This manual is for educational and harm reduction purposes. Psilocybin is a potent substance. Self-administration, especially in high doses (Phase 3), involves psychological risks. Individuals with a personal or family history of schizophrenia, bipolar disorder, or psychosis should not use psychedelics.
Individuals with a history of cardiovascular issues — uncontrolled hypertension, arrhythmias, or heart disease — should also avoid use without medical supervision. Psilocybin causes a temporary increase in blood pressure and heart rate during the experience.
Mixing with psychiatric medications requires extra caution for two distinct reasons: SSRIs tend to reduce or completely nullify the effects of psilocybin (due to a downregulation mechanism of 5-HT2A receptors); while MAOIs and Lithium can cause severe and potentially dangerous interactions. Consult a professional before any combined use.
PART 1: Scientific Foundation - What happens in the brain?
To extract real results, you need to abandon the mystical idea and understand the machine. Psilocybin is not a "magic cure"; it is a chemical catalyst that creates a window of neurological opportunity.
- Basic Chemistry: The mushroom (Psilocybe cubensis) contains psilocybin, which is converted into psilocin by enzymes present mainly in the small intestine, blood, and liver. It is psilocin that crosses the blood-brain barrier (the selective membrane that protects the central nervous system) and binds to serotonin receptors (specifically 5-HT2A) in your brain.
- Ego Shutdown (DMN Inhibition): The human brain has a network called the Default Mode Network (DMN). It is the "manager" of your mind. It creates your sense of "Self", your worries about the future, rumination over the past, and the repetitive thought patterns that feed depression and anxiety. Psilocin drastically reduces blood flow and activity in the DMN. "The manager leaves the room".
- Increased Global Connectivity: With the DMN silenced, areas of the brain that do not normally communicate begin to exchange information (synesthesia, accessing repressed memories under new perspectives).
- The Window of Neuroplasticity: After the session, the brain experiences an increase in the production of BDNF (Brain-Derived Neurotrophic Factor), a protein that acts as "fertilizer" for neurons. For about 14 to 30 days after the experience, your brain becomes more malleable (based on results from pre-clinical studies). It is much easier to break old habits and install new behaviors during this window.
Institutions like Johns Hopkins University and Imperial College London have already demonstrated that this mechanism is highly effective in treating treatment-resistant depression, existential anxiety in terminal patients, and chemical dependency (alcohol and tobacco).
PART 2: Logistics and “Set & Setting”
Before getting into the dosage protocol, the infrastructure must be flawless. The environment dictates the experience.
- The Tolerance Rule: This protocol requires an interval of 15 to 30 days between each session. Less than that, chemical tolerance nullifies the effect of the next dose.
- Dose Preparation: To prevent one individual mushroom from being much stronger than another, mix them. You can grind dehydrated mushrooms from the same batch in a blender until they become powder, or simply chop them as finely as possible with clean scissors. Weigh the exact portion for each session.
- Body Weight: The doses in this protocol are general references. Weight can influence the intensity of the experience — a 3g dose may affect a 60kg person differently than a 100kg person. If you are on the extremes (under 60kg or over 90kg), consider adjusting the doses slightly lower or higher within the indicated ranges for each phase.
- The Set (Mental State): In the days prior, avoid bad news, unnecessary stress, and alcohol. Define a clear intention (e.g., "I want to understand the root of my anxiety" instead of just "I want to see what happens").
- The Setting (Environment): A safe, comfortable place where you will not be interrupted for at least 6 hours. The more familiar, the better. Put your phone in airplane mode.
- Accessories: Eye mask (essential), comfortable headphones, and a blanket or duvet (the body feels very cold during the chemical takeoff).
- Music: Music can carry the experience. A suggestion is to use instrumental clinical playlists (search for Johns Hopkins Psilocybin Playlist on Spotify). However, listening to music is not mandatory and, if you feel like it at any point, you can turn it off.
- The Most Important Thing: Be comfortable and follow your instincts, but without deviating from the inner focus (keep the eye mask on whenever possible).
Forms of Ingestion
The mushroom's cell wall is made of chitin, a hard fiber that the stomach has some difficulty breaking down. In some people, this can cause mild discomfort or nausea in the early stages of the experience, although many people feel absolutely no nausea. Since chewing dry mushrooms has an earthy taste that not everyone tolerates, you can use one of these practical methods to ease ingestion and minimize any chance of discomfort:
- Lemon Tek (Citric Acid): Place the chopped or powdered mushroom in a cup and cover it with freshly squeezed pure lemon juice mixed with a little water. Let it sit for 15 to 20 minutes (stirring occasionally). The citric acid "pre-digests" the chitin. Advantage: Greatly reduces the chance of potential nausea and accelerates the onset. Drink it all at once (liquid and mushrooms).
- Ginger Tea: Boil water, turn off the heat and wait 1 minute (boiling water destroys the active substance). Add the chopped/powdered mushroom and a few slices of fresh ginger. Let it steep for 15 minutes. Strain the liquid and throw the mushroom mass away, drinking only the tea. Advantage: The psilocybin will extract into the water, ginger is a natural antiemetic (cuts potential nausea), and you avoid digesting the hard mushroom fiber.
