Psilocybin Chocolate Canada: Magic Mushroom Chocolate Bars by STEM

Psilocybin chocolate from STEM is made in Vancouver, BC, with Belgian Callebaut chocolate and measured mushroom doses in every piece. We started STEM to break the stigma around magic mushrooms and to make microdosing simple, clear and easy to learn. We believe that by changing our minds, we can change our lives.

Every bar is scored into pieces with a set amount of mushroom in each, so you always know what you are taking. Our standard bars hold 3 grams of mushrooms split into 15 pieces, which works out to 200 mg per piece. Cut a piece in half for 100 mg or into quarters for 50 mg. That is how most of our customers build a steady microdose routine with mushroom chocolate bars.

We ship discreetly across Canada, with free shipping on orders over $200. Live in Metro Vancouver? We offer free local delivery on orders over $300. From Vancouver to Toronto to Halifax, our shroom chocolate bars arrive sealed, labelled and ready for you.

Why Choose STEM Mushroom Chocolate Bars?

Here is why people across Canada pick STEM. We care about two things more than anything else: what goes into the bar, and how clearly we tell you what is in it.

Mental health touches almost every family in this country. The Canadian Mental Health Association reports that 1 in 5 people in Canada will personally experience a mental health problem or illness in a given year, and that by age 40, about half of the population will have or have had a mental illness (CMHA). Many of the people who reach out to us are looking for a gentler, more natural routine, and they want honest information before they try anything.

That is the gap we set out to fill. Our psilocybin chocolate bars pair real chocolate with clear dosing, plain-language guides and a team that answers questions. We think the chocolate should taste great, and the label should tell you exactly what you are getting.

Belgian Callebaut chocolate. Dark, milk and vegan options made with a chocolate chefs trust.
Measured pieces. Each bar lists the strain, the total mushroom weight and the amount per piece.
Microdose and macrodose lines. Separate products for small daily amounts and for full experiences.
Vegan choices. Our Dark Matter bar and our drip bars use 100% vegan chocolate.
Made in Vancouver. Small batches, handmade by our team in BC.

How Psilocybin Chocolate Works

Let’s break it down. Psilocybin is the natural compound found in magic mushrooms. When you eat it, your body converts psilocybin into psilocin, and psilocin acts on serotonin receptors in the brain, mostly the 5-HT2A receptor. A clinical study of oral psilocybin found that psilocin levels peak about 2 hours after a dose, and that the felt effects lasted around 5.5 to 6.4 hours at the doses tested (Holze et al., 2023).

Health Canada says the effects of magic mushrooms usually begin within 15 to 45 minutes and last about four to six hours (Health Canada). Chocolate is a food, so your stomach, your body weight and what you ate that day all shape how fast a piece of mushroom chocolate kicks in. A light stomach usually means a faster start.

Why chocolate instead of dried mushrooms? Raw mushrooms are hard to dose. Potency changes from one mushroom to the next and even between parts of the same mushroom, and many people find the taste bitter and earthy. Health Canada notes that potency varies between mushrooms and batches. Our bars divide a set weight of mushrooms across every piece: 3 grams over 15 pieces in our standard bars, so each piece carries 200 mg. You get a predictable piece and a far better taste.

Microdosing means taking a small amount, often 0.1 to 0.3 grams of dried mushroom, that most people describe as sub-perceptual. You should not see visuals or feel high. Many of our customers tell us they notice a lighter mood, steadier focus or more creative energy on microdose days.

We also want to be straight with you about the research. The strongest clinical results so far come from full therapeutic doses given with professional support, not from microdoses. In a Johns Hopkins trial of 24 adults with major depression, 71% had a clinically meaningful response four weeks after psilocybin-assisted therapy, and 54% were in remission (Davis et al., JAMA Psychiatry, 2021). An Imperial College London trial of 59 people found psilocybin performed about as well as a common antidepressant on its main measure, and the authors called for larger and longer studies (Carhart-Harris et al., NEJM, 2021).

Microdosing research is earlier. The largest placebo-controlled microdosing study, run by Imperial College London with 191 people, found that both the microdose group and the placebo group felt better, with no clear difference between them (Szigeti et al., eLife, 2021). In our view, that makes a careful, journaled routine even more useful. Track how you feel, keep doses small and steady, and decide what works for you.

Microdose vs Macrodose Magic Mushroom Chocolate

Here is how our range lines up by dose:

Microdose bars and bon bons. Our 3 gram bars split into 15 pieces of 200 mg, which you can cut down to 100 mg or 50 mg. Our microdose bon bons come as a single 200 mg bon bon or a 5 pack of 100 mg bon bons.
Macrodose bars. Our 6 gram bars are for people who want a full psilocybin experience and plan for it with a safe setting and a trusted friend.
Penis Envy bars. Bars made with the Penis Envy strain, a cubensis variety known for its strength, in dark, milk and cookies and cream.
Capsules and teas. 250 mg microdose capsules, 100 mg adaptogen capsules, and three psilocybin teas: Sencha Fujiama green tea, peppermint, and red rooibos chai.

