What Is Psilocybin?

Psilocybin is a natural compound found in psychedelic mushrooms. It’s what gives these mushrooms their mind-altering effects. However, psilocybin doesn’t act directly on the brain. Instead, your body turns it into something else first.

That “something else” is called psilocin. This conversion process is what activates the psychedelic experience.

Research from Johns Hopkins University has shown that psilocybin, once converted to psilocin, may help reduce anxiety, depression, and even addiction. Many researchers now see psilocybin as a promising tool in mental health care.

You can find psilocybin in many of our products at Mycological.co, including gummieschocolates, and infused honey.

What Is Psilocin?

Psilocin is the active compound that causes changes in mood, thinking, and perception. After you eat or drink a psilocybin-containing product, your body turns psilocybin into psilocin. This happens in your stomach and liver.

Once in your system, psilocin attaches to certain serotonin receptors in your brain—especially the 5-HT2A receptor. This interaction is what creates the psychedelic effects.

As explained by the National Institutes of Health, psilocin has a structure similar to serotonin, a brain chemical that affects mood and emotion. Because of this, psilocin can lead to increased openness, reduced fear, and enhanced creativity.


Psilocybin vs Psilocin: A Quick Comparison

Here’s a side-by-side breakdown of the two:

FeaturePsilocybinPsilocin
Where it’s foundIn mushrooms and infused ediblesCreated inside your body
Is it active?Not until convertedYes, directly active in the brain
Role in effectsPrecursor (needs to be processed)Causes actual changes in perception
StabilityLong shelf lifeLess stable, breaks down quickly
How it worksDigested and convertedBinds to serotonin receptors

Understanding this process helps explain why certain products hit faster, last longer, or feel more consistent.

Why Does This Matter?

1. Onset Time Depends on Conversion

Since psilocybin must become psilocin, there’s often a short delay before effects start. Most users feel the first signs within 30 to 60 minutes after eating or drinking a product.

2. Product Freshness Affects Potency

Psilocin is fragile. If mushrooms or edibles aren’t stored properly, psilocin can break down. On the other hand, psilocybin is more stable and holds its potency longer. A 2022 study published in Drug Testing and Analysis confirms this (source).

3. Your Body Influences the Experience

Everyone metabolizes psilocybin at different speeds. That’s why the same dose might feel stronger or weaker from person to person. It also helps explain why mushroom honey may kick in faster for some users than raw mushrooms do.

Final Thoughts

The difference between psilocybin and psilocin is more than just chemistry—it explains why mushroom products work the way they do. Psilocybin gives your body the raw material. Psilocin is what actually creates the experience.

Knowing this helps you choose products with more intention, and ultimately, more clarity.

FAQ

Which one causes the effects?

Psilocin does. Psilocybin is just the starting point.

Why do onset times vary?

It depends on how fast your body converts psilocybin to psilocin.

Is one more potent?

Psilocin is more active, but it’s less stable. Psilocybin stores better over time.

Can I see this in lab tests?

Most lab panels focus on psilocybin levels, since psilocin degrades quickly.

Are both legal?

Both are illegal federally in the U.S. Always check your local laws.
