Psychedelic mushrooms, commonly known as magic mushrooms, belong to the Psilocybe genus and are renowned for their psilocybin content, a compound that induces psychedelic experiences. Understanding the appropriate dosage is crucial for a safe and meaningful experience. This comprehensive Shroom Dosage Guide will delve into the psilocybin content of common Psilocybe species and provide insights on how to determine the right dosage when using dried magic mushrooms or psilocybin products.
Understanding the Active Compounds in Magic Mushrooms
It’s a common misconception that psilocybin is the direct psychoactive component in magic mushrooms. In reality, psilocybin acts as a prodrug. Upon ingestion, your body metabolizes psilocybin into psilocin. Psilocin is the actual active compound responsible for the psychedelic effects. This transformation occurs because psilocin’s molecular structure closely resembles serotonin, a neurotransmitter in the brain, allowing it to interact with serotonin receptors and produce altered states of consciousness.
Decoding Psilocybin Content in Magic Mushrooms

Similar to cannabis, the potency of magic mushrooms can vary significantly. Even mushrooms from the same species and harvest can exhibit different levels of psilocybin. The only definitive way to ascertain the exact potency of a mushroom is through laboratory testing.
Given the current legal landscape in many regions, lab testing for magic mushrooms is not widely accessible. However, existing research provides valuable data on the psilocybin concentration in prevalent Psilocybe mushroom species, which we can utilize to develop informed shroom dosage guidelines.
Psilocybe cubensis is the most frequently encountered magic mushroom species. Research indicates that Psilocybe cubensis mushrooms typically contain around 0.5% to 1.0% total psilocin, averaging approximately 0.7% by weight. This 0.7% total psilocin translates to roughly 1% psilocybin. It’s vital to remember that psilocybin levels fluctuate considerably, not only between different species but also within the same species.
Exploring the Effects of Varying Psilocybin Dosages
Assuming your magic mushrooms contain 1% psilocybin, let’s explore how different weights of mushroom consumption can lead to weak, medium, and strong effects. For each dosage level, we will estimate the psilocybin content, describe the anticipated effects based on reports from experienced users, and reference findings from clinical trials involving humans.
Psilocybin dosage chart for different experience levels
Low Dose: 1 Gram
A one-gram dose of magic mushrooms is generally considered a mild dose that still produces noticeable effects. It is important to distinguish this from a microdose. (For detailed information on microdosing, refer to this guide on microdosing psilocybin magic mushrooms.) At this level, you are unlikely to experience intense psychedelic visuals or a significant departure from reality. Instead, expect to feel euphoria and heightened sensory perception, such as more vibrant colors. With a 1% psilocybin content, a one-gram dose contains approximately 10 milligrams (mg) of psilocybin. It’s crucial to note that this is a low, perceptible dose, not a microdose.
Medium Dose: 1.75 Grams
Consuming 1.75 grams of magic mushrooms, which is half of a common eighth-ounce quantity, translates to roughly 17.5 mg of total psilocybin. At this medium dose, you are likely to encounter genuine psychedelic effects. These can include both open and closed-eye visuals, synesthesia (a blending of senses), and a more pronounced euphoria. However, you may not fully lose your sense of self or reach the profound, mind-altering states often reported with higher doses.
High Dose: 3.5 Grams (One-Eighth Ounce)
A standard eighth-ounce, or 3.5 grams of dried mushrooms, contains about 35 mg of psilocybin. This dose is considered a high dose and will likely induce a full-blown psychedelic experience. Expect significant perceptual and cognitive distortions. Holding a conversation or accurately perceiving your surroundings may become challenging, particularly during peak experiences, which often occur in waves. While each trip is unique, a 3.5-gram dose is almost guaranteed to be a memorable and impactful experience. It is strongly advised to only take a high dose in a secure and supervised environment.
Ultra-High Dose: 5 Grams
The renowned psychonaut Terence McKenna famously advocated for the “heroic dose” – 5 dried grams of mushrooms consumed in silent darkness – as the optimal way to fully explore the depths of the mushroom experience. At a 1% psilocybin concentration, 5 grams will contain approximately 50 mg of psilocybin. At this ultra-high dose, the best course of action is to find a comfortable position and surrender to the experience. Your usual sense of self will likely dissolve as the effects intensify. The experience will likely be intense, possibly strange, and hard to articulate. Doses of this magnitude are rare. Even experienced psychedelic users seldom venture this high. It is highly discouraged to attempt a dose even remotely close to this without substantial prior experience and an extremely safe, comfortable setting with a trip sitter.
Insights from Clinical Trials
How do these dosage guidelines align with findings from controlled clinical trials involving humans? Pioneering psilocybin research at institutions like Johns Hopkins University has administered controlled psilocybin doses to participants. These studies have explored a range of dosages and generally found that higher doses frequently induced what researchers termed a “mystical-type experience.” This term is the formal research equivalent of a “full-blown psychedelic experience.” The psilocybin doses used to reliably trigger such experiences typically ranged from 20-30 mg, falling between the medium and high dose categories in our shroom dosage guide. This suggests that a full eighth-ounce (3.5 grams) of dried P. cubensis is likely to contain a higher psilocybin content than doses used to consistently elicit mystical-type experiences in controlled scientific settings.
Safe Practices for Taking Magic Mushrooms
When venturing into the realm of psychoactive substances, the mantra “start low, go slow” is paramount. Beyond microdosing, begin with no more than one gram of dried mushrooms, equivalent to about 10 mg of psilocybin. You can gradually increase your dosage in increments of approximately 0.25 grams, waiting for at least 25 minutes between increases to gauge the effects. Only consider experimenting with higher doses once you are completely comfortable with lower dosages. Furthermore, it is crucial to consume psilocybin in a safe and comfortable environment, ideally with a trusted and sober individual present to provide support. In some research settings, professional support is provided to participants, as was the protocol in the Johns Hopkins studies. The nature of your experience with psilocybin and other psychedelics is profoundly influenced by your mental and emotional state, physical condition, and the surrounding environment – collectively known as “set and setting.”
Once you progress into the “medium dose” range and beyond, it becomes increasingly important to be aware of the profound nature of these experiences. Remember that psychedelic experiences can be transformative. Participants in the Johns Hopkins studies frequently described their 20-30 mg psilocybin experiences as being among the most significant events of their lives, often comparing their impact to life-altering events like the birth of a child.
Mushroom Caps vs. Stems: Potency Variations
Comparison of psilocin content in caps versus stems of Psilocybe cubensis mushrooms. Bars represent average total psilocin from caps and stems, with vertical lines indicating standard deviation.
Anecdotal reports often suggest that either the caps or stems of magic mushrooms are more potent. Limited scientific data exists on this topic. Analyzing data from study 2 and study 3, it appears that P. cubensis caps tend to have a slightly higher average total psilocin content compared to stems. However, there is considerable variation between samples and overlap in psilocin levels between caps and stems, making this an unreliable determinant of potency. Further research is needed to draw definitive conclusions.
Optimal Storage for Maintaining Magic Mushroom Potency
A 2020 study investigated psilocybin degradation over 15 months of storage under different temperature and lighting conditions. The study concluded that psilocybin content is best preserved when mushrooms are stored at room temperature in dark conditions. Storing mushrooms at very cold temperatures led to the most significant psilocybin degradation. Regardless of storage conditions, psilocybin will degrade over time, with noticeable losses potentially occurring within just one month. For maximum potency, fresh mushrooms are always the best choice.
