More Plates More Dates - Bryan Johnson's $25K Follistatin Gene Therapy - Dissecting The Results
The conversation delves into various anti-aging therapies, with a significant focus on gene therapy involving follistatin. This therapy showed a 30% lifespan extension in mice and increased follistatin levels by 160% in humans. However, the therapy's effects on humans are still under scrutiny, with mixed results in clinical trials. While some markers like lean body mass showed improvement, others like insulin resistance and lipid profiles raised concerns. The therapy is experimental and costly, with a $25,000 price tag per shot, and its long-term benefits remain uncertain. The discussion also highlights the challenges in measuring the effectiveness of such therapies, emphasizing the need for rigorous statistical models to isolate effects amidst various confounding factors. The team involved in these experiments employs comprehensive research and statistical methods to ensure the reliability of their findings, although the results are still emerging and not definitive.
Key Points:
- Gene therapy using follistatin showed a 30% lifespan extension in mice and increased follistatin levels by 160% in humans.
- Clinical trials revealed mixed results, with improvements in lean body mass but concerns over insulin resistance and lipid profiles.
- The therapy is experimental and expensive, costing $25,000 per shot, with uncertain long-term benefits.
- Measuring the effectiveness of such therapies is challenging, requiring rigorous statistical models to isolate effects.
- The research team uses comprehensive methods to ensure reliability, but results are still emerging and not definitive.

1. 💊 Revisiting Metformin in Anti-Aging
- Metformin is being explored as an anti-aging drug due to its established safety profile and widespread use in diabetes treatment, contrasting with more exotic options.
- Research indicates Metformin's potential to extend lifespan and improve healthspan, with animal studies showing increased lifespan and improved metabolic health, although human data remains limited.
- Specific studies in animal models have demonstrated up to a 38% increase in lifespan, highlighting Metformin's potential impact on longevity.
- The cost-effectiveness of Metformin makes it a viable option for large-scale public health strategies targeting aging.
- Further investigations are needed to confirm the anti-aging effects of Metformin in humans and to understand the mechanisms involved, such as its influence on cellular metabolism and inflammation reduction.
2. 🔬 Exploring Alpha Estradiol and Other Interventions
- Alpha Estradiol, once considered a promising treatment, is now questioned for its effectiveness.
- Despite its benign profile, Alpha Estradiol has shown limited noticeable benefits in recent studies.
- The initial reputation of Alpha Estradiol was based on its potential for minimal side effects, yet its actual impact appears negligible.
- Recent evidence and expert opinions have challenged the previously assumed benefits of Alpha Estradiol, highlighting a need for reevaluation.
3. 🧬 The Impact of Gene Therapy on Longevity
- Gene therapy using mini circles and a plasmid for full-stat gene therapy ranked seventh in extending lifespan, achieving over 30% increase in mice lifespan.
- Following the therapy on September 10th, full stat levels increased by 160% within two weeks, indicating significant effectiveness.
- The therapy increases fostatin production by residing within the nucleus, rather than editing genes.
- Development challenges included issues with AAVs like AAV9, as the therapy cannot be deactivated once applied.

5. 🔍 Understanding Myostatin Inhibition and Body Composition
- Researchers are examining over 30 organs to understand the effects of myostatin inhibition, which has been primarily associated with muscle.
- The study is also assessing epigenetic age, speed of aging, and inflammation as markers.
- There is a significant effect size observed in increased lifespan, suggesting other bodily effects that are not yet robustly measured.
- A company is conducting extensive gene therapy mini-circle measurements, more than any other entity, to capture these effects.
- The research includes discussions with a prominent spokesperson, indicating active engagement in the scientific community.
- There is an interest in understanding the cost-effectiveness or ROI of the therapy per shot, which is important for practical implementation.
6. 📊 Clinical Trials: Outcomes and Concerns
- Phase one trial on gene therapy showed a decrease in biological age markers, indicating potential anti-aging benefits.
- Participants experienced an increase in lean body mass by 1.8 pounds and a decrease in body fat by 0.8 pounds, suggesting improved body composition.
- However, the therapy induced negative health markers: insulin, glucose, and hemoglobin A1c levels increased, posing a risk of pre-diabetes.
- Changes in lipid profiles included increases in both LDL and HDL cholesterol, requiring careful monitoring.
- A significant concern is the therapy's cost of $25,000 per shot, raising questions about its cost-effectiveness relative to cheaper alternatives like creatine monohydrate, which might offer similar benefits.

8. 🤔 Challenges in Interpreting Biological Age Reductions
- Interpreting the effectiveness of interventions like gene therapy is challenging due to the lack of clear targets, often perceived as trial and error ('throwing darts against the wall').
- A rigorous approach is undertaken in clinical studies, exemplified by a recent self-experimentation study involving thousands of participants, which included detailed research on grape seed extract's effectiveness.
- The team's proprietary research and protocols are robust, but the lack of transparency about their internal methodologies leads to skepticism.
- Despite external skepticism, internal reviews reveal a thorough and sophisticated approach, often surprising critics who engage with the team's methodologies.
- Over 200 assessments have been conducted with a robust protocol, although the results are still emerging and not all questions have been answered.
- Claims of significant reductions in epigenetic age (e.g., minus 27.9 years) are met with skepticism, as they do not necessarily correlate with increased lifespan.
