Let’s be real for a second. If you’re asking how much shrooms should i take, you’ve probably realized that "winging it" is a terrible idea when it comes to psilocybin. It’s not like beer. You don't just "have a few" and see how it goes because, by the time the mushrooms actually kick in, you’re already buckled into the rollercoaster. There is no off-switch.
Mushrooms are unpredictable. Honestly, that’s the first thing any researcher or seasoned mycologist will tell you. You could have two dried grams of Psilocybe cubensis from one batch that feel like a gentle walk in the park, while two grams from another harvest might send you straight into a geometric void where time doesn't exist. It’s wild.

We have to talk about dosage in terms of weight—specifically dry weight—but also in terms of your own biology, your setting, and what you’re actually trying to achieve. Are you looking to sharpen your focus at work, or are you trying to talk to the universe? The answer changes the "how much" significantly.
The Spectrum of the Psilocybin Experience
Most people divide doses into four or five buckets. It’s not a perfect science, mostly because your metabolism and the specific strain (like Golden Teachers versus the much stronger Penis Envy) play huge roles.
First, there’s the microdose. We’re talking 0.1 to 0.3 grams. At this level, you shouldn't "feel" high. You aren't seeing tracers or thinking the carpet is breathing. It’s sub-perceptual. People do this for depression or creativity, often following protocols like the Fadiman approach (one day on, two days off).
Then you hit the low dose or "museum dose," usually 0.5 to 1.5 grams. Why "museum dose"? Because you can generally go to a museum and look at art without losing your mind, though things will definitely look a bit more... vivid. It's social. It's giggly. You might feel a bit of "body load," which is that heavy, slightly buzzy feeling in your limbs.
The moderate dose is where things get real. This is the 2 to 3.5-gram range. This is the classic "trip." Expect closed-eye visuals, deep philosophical shifts, and probably a few hours where you can't stop laughing at a door handle. This is the dose most clinical studies, like those at Johns Hopkins, tend to hover around when adjusted for body weight (usually 20mg to 30mg of pure psilocybin per 70kg of body weight).
What about the "Heroic" Dose?
Terence McKenna, the famous ethnobotanist, coined the term "Heroic Dose." He defined it as five dried grams, taken in silent darkness.
It’s intense. It’s often scary. At five grams and up, the "you" that you think you are—your ego—starts to dissolve. You might experience what researchers call "ego death." It’s not for beginners. In fact, jumping straight to five grams is a recipe for a challenging experience that could leave you feeling more rattled than healed. Respect the mushroom. It has a way of humbling people who go in too cocky.
Factors That Mess With Your Dosage
You can’t just look at a scale and know exactly what's going to happen. Biological "set and setting" is everything.
- Stomach Content: If you eat a massive burrito and then take your shrooms, they’re going to hit slower and potentially feel weaker. On an empty stomach? They hit like a freight train, usually within 20 to 40 minutes.
- Genetics and Meds: Some people are naturally resistant. Others are hyper-sensitive. Crucially, if you are on SSRIs or SNRIs (antidepressants), they often dull the effects of psilocybin significantly because they compete for the same serotonin receptors. However, never stop medication without a doctor’s guidance just to trip—that can cause serious withdrawal issues.
- The Strain: This is the big one. Psilocybe azurescens is nearly three times as potent as common Psilocybe cubensis. If you have a bag of "Enigma" or "Penis Envy," cut your intended dose in half. Seriously.
Why "Start Low, Go Slow" Isn't Just a Cliché
The biggest mistake? Redosing.
You take a gram. Forty-five minutes pass. You feel nothing. You think, "These are duds," and eat another two grams. Ten minutes later, the first gram hits. Then the next two hit. Now you’re at three grams and climbing, and you’ve realized you’re in way deeper than you wanted to be.
Wait at least two hours before even thinking about taking more. Psilocybin is processed by the liver into psilocin, and that metabolic process takes time.
Understanding the Risks of Higher Doses
It isn't all rainbows and insights. Higher doses increase the risk of "bad trips," which are essentially prolonged panic attacks. You might feel like you’re dying or that you’ve permanently broken your brain. You haven't, but the feeling is very real in the moment.
There’s also a rare but real risk of Hallucinogen Persisting Perception Disorder (HPPD), where visual disturbances last long after the drug has left your system. This is more common with frequent, high-dose use.
How to Actually Measure Your Dose
Don't eyeball it. Just don't.
Buy a jeweler’s scale that measures to 0.01 grams. They cost twenty bucks online. Dried mushrooms vary in density; one large mushroom might weigh the same as ten small "pins," but the alkaloid content can be totally different. Grinding your mushrooms into a powder and mixing them helps "average out" the potency across the batch, ensuring you don't get a "hot spot" of high psilocybin in one bite.
The Lemon Tek Method
Some people swear by "Lemon Tekking." You soak the ground mushrooms in lemon juice for 20 minutes before consuming. The theory is that the acid mimics stomach acid and begins converting psilocybin into psilocin beforehand.
Does it work? Most users report it hits faster, feels stronger, and lasts a shorter amount of time. If you do this, adjust your dose downward. A 2-gram Lemon Tek can feel like a 3-gram dry dose.
Practical Steps for Your First Time
If you’re a beginner, start with 1 gram to 1.5 grams. This is the "safe" zone. You’ll see colors more vibrantly, you’ll feel a sense of wonder, but you’ll stay grounded in reality. You can still use the bathroom by yourself. You can still hold a conversation.
- Secure a Sitter: Have a sober friend you trust nearby. They don't need to stare at you, just be in the next room in case you get anxious.
- Clear Your Calendar: Don't plan on doing anything for 24 hours. The trip lasts 4–6 hours, but the "afterglow" or the mental processing takes much longer.
- Hydrate: Mushrooms can make you sweaty or give you a slight headache. Drink water.
- Check Your Mindset: If you’re going through a crisis or a breakup, the mushrooms will likely force you to face it. Be ready for that.
Finding the right dose is about honesty. Be honest about why you're doing this. If it's for healing, maybe a guided, moderate dose is best. If it's for curiosity, start small. The mushrooms will be there later—you don't have to see the whole universe on Tuesday night.

Take your time. Buy a scale. Respect the molecule. The goal is to come back with something useful, not just to get as high as possible.
Actionable Next Steps
- Invest in a digital milligram scale to ensure you aren't accidentally taking a "heroic" dose when you meant to take a light one.
- Identify your strain before consuming; if it's a "PE" (Penis Envy) variety, reduce your planned dose by 50%.
- Prepare your environment by removing potential stressors, turning your phone on "Do Not Disturb," and having a comfortable place to lie down.
- Wait at least 14 days between sessions to allow your tolerance to reset completely, as psilocybin tolerance builds almost instantly and takes two weeks to return to baseline.
