Psilocybin isn't like a beer or a gummy you take at a party and just hope for the best. Well, people do that, but it’s usually why they end up staring at a blade of grass for six hours while questioning their entire existence in a way that feels more like a crisis than a breakthrough. If you're looking for a magic mushroom dose guide, you've probably realized that "one cap" is a measurement about as accurate as "a pinch of salt" in a chemistry lab. It’s useless.
The reality is that weight, species, and your own brain chemistry turn dosing into a bit of a moving target.
Back in the day, the legendary Terrence McKenna used to shout about the "heroic dose" of five dried grams in silent darkness. That’s cool for a philosopher, but for someone just trying to shake off some anxiety or see what the hype is about? It's overkill. Honestly, it's irresponsible. Most people aren't ready for their ego to be put through a paper shredder on a Tuesday night.
Why "Grams" Are Kinda Deceptive
Here is the thing no one tells you: a gram of Psilocybe cubensis—the most common species—is not always the same as another gram.

Potency varies wildly. One batch of Golden Teachers might be mild, while a batch of Penis Envy (yes, that’s the actual name) can be two or three times as strong. This is because of the concentration of psilocybin and psilocin within the fungal tissue. A study published by the Uricani group or researchers like Dr. Felix Blei have shown that even within the same flush of mushrooms, the alkaloid content can fluctuate by massive percentages.
Think of it like peppers. Sometimes a jalapeño is basically a bell pepper; sometimes it ruins your week.
The Microdose (0.1g – 0.3g)
This is the "sub-perceptual" zone. You aren't supposed to "trip." If the walls start breathing, you didn’t microdose; you just had a light breakfast.
People use this for flow states or to help with mild depression. Dr. James Fadiman, who basically wrote the book on this with The Psychedelic Explorer's Guide, suggests a "one day on, two days off" protocol. It keeps your tolerance from spiking. You might feel a little more focused. Maybe you’re slightly more patient with your annoying coworker. It’s subtle.
The Museum Dose (0.5g – 1.0g)
I call it this because you can actually go to a museum and look at art without forgetting how to use a door.

At 0.5g to 1.0g, colors start to pop. Everything looks a bit high-definition. You’ll feel a "body load"—that weird, tingly, slightly heavy sensation in your limbs. It’s a social dose. You’re talkative. You’re giggly. It’s great for a hike, but you might find it hard to focus on a complex movie plot. It's the "shallow end" of the pool.
The Moderate Trip (2.0g – 3.5g)
This is where the actual journey starts.
At two grams, the internal dialogue begins to shift. You might see geometric patterns when you close your eyes. When you hit the 3.5g mark—the classic "eighth" of an ounce—you are firmly in another dimension. This is the dose where people have "breakthroughs."
You’ll likely experience:
- Synesthesia: Hearing colors or seeing sounds.
- Time Dilation: Five minutes feels like an hour.
- Emotional Purge: You might cry about a tree. You might laugh until your ribs hurt. Often both.
Researchers at Johns Hopkins University, led by the late Dr. Roland Griffiths, often used doses roughly equivalent to 3.0g to 4.0g of dried mushrooms for their studies on end-of-life anxiety. They found that this "high dose" range was the sweet spot for mystical experiences that actually changed people's lives for the better. But they had guides. They had eye masks. They had a playlist. Don't do this at a music festival if you've never done it before.
The Heroic Dose (5.0g+)
Don't. Just... don't, unless you are very experienced.
This is total ego dissolution. You might forget your name. You might forget you are a human. You might meet "entities" or feel like you’ve dissolved into the fabric of the universe. It’s profound, sure, but it’s also physically and mentally exhausting. The recovery time—the "integration"—for a 5-gram trip can take weeks.
The Variables You Can't Ignore
Your stomach matters. If you eat a massive steak dinner and then take two grams, it might take two hours to kick in, or it might not hit at all. Take them on a light stomach.
Then there is the "Lemon Tek." People swear by soaking ground-up mushrooms in lemon juice for 20 minutes before drinking it. The theory is that the citric acid begins the conversion of psilocybin into psilocin (the stuff that actually makes you trip) so your stomach doesn't have to do the work. It makes the come-up much faster and more intense. It also shortens the trip. If a normal trip is 6 hours, a Lemon Tek might be 4, but it’ll be a wild 4 hours.
Set and Setting are more important than the dose itself.
If you are in a bad headspace or a chaotic environment, a 1g dose can feel scarier than a 3g dose in a safe, comfortable room with a trusted friend.
Safety and Interaction
It is vital to talk about SSRIs.
If you are on antidepressants like Prozac or Zoloft, mushrooms might not work for you. These medications occupy the same serotonin receptors (5-HT2A) that psilocybin targets. Some people find they need double the dose to feel anything; others find it blunts the experience entirely. More importantly, there is a theoretical risk of serotonin syndrome, though it's rarely reported with psilocybin alone. Always check with a medical professional who understands psychedelics before mixing substances.
Also, stay hydrated. It sounds simple, but you’ll forget.
How to Actually Start
If you are a beginner, the best way to use this magic mushroom dose guide is to start low. You can always add, but you can't subtract. Once the rocket has launched, you're on it until it lands.
- Start with 1 gram. See how your body reacts to the "body load."
- Wait at least two weeks between sessions. Tolerance builds instantly. If you trip on Saturday, taking the same amount on Sunday will do almost nothing.
- Get a scale. Do not "eyeball" it. Mushrooms vary in density. A small, dense mushroom can weigh way more than a large, airy one. A cheap $15 milligram scale from the internet will save you from a very bad night.
- Write it down. Keep a log. "Batch A, 1.5g, felt great, bit of nausea." It helps you find your personal threshold.
The goal isn't to get as high as possible. The goal is to get what you need from the experience. Sometimes, that means a tiny bit of color and a lot of laughter. Other times, it's a deep dive into your own psyche. Respect the fungus, and it’ll usually respect you back.
Move forward by choosing your environment first. Find a space where you won't be interrupted for at least eight hours. Turn your phone on "Do Not Disturb"—nothing ruins a trip like an unexpected call from your landlord or a work email. Have a "trip sitter" if it's your first time going over two grams; just having someone in the other room who is sober can keep you grounded if things get intense. Focus on the breath, stay curious, and let the experience happen rather than trying to control it.
