How to Calculate Your Shroom Dose

Dosing raw shrooms precisely is an important factor since it may make the difference between a fun trip and a bad one. Now, there's no reason to be scared we will explain everything you need to know on how to calculate your shroom dose!

Calculating your shroom dosage can be tricky, especially for beginners or those who are not using products like shroom edibles, which have already pre-defined doses and are easy to use.

Shroom Dosage Chart

Precise dosage calculations are extremely hard due to multiple different internal factors such as weight, age, gender, and individual body chemistry. However, for the sake of this guide, we will focus solely on weight as it appears to be the biggest factor that affects the dose.

How to Calculate Your Shroom Dose


Microdosing is taking a very small dose of a psychedelic substance that will not produce any detectable psychedelic effects. This dosage is frequently referred to as sub-perceptual meaning that it doesn’t change sensory perceptions like visuals or distortions in time and space.

A microdose typically consists of one-tenth to one-twentieth of the normal dosage required to have psychedelic effects. A microdose, for instance, would normally be between 0.1 and 0.3 grams if the usual dosage of dried magic mushrooms is between 1 and 3 grams.

People who microdose often experience:

  • Better mood
  • Creative thinking
  • Increased energy levels

Low Dose

A low dosage of shrooms is one where you begin to notice some psychedelic effects, though there isn’t an exact threshold separating a microdose from a low dose. Nonetheless, several indicators, such as slight perceptual changes, aid in distinguishing between the two.

A low dose of shrooms depends on the particular mushroom species and their potency. However, a general rule of thumb is that a low dose ranges from 0.3 to 1 gram of dried Psilocybe cubensis.

At a low dose you might experience:

  • Brighter Colors
  • Slight body high
  • Feeling euphoric

Moderate Dose

A moderate dose of shrooms is where more intense psychedelic effects come in place. People who use shrooms recreationally usually stick with a moderate dose as it produces “trippy” effects like notable visual hallucinations, laughter, and crossing of the senses.

Typically, a moderate dose ranges from 1 to 3 grams of dried shrooms. However, inexperienced psychonauts should stick with with lower dose range.

Moderate dose can induce feelings of:

  • Hallucinations
  • Introspection
  • Euphoria
  • Gratitude

High Dose

A high dose of shrooms can have significant effects, including major changes in mood, perception, mental process, and thought patterns. Although the dose is just slightly higher compared to moderate, the effects are significantly stronger.

A high dose of shroom ranges between 3 and 4 grams of dried shrooms. Be careful with higher doses, they can easily become overwhelming even to the most experienced psychonauts.

At this dosage people experience:

  • Strong Hallucinations
  • Visions
  • Powerful Insights
  • Feeling of dissociation from the body

Heroic Dose

A heroic dose offers a distinct experience compared to other described dosages. At this level, it’s most likely to have a mystical experience and ego death, which is an unusual phenomenon that commonly occurs at high doses of psychedelics.

Depending on the person’s tolerance, a heroic dose is considered to be everything above 5 grams of dried shrooms. At this dosage having a tripsitter is a must.

Heroic dose is well-know for causing:

  • Ego dissolution
  • Sense of interconnectedness
  • Timelessness
  • Profound knowledge

Shrooms and Body Weight

An ideal psilocybin dose is determined in large part by body weight. Numerous studies recommend dosages between 20 and 30 milligrams for every 70 kg (154 lbs) of body weight.

According to a 2021 study, dried mushrooms normally have a psilocybin content of 0.1–0.2%, but this can vary greatly. It is impossible to determine the precise psilocybin content without specialized equipment. According to the review, around 10–50 milligrams of psilocybin are equivalent to 10–50 grams of fresh mushrooms or 1–5 grams of dried mushrooms.

However, these guidelines hinge greatly on the mushroom species involved. Contrary to popular belief, there isn’t just one type of magic mushroom; over 180 species have been identified. While the general effects of each species are similar, differences in potency can significantly impact the psychedelic experience.

How to Weight Shrooms Correctly

A precise scale is essential for accurate measures. Although many psychonauts may own milligram scales for measuring powders and plant substances, a traditional scale calibrated to tenths or hundredths of a gram will serve perfectly well for shrooms and other mushroom products.

How to Calculate Your Shroom Dose

Here’s a step by step guide on how to effectively use a digital scale:

  1. Place the scale on a level surface making sure that it doesn’t move around and power it on.
  2. Place a tray or a container onto the scale’s weighing surface and press the “Tare” or “Zero” button. This action zeroes the scale with the tray, ensuring it doesn’t account for the tray’s weight during measurements.
  3. Add shrooms on the scale one by one until the scale displays the desired dosage.
  4. If you accidentally add too much simply remove smaller pieces first, or even break the shrooms into smaller pieces to match your desired dosage.

Final Word

Setting up the perfect setting and state of mind is important, yet going into a magic mushroom trip unaware of the dose might result in unanticipated levels of intensity. It’s important to know the dose and make sure it’s measured correctly whether you’re consuming mushrooms at a retreat or the comfort of your own home. It’s also essential to be aware of the particular variety of mushrooms you plan to consume. To have the desired effect, it’s best to go with the lower end of the dose range if it’s a very powerful mushroom species.

Hopefully, our guide helped you understand the different dosages and how to calculate your shroom dose for your next trip. Make sure to stay mindful, in a positive set and setting to have the most impactful experience. Happy tripping!
