Bryan Johnson’s gene therapy: What you need to know

Read about Bryan Johnson’s gene therapy to learn how the treatment works, what Bryan’s results were, and whether genetics can help you stay healthy and young.

October 28, 2024

The application of gene therapy, a procedure that can modify a person’s genes to help treat diseases, expands beyond medical treatments and is used to boost longevity and well-being. This method has made the news recently thanks to Bryan Johnson, a centimillionaire known for his zealous attempts to slow down aging. He underwent gene therapy at the beginning of 2024 and documented his experience.

If you’re curious about Bryan Johnson’s gene therapy, we’ll present the procedure, its effectiveness, and potential side effects, breaking down the available information and giving you a realistic assessment of the treatment and its perceived benefits. 


The basics of Bryan Johnson’s follistatin gene therapy

Bryan Johnson opted for follistatin gene therapy. As the procedure isn’t available in the U.S., Johnson had to travel to Prospera, a private, self-governing experimental zone and startup hub on Honduras’ Roatan island, to access it. 

The therapy currently costs $25,000 and is available only in the GARM Clinic on Roatan and the Eterna Health Clinic in Dubai.

Minicircle, the company that produced and delivered Bryan’s therapy, is one of the pioneers in human genetic enhancement. Although it has only completed a Phase I clinical trial on follistatin gene therapy, Minicircle claims that the treatment has shown great promise, ranking among top lifespan studies.

How follistatin gene therapy works

Minicircle’s follistatin gene therapy involves the injection of follistatin, a protein your body naturally produces, into your stomach fat. Follistatin inhibits the activity of myostatin, another protein that limits muscle development to prevent overgrowth. 

According to Minicircle, follistatin gene therapy might be able to:

  • Increase muscle mass and strength

  • Delay the onset of aging

  • Reduce the epigenetic clock age

The company also claims that the treatment may be able to elongate telomeres (chromosome ends), which in turn promotes longevity and mitigates the risk of age-associated diseases like:

  • Cancer

  • Heart disease

  • Neurodegenerative conditions

To deliver follistatin, Minicircle uses plasmids, small circular DNA molecules independent of your chromosomal DNA and don’t edit or integrate into it. Plasmids can be regulated with activator pills, which ensures treatment reversibility and adds to its safety. Its effects can be eliminated instantly with an antibiotic in case of adverse reactions.

Is follistatin gene therapy backed by science?

There’s not enough scientific evidence to confirm the safety and efficacy of follistatin gene therapy for longevity purposes. Most of the research has been conducted on animals, with one 2022 study demonstrating that the therapy has extended the median lifespan of mice by 32.5% and increased their muscle mass two-fold without increasing the risk of cancer.

We can’t generalize these findings to people, though. In research on humans, follistatin gene therapy has shown potential to be a safe and effective form of treatment for muscle diseases like Becker muscular dystrophy, but its anti-aging properties haven’t been validated.

The U.S. Food and Drug Administration (FDA) has yet to approve follistatin gene therapy, which is why Bryan Johnson had to get it in Prospera. We need more research on human subjects to determine its life-extending properties and rule out long-term side effects.

 

Bryan Johnson’s results after gene therapy

As part of his Project Blueprint, Bryan monitors his biomarkers regularly to assess his progress and the effectiveness of individual treatments and products. He reported the following results after completing gene therapy: 


|                    |                                                                    |                |
| ------------------ | ------------------------------------------------------------------ | -------------- |
| Follistatin levels | Increased by 160%                                                  | 3 weeks later  |
| Muscle mass        | Increased by 7%                                                    | 6 months later |
| Speed of aging     | Reduced to 0.64 (personal best and lower than 99% of 20-year-olds) | Unknown


Keep in mind that Bryan subjects himself to a wide range of treatments and maintains a generally healthy lifestyle through:

  1. Regular exercise

  2. A meticulously crafted vegan diet

  3. Consistent, high-quality sleep

Because of Bryan’s comprehensive approach, these improvements can’t be attributed solely to gene therapy.

What is the future of genetics and gene therapy?

Gene therapy is rapidly evolving and finding its application in various areas of medicine, including the treatment of rare diseases. According to Nature, over 2,000 gene therapies are currently being developed. Also, researchers at the University of Massachusetts predict that the FDA will approve over 60 gene therapies by 2030. 

One of the latest developments in gene therapy is CRISPR, a technology that allows scientists to edit patients’ genomes, fix defects, and help treat different conditions.

Casgevy, a new CRISPR-based therapy for sickle cell anemia, one of the most common inheritable conditions in the world, can be revolutionary for patients. The treatment has emerged as a much more convenient and less invasive option than bone marrow transplants, which were the only available cure until recently.

While these therapies are impressive and promising, most people still can’t access them because they are extremely expensive. Some treatments even had to be withdrawn because of their low commercial potential and exorbitant prices, often reaching millions. The truth is that people in developing countries, who typically need gene therapies the most, are least likely to benefit from them. 

The democratization of genetic knowledge

Gene therapy may still be out of reach for most people, but genetic testing is the most accessible it’s ever been. While it required a doctor’s visit and thousands of dollars before, companies such as Ancestry and 23andMe now allow customers to buy tests for less than $100 and take them without leaving their homes.

This shift has enabled a large number of people to learn about their genetic composition and even get basic insights into potential health risks. Still, while these direct-to-consumer tests are suitable for ancestry analysis and relative matching, they can’t offer complete and dependable health assessments — primarily because they use limited genotyping technology, which decodes only 0.1% of your DNA.

The latest developments in genetic testing

On the upside, analysis technology has evolved significantly over the last few years. First, we've seen the rise of next-generation sequencing and then whole-genome sequencing, technology that can read almost all 6 billion data points of your DNA

Nowadays, physician-ordered tests can analyze your entire genetic code and provide detailed reports on your genetic health. They're as easy to obtain and take as commercial-grade tests. While the first whole-genome sequencing endeavor cost $3 billion and took 13 years, at-home tests like Nucleus Premium are now available at affordable prices.

Nucleus can give you insights into your genetic risks, allowing you to take better ownership of your health and secure a brighter future for you and your family.
