What Is Rapamycin?

Rapamycin is an FDA-approved immunosuppressant that researchers first isolated from Streptomyces hygroscopicus on Easter Island in 1972. Physicians began using it for organ transplant recipients because it inhibits the mTOR pathway, which regulates cell growth and metabolism. Scientists studying longevity and age-related diseases now investigate rapamycin for its potential to improve lifespan by slowing cellular aging. Studies with mice—including those published in journals such as Nature (Harrison et al., 2009)—showed rapamycin extended lifespan by as much as 14%. Physicians and researchers, including Peter Attia, focus on its ability to interfere with cellular senescence and promote autophagy when considering it as a pharmacological therapy for aging.

Peter Attia’s Approach to Rapamycin

Peter Attia bases his rapamycin dosage protocol on a data-driven assessment of benefits and risks, often referencing existing animal and limited human research. You’ll notice his approach differs from typical medical dosing, favoring strategies tailored to support long-term health goals rather than immunosuppression.

Typical Rapamycin Dosage According to Peter Attia

Attia typically uses a weekly dosing schedule. You’ll find he references 5-10 mg taken orally once per week as a common regimen (source: The Drive, episode #193, 2023). He avoids daily dosing since weekly administration reduces the risk of side effects linked to immune suppression, such as mouth ulcers or lower white blood cell counts. Dosage can depend on your age, sex, and sensitivity, so Attia often starts patients at a lower dose and adjusts based on response. He doesn’t recommend higher or more frequent dosages outside specialist care or clinical studies.

Frequency and Duration of Use

Attia usually prescribes rapamycin in weekly cycles, emphasizing intermittent dosing to allow mTOR activity to recover between doses. Most protocols in his practice involve 5-10 mg once each week for several months, followed by periodic reassessment. He sometimes cycles off rapamycin entirely to monitor long-term effects and minimize cumulative risk. Continuous use without breaks isn’t standard in Attia’s practice. Monitoring through blood work and physician-guided adjustments is central to his approach, ensuring safety and effectiveness for those using rapamycin in a longevity context.

Potential Benefits for Longevity

Intermittent rapamycin dosage targeting the mTOR pathway can support longevity by slowing cellular aging and promoting autophagy. Animal studies, such as those in mice, achieved lifespan increases of up to 14% with periodic administration (Harrison et al., 2009).

Human research remains limited, but Attia highlights these mechanisms for their ability to reduce cellular senescence and optimize metabolic regulation—factors linked to delayed onset of age-associated diseases.

Clinical examples include:

• Enhanced mitochondrial function, supporting higher energy output.
• Lowered inflammation markers, which are implicated in cardiovascular and metabolic disorders.
• Improved tissue maintenance by increased autophagic activity, reducing cellular debris.

Personalized protocols monitored by bloodwork seek to maximize these advantages while minimizing immune suppression.

Possible Side Effects and Risks

Rapamycin as an mTOR inhibitor also presents several risks, which Attia addresses in his dosing guidelines.

Documented side effects include:

• Mouth ulcers and gastrointestinal discomfort in >5% of patients receiving higher or daily doses.
• Elevated cholesterol and triglyceride levels, requiring regular lipid monitoring.
• Impaired wound healing and increased infection risk, especially with immunosuppressive levels above the standard longevity range.
• Potential for insulin resistance at higher cumulative exposure rates.

Attia’s weekly protocol and periodic drug holidays aim to reduce frequency and severity of these reactions. Regular laboratory assessment forms the foundation of risk mitigation, letting you detect problems early and adapt dosing accordingly. Tight physician supervision remains crucial due to unpredictable individual responses.

Key Considerations When Following Peter Attia’s Rapamycin Protocol

• Individualization and Medical Oversight

Attia’s rapamycin protocol focuses on personalized dosing, with physician supervision being central for optimal safety. You increase the reliability of results and reduce risk when you work with a qualified clinician familiar with rapamycin’s longevity applications.

• Dosing Frequency and Schedule

Weekly rapamycin dosing, with intervals of 5-10 mg, underpins Attia’s approach and helps avoid chronic immunosuppression. You benefit from this strategy during long-term administration, as it allows immune system recovery between doses.

• Baseline and Ongoing Laboratory Monitoring

Blood tests monitor immune function, lipid changes, kidney markers, and glucose metabolism. You help identify side effects and effectiveness when you track these values before and during rapamycin cycles.

• Management of Side Effects

Mouth ulcers, lipid increases, and delayed wound healing rank as frequent side effects. You minimize adverse events when you report symptoms promptly and follow accessory protocols—examples include lipid-lowering therapy or dose adjustment.

• Lifestyle and Medication Interactions

Drug interactions and specific lifestyle factors—like concurrent immunomodulatory medications or recent surgeries—can impact rapamycin’s safety. You gain a more accurate risk profile when you disclose all medications and key health events to your provider.

• Cyclic Protocol Adjustments and Drug Holidays

Intermittent cycling of rapamycin and scheduled drug holidays feature in Attia’s risk-mitigation recommendations. You further support metabolic and immune system health when you integrate these off-periods, based on your response and physician input.

• Long-Term Health Strategies

Combining rapamycin with pillar strategies—nutrition, physical activity, sleep, and stress management—enhances outcomes for longevity. You optimize the benefits of rapamycin when you maintain this multifaceted approach.

Conclusion

Exploring Peter Attia's rapamycin dosage protocol offers you a unique window into cutting-edge longevity science. With his data-driven mindset and commitment to safety you get a practical framework for considering rapamycin in your own health journey.

If you're interested in this approach always seek guidance from a knowledgeable healthcare provider. Combining Attia's insights with a strong foundation of healthy habits can help you make informed decisions and optimize your long-term wellness strategy.