How to Start Low

Next steps for a first try:

Start with a quarter piece (50 mg) or a half piece (100 mg) of a microdose bar.
Wait at least two hours before you decide how it feels. Do not take more in that window.
Take it on a calm day with no driving and nothing important planned.
Skip alcohol, cannabis and other drugs. Health Canada warns that mixing raises the risk of serious side effects.
Write down the dose, the time and how you felt. Adjust slowly over several sessions.

Our how-to-use guide walks through each step in more detail.

If you take medication, have a heart condition or a personal or family history of psychiatric illness, talk to a health care professional first. Health Canada notes that psilocybin raises heart rate and blood pressure, and that psychiatric conditions may increase the risk of side effects.

What is psilocybin chocolate, and how does it work?

Psilocybin chocolate is chocolate made with psilocybin mushrooms, with the dose divided across the pieces of the bar. After you eat it, your body converts psilocybin into psilocin, which acts on serotonin receptors in the brain. Depending on the amount, the effects range from a subtle lift in mood and focus at a microdose to strong changes in perception at a full dose. STEM bars list the total mushroom weight and the amount per piece on every product page, so you can choose a dose on purpose rather than guess.

How much psilocybin chocolate should a beginner take?

Start small. A microdose is commonly 0.1 to 0.3 grams of dried mushroom, which is a half piece to one and a half pieces of our standard bar. A quarter piece (50 mg) is a gentle place to begin. Wait at least two hours before taking any more, and only raise the amount over later sessions. Avoid alcohol, cannabis, SSRIs and lithium, and speak with a health care professional if you take any medication.

What is the difference between microdosing and macrodosing?

A microdose is a small amount, often 0.1 to 0.3 grams, that most people describe as sub-perceptual: no visuals, no trip, just a light shift in mood or focus for some. A macrodose is a larger amount, often 1 to 3.5 grams or more, that produces a full psychedelic experience with changes in perception, emotion and sense of time. Our microdose and macrodose lines are separate products, so the bar you pick matches the experience you want.

Can psilocybin chocolate help with anxiety or depression?

Clinical trials at Johns Hopkins and Imperial College London show promise for psilocybin in depression when it is given at therapeutic doses with professional support. Research on microdosing is earlier, and a large placebo-controlled study found similar improvements in the placebo group. Psilocybin is not an approved treatment in Canada, and STEM chocolates are not intended to diagnose, treat or cure any condition. Please talk to a health care professional before adding psilocybin to a mental health plan.

How does STEM keep every dose consistent?

Every STEM bar is made to a set mushroom weight. Our standard bars hold 3 grams split across 15 pieces, so each piece carries 200 mg, and our 6 gram bars and bon bons list their amounts the same way. Each product page names the strain, the total weight and the amount per piece. Inconsistent dosing is one of the most common complaints about psilocybin products, and it’s the problem we set out to solve. Testing matters in this category. Researchers at Oregon State University bought 12 “magic mushroom” edibles from shops in Portland, Oregon, and none of them contained psilocybin, while seven held ingredients that were not on the label. Knowing who made your chocolate, and what is in it, is the whole point.

Is psilocybin chocolate legal in Canada?

Psilocybin is a controlled substance in Canada. Health Canada states that selling, possessing or producing psilocybin is illegal unless Health Canada authorizes it. Legal access runs through approved clinical trials, the Special Access Program (a regulated health care practitioner must apply), or an individual exemption under subsection 56(1) of the Controlled Drugs and Substances Act. No psilocybin therapeutic product is approved in Canada yet. Read our Canadian legal guide for more detail, and check the current rules in your province before you buy.

How long does psilocybin chocolate take to kick in?

Health Canada says the effects of magic mushrooms usually begin within 15 to 45 minutes and last about four to six hours. Chocolate can take a little longer than raw mushrooms because it is a food, and an empty or light stomach often speeds things up. Clinical data shows psilocin levels peak about 2 hours after an oral dose. That is why we ask you to wait at least two hours before you take more. Our guide on how long shroom chocolates take to kick in covers this step by step.

How is psilocybin chocolate different from raw magic mushrooms?

Raw mushrooms vary in strength from one mushroom to the next and even between parts of the same mushroom. They also taste bitter, and some people feel queasy after eating them. A STEM bar divides a set weight of mushrooms across its pieces, so each piece holds a set share of the total, and the chocolate makes it far easier to eat. You get a more predictable dose and a treat you actually enjoy.

What flavours of mushroom chocolate does STEM make?

Our range rotates, and current bars include Dark Matter (vegan dark chocolate), Milky Way (milk chocolate), Cookies and Cream Dreams, Caramel Gold Rush, Matcha Cha Cha, Vegan Mylk Amatika, the Passionfruit Triptych and Yuzu and Me. Our vegan drip bars include Peppermint Twist and Cardamon Spice. Prefer a drink? Try our psilocybin teas in Sencha Fujiama green, peppermint and red rooibos chai.

What does a psilocybin chocolate experience feel like?

At a microdose, most people feel nothing obvious. Some notice a calmer mood, sharper focus or more creative energy. Think of it as a small daily habit rather than a trip. At a full dose, people often report brighter colours, visual patterns, strong emotions, a changed sense of time and deep reflection. Health Canada lists possible side effects too, including anxiety, confusion, nausea and a faster heart rate. Plan a full experience for a safe, calm place with someone you trust.
