Who is Bryan Johnson?
Bryan Johnson is an American entrepreneur and venture capitalist, best known for his anti-aging project, “Project Blueprint.”
Johnson founded and led several companies, including OS Fund, which invests in early-stage tech and science startups, and Kernel, a company developing devices to track brain activity. He also founded Braintree, a web and mobile payment platform, serving as CEO and chairman before selling it to PayPal in 2013.
The Live-Tweet Magic Mushroom Experience
While he was under the effects of the hero dose, his Blueprint co-founder Kate Tolo took control of his phone and shared updates with his followers. Johnson had mixed the dose with orange juice and consumed it live on X.
First Hour
During the first hour of the experience, Kate shared a photo of Johnson lying in bed with an eye mask, noting that the effects had officially hit.
Johnson said he felt calm and content while listening to drum music, though his sense of time was distorted; he believed far more than an hour had passed.
He became giggly and unusually attentive, repeatedly checking whether Kate had eaten.
He also began hallucinating, saying that Kate’s face and the nearby trees looked alive and appeared to be moving.

Giggly and Excited
Although Johnson said he was having a “fantastic time,” nature eventually called, and he had to take a bathroom break.
When he came back, he reportedly stared at the same cup for about 10 minutes. “What does it mean?” Kate joked as she noted he was still laughing and giggling.
Magic mushrooms can make someone feel giggly, excited, or amazed by their surroundings.
The Peak
About three hours into the trip, Kate tried to collect a vial of Johnson’s saliva while also scanning his brain, checking his blood pressure, and using the sample to assess his adrenal stress levels.
This was the peak of the experience, and Johnson struggled to stay focused.
“He keeps talking about the universe and how we’re all connected,” she said, adding that he wanted to return to his bed and “go back to the playground.”
He also kept calling her a flower, and she joked that getting the device on his head was progress.
After the Trip
About an hour later, Johnson’s trip had ended, and he got his phone back so he could share his own thoughts.
He wrote: “Hey all, I’m just so happy to be alive. Yes, this trip changed me—though probably not in the way you’d expect. People think I’m afraid of death, but I’m not. During my darkest years of depression, I made peace with it. I need a few days to gather my thoughts. I’ll share more soon.”
About 30 minutes later, he tweeted, “It feels like my consciousness is intertwined with yours. Like family. You’re assholes and terrible… mostly. But I love you anyway.”
What’s It Like to Trip on a 5g Mushroom?
Five grams of magic mushrooms is an extremely high dosage. This can trigger intense psychedelic effects lasting several hours.
It’s important to be familiar with mushrooms before trying a 5-gram dose. Johnson had likely used shrooms before, which made it easier for him to take the leap and consume this amount.
For reference, one gram is roughly the size of a single mushroom stem and cap. A heroic dose is about 4–5 mushrooms.
- Intense euphoria and openness
- Colours appeared brighter, sounds more vivid, and time felt slower
- Visual hallucinations with colourful patterns and shapes
- Heightened awareness of surroundings and a sense of connection to everything
- Profound emotional and spiritual effects
- Aftereffects included a refreshed perspective, optimism, and renewed appreciation for nature and simple pleasures.
Note: Not every user will experience all of these effects. The outcome depends on their experience level and preparation.
Should You Try a Heroic Dosage?
Yes, if you have experience with shrooms. Taking a higher dose can be worthwhile. Long-term effects may include increased creativity, enhanced problem-solving, greater empathy, and a deeper understanding of life and relationships.
If you’ve tried shrooms before and want to explore higher doses, here are some strains to experiment with:

Frequently Asked Questions
Can psilocybin mushrooms help slow aging or make you biologically younger?
No. Although Bryan Johnson, who is known for experimenting with anti-aging methods, has tried shrooms, they are not a tool to make you biologically younger. Magic mushrooms are primarily used for medical purposes, such as helping rewire the brain in people with depression or anxiety, or for recreational use to gain insights. They have no proven impact on the aging process.
Why did time feel longer to Johnson during his magic mushroom trip?
It is due to the substance’s effect on the brain’s default mode network (DMN). Psilocybin reduces activity in the DMN, so it alters consciousness and distorts the sense of time. It can also disrupt the brain’s internal clock and heighten focus on the present moment. As a result, time can feel stretched or unreal, even though the actual clock hasn’t moved.
What was Bryan Johnson’s motive for taking psilocybin?
He explained that his recent experiment involved testing 240 biomarkers to study the effects of hallucinogenic drugs on longevity. On X, he wrote, “We’re casting a really wide net to see if we can find anything that shows potential for rejuvenation or longevity effects.”
