Mushroom Dosage Calculator

More people are becoming interested in magic mushrooms as research continues to reveal the potential benefits of psilocybin. One common question is how much is needed to potentiate a meaningful experience while minimizing the risk of adverse effects.

There is no straightforward answer as mushrooms affect everyone differently, and the optimal dose depends on numerous factors. This article explores the relationship between mushroom dosage and body weight, the type of mushrooms, and various other considerations.

While our magic mushroom dosage calculator provides a rough estimate, there are many other things to consider. Read on for a summary of the latest research on mushroom and psilocybin dosing and other influential factors.

Dosage and Body Weight

Bodyweight is often considered one of the most critical factors in determining an appropriate psilocybin dosage. Most trials involve doses of 20–30mg per 70kg of weight, with doses over 25mg considered relatively high.

According to a 2012 study, doses as low as 5mg/70kg produced subjective effects in some participants. Although higher doses correlated more strongly with lasting positive outcomes, they also increased the risk of adverse reactions, including anxiety and fear.

Other research suggests that doses of 45–315mcg/kg may be effective, with the risk of adverse reactions increasing at doses over 420mcg/kg. However, while bodyweight appears to play a role in dosing, it may not be as crucial as initially thought.

A 2021 publication analyzed data from ten previous studies. It compared participants who took a weight-adjusted dose of 20 or 30mg of psilocybin per 70kg with those who took a fixed amount of approximately 25mg.

The results suggested that there was no significant difference in subjective effects between the weight-adjusted and fixed doses. For example, there were no additional effects in heavier or lighter participants who took similar amounts of psilocybin.

Dosage and Type of Mushroom

While there is plenty of research into psilocybin dosage, mushrooms are another matter. Dosing is far more complex because different mushrooms produce varying amounts of psilocybin. Some also contain other psychoactive compounds, such as psilocin and baeocystin.

According to a 2021 review, dried mushrooms usually contain approximately 0.1–0.2% psilocybin, although this figure can vary greatly. Without highly specialized extraction and chromatography equipment, it is impossible to know for sure.

The review suggests that 10–50g of fresh mushrooms or 1–5g of dried mushrooms is roughly equivalent to 10–50mg of psilocybin. This aligns with information from the Oregon Psilocybin Advisory Board Rapid Evidence Review and Recommendations. The latter publication suggests that 1–4g of dried mushrooms constitutes a dose.

However, these figures are highly dependent on the type of mushroom involved. There are many different psilocybin mushrooms, and some are more potent than others.

For example, certain Psilocybe species, including P. azurescens and P. cyanescens, are considered more potent than P. cubensis or P. semilanceata. Anecdotal reports also suggest that, in general, magic mushrooms are more potent than magic truffles.

Moreover, because they are a natural product, the amount of psilocybin in each mushroom or truffle can vary significantly. This is even true between different specimens from the same flush, presenting a real challenge when calculating how many mushrooms to take.

Other Considerations

Another 2021 publication analyzed data from 17 studies with psilocybin doses ranging from 45–600mcg/kg. It highlighted the importance of set and setting and how they alter the nature of psychedelic experiences.

The ‘set’ included factors such as the participants’ personality, expectations, intentions, previous use, and degree of preparation. Meanwhile, the ‘setting’ referred to the physical, social, and cultural environment in which psilocybin was ingested.

Researchers have concluded that dosage alone does not explain the variation in subjective effects reported by psilocybin users.

It found that current mood, intention, and whether psychological distress occurred before use had a significant impact. It also suggested that personality traits such as extraversion were frequently associated with positive effects, whereas neuroticism increased the occurrence of challenging experiences.

The age of the participants also seemed to have some influence, with younger participants more likely to have challenging experiences. While dosage was a critical consideration, the authors concluded that it did not explain the considerable variation in subjective effects reported.

Magic Mushroom Dosing and Safety

It is widely accepted that magic mushrooms have a low harm potential compared with other psychoactive drugs. Side effects tend to be mild and transient, and there is little risk of overdose.

However, there is always a chance that an individual could have a challenging experience, colloquially known as a bad trip. While this is not directly harmful, it can be extremely distressing and may lead to dangerous behavior and physical injury.

Furthermore, magic mushrooms are not safe for everyone. They can cause temporary increases in heart rate and blood pressure, potentially making them unsuitable for people with cardiovascular conditions.

There have also been reports of long-term psychological problems following psilocybin use, especially in people predisposed to mental health conditions. Participants of clinical trials undergo thorough medical screening before dosing to minimize this risk.

Research also takes place under closely controlled conditions, with adequate preparation and supervision. Therefore, taking high doses in such settings is considered safe, whereas the real world poses more dangers.

While our mushroom dosage calculator can provide approximate dosage guidelines, it is not a substitute for proper medical screening. We recommend consulting a knowledgeable healthcare professional for further advice.