- Light Foods (Yogurt or Banana): Mix the chopped mushroom with something pasty that you like, such as plain yogurt or peanut butter, or put it inside a piece of banana. This completely masks the texture and taste. Warning: Avoid mixing with pure cow's milk or heavy/greasy foods, as slow digestion can cause lethargy and physical discomfort.
PART 3: The Session Timeline
(What to expect)
Psilocybin has a predictable biological clock. Knowing this map of time prevents you from panicking, thinking the experience "will never end" or that a strange sensation is a sign that something went wrong.
Attention: The intensity of each stage below depends on the dose. In Phase 1 (1g), you will only feel the takeoff and a light plateau, without losing touch with reality. The map below describes the complete and deep journey of a Macrodose (Phase 3).
What you feel: Your body is breaking down the substance. You may start yawning a lot, feel cold or hot, your hands may sweat, and it's very common to feel mild nausea in the stomach. Anxiety will hit because you know the effect is about to begin.
Your task: Step away from phone screens. Focus on breathing. Remember that the initial discomfort is just your body processing the chemistry. It will pass.
What you feel: The substance reaches the brain. The perception of the environment changes and your survival instinct (the ego) will try to fight against this loss of control. This is where fear or the urge to "make it stop" usually appears. Your chest may feel tight.
Your task: Put on your eye mask, lie down, adjust your headphones, and do not fight. Surrender to the discomfort. It passes quickly if you stop resisting.
What you feel: The deep dive. Your sense of time will completely disappear (1 minute can feel like 1 hour). This is where immersive closed-eye visions, healing tears, access to memories, or a sense of absolute peace occur.
Your task: Keep your eyes closed. Just observe what the mind shows you and let it happen.
What you feel: The effect begins to subside, but it doesn't vanish all at once; it comes in "waves". You take off the mask, feel completely sober and normal, and 10 minutes later perception distorts again and you return to the trip.
Your task: Don't think it ended too early, nor get scared by the return of the effects. Drink water and welcome the waves.
What you feel: Visual alterations cease completely. You will feel physically exhausted, as if you ran a mental marathon, but you will likely feel immense peace and clarity.
Your task: Eat something light (fruit), rest, and begin your integration process.
PART 4: “Protocol 1, 2, 3”
This protocol was designed to bypass the ego's "fight or flight" biological mechanism. "We approach the door" gradually so that the mind surrenders voluntarily in the final phase.
Before advancing from one phase to the next, run this check: was the previous experience emotionally processed? Can you look at it without significant residual anxiety? If the answer is no, repeat the same dose in the next session before scaling up. The protocol is a suggested progression, not an obligation. Going slowly is always the smartest choice.
Phase 1 - Dose: 1g to 1.5g
(Proof of Concept)
- Objective: Break the stigma and fear of the substance. Map the physiological terrain.
- The Experience: You will not lose control of who you are. The effects will be primarily physical (yawning, some laughter, feeling cold/hot, perhaps mild nausea) and a soft alteration in the perception of colors and music.
- Your role: Focus solely on relaxing the body. Understand that if your stomach gets upset, it is normal and will pass. Success here is ending the session thinking: "Ok, that wasn't as scary as I was told".
Phase 2 - Dose: 2g to 2.5g
(The Shallow Dive and Navigation)
- Interval: at least 15 days after Phase 1.
- Objective: Begin accessing subconscious emotional content while still maintaining an anchor to reality.
- The Experience: Visible geometric patterns with eyes closed. Emotions (crying, laughter) may arise out of nowhere. The sense of time begins to distort. If you take off the mask, you still recognize the room, but reality is already quite altered.
- Your role: Practice the technique of "non-resistance". If a difficult emotion arises, the command is not to try to stop it, but rather to investigate. Ask yourself: "What is this trying to show me?".
Phase 3 - Dose: 3g to 3.5g
(The Macrodose and Dissolution)
- Interval: at least 15 days after Phase 2.
- Objective: DMN shutdown, ego dissolution experience for deep restructuring.
- Specific Preparation: This phase requires more careful preparation than the previous ones. In the 3 days before the session, reduce intense stimuli — social media, news, alcohol, and emotionally draining conversations. Write your intention on paper, don't just think about it. If you have a trusted person (even if they are not present at the session), let them know you will be doing the experience that day. Knowing that someone knows where you are creates a real psychological anchor of safety.
- The Experience: Immersion is total. Emotionally overwhelming. At certain points, you may forget you took a substance or have the sensation of dying or being reborn. It is in this type of deep experience that many participants report some of their most significant psychological insights.
Good to know: research from Johns Hopkins University shows that the most difficult experiences — the ones that seem unbearable in the moment — frequently generate the greatest therapeutic benefits months later. A challenging experience is not a sign that something went wrong. It is almost always a sign that something very important is being processed.
- Your role: Absolute surrender. The only rule in this phase is: "Whatever appears, look at it and keep moving forward". Trust the substance. Trust that your body is safe lying in bed.
