, and preference.

Integration: where change is consolidated

The experience ends, but the process continues. Neuroplasticity models suggest that after psilocybin, a period of heightened receptiveness arises in which new insights and behavioral change can be anchored more easily.

Integration means translating experiences into daily life. Reflection, therapeutic debriefing, and practical application largely determine the sustainability of the effects. Some experience an afterglow, while others experience heightened sensitivity. Both reactions fit within normal processing dynamics.

Expectations and progress

Psilocybin therapy is currently in scientific development. Studies report significant reductions in depression and anxiety symptoms in specific populations, but individual outcomes vary. Not everyone experiences the same degree of improvement, and certain vulnerabilities can influence the effect.

Caution and realistic expectations therefore remain essential.

Finally

A psilocybin session is not a uniform experience, but an interaction between neurobiology, psychology, and context. Safety, preparation, and integration are the constant factors that determine how meaningful and stable the process unfolds.

Psilocybin opens possibilities for insight and change. What presents itself, and what someone does with it, always remains personal.

Psilocybin, the active ingredient of certain mushrooms, is attracting increasing attention as a potential treatment for treatment-resistant depression. Despite significant clinical interest, the underlying question remains the same: what happens biologically in the body, and how can these processes contribute to the antidepressant effect?

Researchers at the UMCG approached this question through a systematic literature review of changes in blood values after psilocybin intake. The focus was on biomarkers known to be relevant to depression.

What was investigated?

In the review, nine studies conducted in healthy subjects were analyzed. These studies investigated biomarkers, measurable biological parameters that provide insight into physiological processes that are often disrupted in depression.

The focus was on inflammatory activity, including CRP and IL-6, hormonal stress responses such as cortisol and ACTH, brain growth factors such as BDNF that play a role in neuroplasticity, and hormones associated with mood and social behavior, including oxytocin and prolactin.

Although most studies were small-scale and were not conducted in depressed patients, the systematic analysis provides a first overview of the biological changes that occur after psilocybin intake.

What changes in the blood?

The researchers found multiple consistent patterns.

Inflammatory markers such as interleukin-6 (IL-6), C-reactive protein (CRP), and eosinophils decreased. This suggests a possible anti-inflammatory effect, a relevant mechanism as depression is increasingly associated with low-grade chronic inflammatory processes.

Stress hormones such as cortisol and ACTH increased. This rise is generally interpreted as a physiological response to the intensity of the psychedelic experience, and not necessarily as a harmful effect.

In addition, an increase in BDNF was observed. BDNF plays a central role in neuroplasticity, the brain's ability to form new connections and reorganize existing networks. This mechanism is also seen with other fast-acting antidepressant interventions.

Furthermore, increases were found in oxytocin and prolactin, hormones involved in mood, social bonding, and emotional processing.

These findings are partially consistent with previous animal studies and suggest that psilocybin influences multiple biological systems involved in depression.

Neuroplasticity as a core mechanism

The increase in BDNF fits within a broader hypothesis in which neuroplasticity plays a central role. Depression is increasingly viewed as a condition in which brain networks function less flexibly.

Psilocybin appears to temporarily reduce the rigidity of these networks. At a functional level, reference is often made to the temporary suppression of the default mode network (DMN), a network involved in self-reflection and repetitive thought patterns. At a molecular level, changes in BDNF suggest a possible increased capacity for restructuring neural circuits.

This combination of functional and biological effects forms a plausible model for the observed antidepressant effects.

Inflammation and depression

The decrease in inflammatory markers is particularly relevant within modern models of depression. Chronic low-grade inflammation is associated with changes in neurotransmitter systems, stress regulation, and neuroplasticity.

The observed anti-inflammatory effects of psilocybin suggest that the drug may act on a mechanism on which classic antidepressants often have less direct effect.

This opens the door to a broader biological interpretation of psychedelic therapy.

Possible effects on cellular aging

In addition to inflammation and neuroplasticity, interest is growing in another domain: cellular aging.

Chronic stress and inflammation are associated with accelerated biological aging, including telomere shortening. Telomeres function as protective structures at the ends of chromosomes and play a role in cellular stability.

There is currently no robust clinical evidence that psilocybin directly increases telomerase activity. However, there are theoretical and indirect leads.

1. Reducing inflammatory activity can contribute to a more favorable cellular environment, as chronic inflammation is linked to accelerated telomere shortening.

2. Changes in stress regulation, including the long-term reduction of psychological stress after successful sessions, could indirectly influence processes associated with cellular aging.

3. Increased neuroplasticity and possible epigenetic changes constitute an area of research in which broader effects on cellular adaptation are being speculatively examined.

It is important to emphasize that these hypotheses largely stem from related research into stress, inflammation, and aging, and not from direct telomerase measurements in psilocybin users. Further studies are necessary to confirm or refute this link.

What does this mean in practice?

Although direct clinical applications are still limited, the results support several key insights.

The findings are consistent with the idea that psilocybin may have a biologically substantiated antidepressant effect. Additionally, they provide starting points for future research into biomarkers that can predict treatment response.

Biomarkers such as BDNF, CRP, and IL-6 may potentially play a role in better understanding individual treatment outcomes.

The results also reinforce the hypothesis that inflammation modulation may be a relevant mechanism of action.

Limits

Caution remains essential.

Most data are derived from small studies with healthy volunteers. Additionally, some biological changes may be related to the acute stress response associated with an intense psychedelic experience.

Furthermore, it primarily concerns short-term measurements. The stability and clinical relevance of these long-term effects have not yet been sufficiently investigated.

What is needed?

Future research should focus on clinical populations with depression, particularly people with treatment-resistant depression.

Larger, controlled studies with longer follow-up are necessary to determine the clinical significance of biomarker changes.

In addition, it is important to explicitly measure stress responses so that a distinction can be made between pharmacological effects and general physiological reactions.

Research into cellular aging markers, including telomere length and telomerase activity, constitutes a logical but still largely unexplored field.

Conclusion

This systematic review provides initial indications that psilocybin influences biological processes involved in depression, including inflammatory activity, neuroplasticity, and hormonal regulation.

This positions psilocybin as a promising candidate in depression research. Hypotheses regarding broader effects, such as a possible influence on cellular aging, are scientifically interesting but require substantial additional research.

Definitive conclusions depend on future studies in clinical populations, in which both psychological and biological outcomes are investigated in an integrated manner.
