More Plates More Dates - $25,000 Follistatin Gene Therapy - Before & After Results Analysis With Peter Attia
The discussion revolves around a gene therapy that aims to inhibit myostatin, a protein that limits muscle growth, by increasing the production of follistatin. This therapy has shown promising results in animals, such as mice and cattle, which exhibit a 'double muscle' phenotype when myostatin is knocked out. However, translating these results to humans has been challenging. The therapy is expensive, costing around $25,000 per shot, and its effectiveness in humans remains questionable. Anecdotal evidence from the bodybuilding community suggests minimal impact, with some claiming significant muscle gain, but these are often unverified and possibly exaggerated claims.
Recent studies, including a phase one trial, showed a modest increase in lean body mass of about two pounds and a slight reduction in body fat, but these results were not groundbreaking. Concerns about the therapy's impact on metabolic markers, such as increased glucose and insulin levels, were also noted. The therapy's mechanism involves a bacterial vector, and while some high-profile individuals have tried it, the lack of rigorous, unbiased studies makes it difficult to draw definitive conclusions. Future trials, particularly those focusing on older adults with sarcopenia, may provide more insights into its potential benefits.
Key Points:
- Gene therapy aims to inhibit myostatin to increase muscle growth.
- Animal studies show significant muscle growth, but human results are modest.
- Therapy is costly and lacks substantial evidence of effectiveness in humans.
- Concerns exist about negative impacts on metabolic markers.
- Future trials may clarify benefits, especially for older adults with muscle loss.
Details:
1. 🔬 Gene Therapy and Myostatin Inhibition: An Overview
- Gene therapy introduces a vector to activate the gene for follistatin, leading to increased production of the follistatin protein, which inhibits the myostatin gene or protein.
- The inhibition of myostatin has significant implications for muscle growth and development, making it a compelling area of research.
- The process involves using viral or non-viral vectors to deliver the follistatin gene into muscle cells, enhancing muscle mass by preventing myostatin from hindering muscle growth.
- Potential benefits include treating muscle-wasting diseases such as muscular dystrophy, with ongoing research aimed at understanding long-term effects and safety.
- Challenges include ensuring targeted delivery, avoiding immune responses, and managing the ethical considerations of gene therapy applications.
- Current studies show promising results in animal models, indicating a potential for significant developments in human applications.
2. 🐭 Myostatin Knockouts: Animal Case Studies
- Myostatin knockout in cattle results in a 'double muscle' phenotype, significantly increasing muscle mass to resemble a 'Mr. Olympia' of the cattle world.
- In mice, myostatin knockout leads to a doubling of muscle fibers compared to wild-type counterparts, exemplifying significant muscle hypertrophy.
- Chickens and dogs with myostatin knockouts also exhibit increased muscle mass, demonstrating a consistent pattern of muscle growth across species.
- These observations highlight the potential implications for animal agriculture and research into muscle-related diseases.
3. 💉 Market and Experimental Gene Therapies
- Gene therapy to inhibit myostatin is being developed, with initial and subsequent shots estimated to cost $25,000 each.
- Studies have shown that myostatin knockouts in animals lead to a double muscle phenotype, and rodent data suggests muscle enhancement with these therapies.
- Research chemical companies offer myostatin inhibitors at high costs, with 1 milligram per vial priced at hundreds of dollars, requiring daily injections costing thousands over a cycle.
- The gray market for myostatin inhibitors has existed for over a decade, but users report limited effectiveness, with most seeing no significant muscle gains.
- Future developments in gene therapy may focus on enhancing effectiveness and reducing costs, while addressing regulatory and ethical concerns.
- Research is ongoing to improve the delivery mechanisms and ensure safety and efficacy of myostatin inhibitors.
4. 📷 Fitness Industry Photo Manipulations
- The fitness industry frequently uses photo manipulation techniques such as strategic angles, lighting, and other visual tricks to enhance perceived muscle gain.
- Before-and-after photos are often misleading, as they can be taken on the same day with significant visual differences due to manipulation techniques such as lighting adjustments, oil application, and optimal conditions like higher temperatures for better vascular appearance.
- Skepticism exists regarding the assays used to measure increases in follistatin, a protein related to muscle growth, highlighting the importance of questioning the validity of such claims.
- Brian Johnson, a biohacker, underwent bacterial vector therapy with no concrete before-and-after metrics on muscle growth, illustrating the skepticism around the effectiveness of advertised muscle enhancement techniques.
