The 8 Most-Potent, Strongest Magic Mushrooms on Earth

First, let’s define “strongest” as the most potent magic mushroom species containing the highest amount of Psilocybin (4-phosphoryloxy-N,N-dimethyltryptamine or “4-HO-DMT” for short). This is the main magic compond in psychedelic trips. 

There are two more active compounds in Psilocybin mushrooms, like Psolocin and Baeocystin but they’re not as powerful because they are only a small percentage of philocybin’s amount and not as stable, meaning it won’t last or process enough to the point where it can noticeably impact your trip. 

Secondly, buyers of mushrooms tend too much importance on the strain when forecasting strength. While everyone and their grandpa will give you their opinion about which strains are ‘strongest’, ‘more visual’, or ‘giggly’, quantitive data and studies are lackingt and there are other factors that impact strength. 

Factors Proven to Impact Potency

Most growers and psychonauts will agree these are some of the most important things that impact how strong magic mushrooms are.

Drying method

Most growers will tell you that fan drying in the right temperature is the best way to retain potency. This is similar to pot where a slow drying process creates a more flavorful and aromatic outcome. The worst way is to dry in the sun which I learned the hard way….. I was hosting a ceremony one night and some shrooms I was storing in the closet got a little moist (to the point where I could bend one without breaking it), so I laid them in the sun thinking a little vitamind D won’t hurt. One hour after dosing, everyone asked for more saying they didn’t feel much. I tool 0.5g myself and felt the same. So we started eating more, first one more gram, then more until we had about 10grams each. While I felt got hot flashes, I did not trip. The UV from the sun killed all the potency. 


The Fresher the Better..for potency at least. Mushrooms are more potent when they are fresh, even though consuming them dry is usually preferred to reuduence the chance of nausea. Even if they are dried, newer mushroom are often stronger than older ones, all other factors being equal.  


How long do mushrooms last? Technically, shrooms will be safe to consume as long as they don’t grow mold or bacteria. But this doesn’t mean the Psilocybin won’t deplete. Potency will degrade over time but storing mushrooms in the right condition will prolong their potency. The best way to store mushrooms to retain potency is vacuum sealed with a desiccant pack in the fridge or freezer. The less air the less air-born contaminates; the desiccant pack (the little beanbag you get in shoeboxes to keep shoes dry and fresh) will help suck any remaining mosture, and keeping them cold will prevent bacteria and mold from growing. Basically, aim to reduce the optimal environment for mold and bacteria to grow and destroy the psychoactive compounds. Always check under your mushroom caps for signs of mold before consuming because mold itself is a neurotoxin.


Aborts are kinda like the runts of the litter when it comes to mushroom growing. They stop growing very early after sprouting and their caps turn darker color. To an inexperienced eye, these might seem weak but pound-for-pound potency-wise, they pack the biggest punch. 

How You Can Determine Mushroom Strength

Since most consumers don’t grow their own and instead buy dried mushrooms, their supplier might have inconsistent drying/storing/age factors and the same strain might have different potencies each time. 

Here’s a way you can test a small sample before your ‘trip day’: Let’s pretend you have 12g bag and want to have a medium potency 2g trip but scared they will be too weak or too strong. Start one or two days before with a small amount (0.5-1g) in a setting where you’re able to easily focus and feel. If you don’t feel anything during the test, then consider taking 3g instead of the 2g you originally planned. But if it the mushroom was super strong, consider taking less than 2g during your trip day.

Keep in mind, most people measure strength based on their subjective experience – not based on the percentage of Psilocybin the strain supposedly contains. And there are more factors, both internal and external that can impact your perceived strength. 

How to Increase Strength DURING Your Trip

Have you ever thought you were done tripping only to find yourself back on the peak of the mountain? Yup, it’s common. The average Psilocybin mushroom trip lasts around 5-6 hours with the strongest peak in the middle lasting a couple of hours. 

  • Empty stomach, ground up – for fastest onset, create more surface by blending your shrooms in a coffee grinder and consuming them on an empty stomach. 
  • Decrease distractions – if you’re mind is using all it’s might to focus on distractions (e.g. especially if you’re in a public space, trying to ‘keep it together’), you’re not allowing yourself to fully submit to the experience and feel the effect. This can even be a subconscious defense mechanism so it’s important to jouney in a space free of distractions where your mind and spirit can relax. Wearing an eye mask will block visual distractions. 
  • Music – An essential part of a Psilocybin mushroom journey, music itself can trigger emotions and memories which can be amplified by magic mushroom. 
  • Breathwork – Many different types of breathwork exist that can trigger different emotions and states of consciousness. To ‘sink into a trip’, we recommend long deep breaths and making sure your exhale is longer than your inhale (e.g. 3 sec in, 4 sec out). Be sure to check with a certified breathwork coach and do-your-own research before attempting this.  
  • Take More, but Not Too Early – People have different tolerances and things like food can impact onset time. It’s common for the same person to start feeling it 15 mins after consuming on an empty stomach or 1.5 hours if consuming with a semi-full stomach. Also, based on my experience, sometimes it just takes longer for people feel it and I’m not sure why. Anyways.. Most people should wait 1-1.5 hours after the first before taking more and only take up to two doses, because continuing to take mutliple doses might extend your whole journey beyond the time you wish to finish and get back to ‘normal’ life. 

The 8 Most-Potent Strongest Magic Mushroom Strains 

There are over 150 species of magic mushrooms that contain tryptamine alkaloids such as psilocybin and psilocin. They include the genera Psilocybe (noted as “P” below), Gymnopilus, Panaeolus, Copelandia, Hypholoma, Pluteus, Inocybe, Galerina, and Mycena. These are the most popular species. 

Psilocybe azurescens is widely considered to be the magic mushroom with the highest concentration of psilocybin and could be considered as the strongest mushroom strain on earth. However, this species of shroom tends to be harder to cultivate and thus, not as widely consumed. Psilocybe cubensis strains are much more popular due to their ease of cultivation and yield. Cubensis shroom substrains include B+, Golden Teacher, Ecuador, Mazatapec, Penis Envy, Albino penis envy, Luminous Lucies, and many more.