Note: An important clarification about so-called "ego dissolution". In some people, doses in the 3g to 3.5g range can already produce a significant reduction in the habitual sense of identity — moments when the mental narrative of "who I am" temporarily weakens and experience is perceived with fewer cognitive filters. However, more complete states of dissolution are most frequently associated with higher doses, traditionally closer to 5g of dried mushrooms. Even so, modern clinical studies indicate that the therapeutic benefits of psilocybin do not necessarily depend on a total dissolution of the ego. Lasting changes in mood, perspective, and behavior often arise simply from emotionally significant experiences, deep psychological insights, and increased cognitive flexibility during the session.
PART 5: Integration Engineering
(Post-Session Tactical Execution)
The experience shows the door; integration is you walking through it in daily life. Without it, the session was just "recreational tourism".
1. Landing
(24h to 48h post-session)
- The brain is fatigued. Eat well, sleep, drink plenty of water.
- Golden Rule: No drastic decisions. Do not quit your job, do not end your marriage, and do not send impulsive messages based on the trip's "epiphanies". Let the dust settle for at least a week.
- Data Recording: Record a long audio on your phone just "venting" everything you remember from the experience. Don't try to organize it yet, just record it. Memories fade fast, like a dream.
2. Unpacking
(Week 1 and 2)
Sit down with a notebook (or your facilitator) and translate the experience. Use questions like these:
- What was the most uncomfortable feeling of the experience? What does it look like in your real life?
- Did the substance show you any lies you have been telling yourself lately?
- What did the experience ask you to release (let go of)?
- If the experience had a central theme or a single sentence of advice, what would it be?
3. Action Plan and Success Metrics
(Choosing Focus)
Use the neuroplasticity window to force behavioral change. Choose one of the metrics below to focus on for the next month:
- Option A: Tracking Micro-Habits (Ideal for depressive symptoms/procrastination):
Take the biggest insight from the trip and turn it into an action that takes just a few minutes.
Insight: "Nature heals me, technology makes me sick." -> Action: "I will stand in the sun for 10 minutes without my phone right after waking up." Track this on a calendar. - Option B: Trigger Journal (Ideal for anxiety/addiction):
The substance showed you your triggers. When the urge to smoke/drink or the anxiety attack comes in the following weeks, write down: Day, Time, and exactly what feeling arose 5 minutes before the urge appeared. You will begin to see the pattern that psilocybin pointed out. - Option C: Simple Mood Scale (Overview):
Every night, give a score from 1 to 10 for three things: Anxiety Level, Sleep Quality, and Feeling of Connection with others. After 30 days, compare the average with before the therapy.
CONCLUSION
Psilocybin is quite possibly one of the most potent tools in modern psychiatry for dismantling problematic mental narratives. However, the 3-phase protocol and the effort of integration serve to remind us of an undeniable truth: the mushroom performs the surgery, but the physical therapy is entirely your responsibility. Respect the substance, respect the intervals, and use the hard work of integration to solidify the version of yourself you found in there.
Scientific Foundation and Clinical Evidence
Over the last two decades, scientific interest in psilocybin has grown significantly within psychiatry and neuroscience. Research conducted by institutions such as the Johns Hopkins Center for Psychedelic and Consciousness Research and the Imperial College Centre for Psychedelic Research has investigated the therapeutic potential of the substance in controlled clinical settings.
Clinical trials conducted at these institutions observed relevant and lasting reductions in symptoms of treatment-resistant depression, anxiety associated with life-threatening illnesses, and certain types of chemical dependency. In many participants, a single session with psilocybin, when combined with adequate psychological preparation and subsequent integration, produced noticeable changes in mood, relationship with negative thoughts, and how difficult emotional experiences are processed.
Another consistent finding in these studies is that the subjective intensity of the experience — especially when accompanied by feelings of personal meaning or expanded self-perception — tends to correlate with longer-lasting therapeutic outcomes. This suggests that part of psilocybin's effect is less related to an isolated pharmacological mechanism and more to the type of psychological experience it enables when it occurs in a safe and structured context.
For this reason, in current clinical protocols, the substance is treated as a catalyst for a therapeutic process, not as an isolated treatment. Psychological preparation, support during the experience, and structured integration in the following weeks are considered essential components to transform the experience into lasting psychological change.
Limitations of Current Knowledge
Despite promising results, scientific research on psilocybin is still expanding, and several questions remain under investigation. The majority of clinical studies conducted so far involve relatively small samples of participants and occur in highly controlled environments, with rigorous psychological screening and specialized professional follow-up.
This means that the results observed in these contexts do not automatically translate to all types of use or all user profiles. Factors such as psychological history, life context, the environment of the experience, and the quality of the integration process can deeply influence perceived effects.
Furthermore, there is still no definitive scientific consensus on aspects such as optimal session frequency, most effective therapeutic dosages for different conditions, or the exact duration of the neurobiological changes associated with the psychedelic experience.
For these reasons, current scientific literature treats psilocybin as a promising tool under investigation — not as a universal solution. Responsible use requires respect for the substance's potency, attention to contraindications, and an understanding that the therapeutic value of the experience depends largely on the psychological work done before and after the session.
