The R-Files is a series of episodes about rapamycin, a naturally occurring compound originally discovered in soil samples from Easter Island, also known as Rapa Nui (hence the drug's name). Rapamycin belongs to a class of drugs called macrolides and has potent immunosuppressive and anti-proliferative effects. The drug has garnered attention for its potential anti-aging properties and has attracted research interest for its ability to extend lifespan and delay age-related diseases in various model organisms, including yeast and mice.
In the third episode of the R-Files, Matt, who studied rapamycin for over a decade of his career, talks about a recent study evaluating the benefits and side effects of taking rapamycin off-label-that is, for a purpose other than that for which the drug gained FDA approval. Physicians can prescribe any FDA-approved drug off-label as long as they believe it will be beneficial for the patient. Matt discusses noteworthy potential side effects of rapamycin use, the experiences of study participants who took rapamycin, and why off-label rapamycin use is not widespread despite considerable evidence for life- and healthspan benefits in laboratory animals.

Hi, I'm Matt Kaeberlein. I spent the first few decades of my career doing scientific research into the biology of aging, trying to understand the finer details of how humans age in order to facilitate translational interventions that promote healthspan and improve quality of life. Now I want to take some of that knowledge out of the lab and into the hands of people who can really use it.
On this channel I talk about all things aging and healthspan, from supplements and nutrition to the latest discoveries in longevity research. My goal is to lift the veil on the geroscience and longevity world and help you apply what we know to your own personal health trajectory. I care about quality science and will always be honest about what I don't know. I hope you'll find these videos helpful!

Thank you. I just started taking sirolimus in November for recurring post-Covid viral myocarditis, which first happened after the vaccine in 2021 and then several times since after any virus, with Covid being the worst trigger. It's too early to tell, but I'm hoping this will improve what I think is an underlying immune dysfuction and correct the problem. I very much appreciate people like you and other scientists making this sort of information available.

This sounds like exactly what I've been going through although I have not gotten a diagnosis. Seems to have all started after the 2nd pfizer vaccine. After I recover (first time taking 2 years, second time 8 months) it seems to return anytime my immune system is engaged. I'm almost positive its returned this 3rd time after exposure to mold which I really hope is not the case.

@ZoeyKs 3 ай бұрын

@@TwistedPsilo yes, our stories are similar. Diet/lifestyle changes and metformin have helped lessen the severity of my episodes and symptoms, but have not been a cure. If you can see a cardologist and get a diagnosis, there are some medications that can help control it. I'm going to continue with the rapamycin and hope it works. I should mention I had an unusually inflammatory reaction after 10 weeks of taking just 4-6 mg of rapa per wk, which might be due to my immune dysfunction. So I've stopped for now, but plan to restart at 1 mg/wk and monitor CRP closely. Good luck, I hope you can find a solution.

I'm surprised that reduction in fungal infections wasn't included in the survey. My chronic toenail fungus disappeared when I started using sirolumis (10g twice a month) and I wasn't surprised because I was familiar with its discovery as an antifungal medication, but I would be interested in seeing if others have noted this effect...

Very useful study despite the caveats. I am 70 and live a vey unhealthy lifestyle (bad food, lots of alcohol, lack of exercise, overweight, demanding work). The only positive healthy thing I do is bouts of intense cycling for many hours once every few months. At 70, things look good for me from a health point of view,. I have been taking rapamycin for the last 3 or 4 years, but I also take a lot of other things like occasional D+Q treatment and host of other things like NMN, NA, acarbose and what not if not regularly (my discipline is quite poor). I have a suspicion that rapamycin and NAD boosters keep me healthy (since I started taking NA - now switched to NMN - 10 years ago and I noticed a difference in my cycling performance)

some things id love to hear your opinion on: 1. are low protein diets still ideal for lifespan (in lab animals) when controlled for methionine intake? 2. i've heard it said that rapamycin is *just* a CR mimetic. Is this true? Would CR + rapamycin be redundant? 3. which life extension techniques do you think compliment one another (in that they prevent/reverse aging by different mechanisms)? For example, do you think TERT and rapamycin would get much greater lifespan extension in mice than either one alone? 4. do you think senolytics have promise? if so, how do you explain the fisetin ITP trails showing no lifespan extension? 5. if you had 5 million dollars to spend on any longevity study you can think of, which study do you think would get you the most bang for your buck? great episode by the way! love the podcast.

I've tried to milk all there is from Rapamycin (R) scholars like yourself and Peter Attia. Many questions remain though. I've heard comments like "having canker sore is proof R is working". However, I've gone for months without any sore and other times painful ones that go away (on the same weekly dose). How much R per week is too high? (probably is an individual thing?) Are there symptoms indicating mTorC2 inhibition as well as mTorC1, or by then it's gone too far already? Some people test for levels of R in the blood, others use blood markers like red blood cells to indicate negative effects. Are there a list of tests that are a better indicator on R's effects? Is there any idea as to how many people are using R for longevity? Are companies like Pfizer showing interest to off-label use? Given the overwhelming evidence, are insurance companies showing any interest? I can imagine billions saved for them, and are they not a good potential funders of studies? Will you run for president and make R readily available to everyone for free? 😉

@andrewboss2018 4 ай бұрын

I don't think Brian can overstress just how limited these findings are given there was no placebo control as well as immense healthy-user bias. If anything, this is a early proof of concept for Rapamycin's safety in intermittent doses. I say this because I already see self-proclaimed "gurus" sharing this video as if it's groundbreaking information. It is not.

@@mkaeberlein David Pascoe and Bryan Johnson use rapamycin. Michael Lustgarten not. I did not find much info about the others. I think TruDiagnostic and MyDNAge do their best to calculate the biological age. There is a lot of data and computer power to calculate someones life expectancy compared to the average humans. I would certainly do those tests if they were not so expensive ($500 and $300). There are tens of thousands biohackers experimenting and if certain medicines or food supplements do prolong lifespan, it will show up in the Rejuvenation Olympics before it becomes clear in the statistics about centenarians.

CAS 54915-44-7 and CAS 53123-88-9 are both associated with the active ingredient rapamycin, but they are different in the following ways: 1. Molecular formula: CAS 54915-44-7 has the molecular formula C44H69N9O12, while CAS 53123-88-9 has the molecular formula C31H59N7O12. 2. Molecular weight: CAS 54915-44-7 has a molecular weight of 729.07 g/mol, while CAS 53123-88-9 has a molecular weight of 531.24 g/mol. 3. Structural formula: The structural formula for CAS 54915-44-7 is different from that of CAS 53123-88-9. 4. Synonyms: CAS 54915-44-7 is also known as rapamycin, CAS 53123-88-9 is also known as sirolimus. 5. Applications: Both CAS 54915-44-7 and CAS 53123-88-9 are used as immunosuppressants, but CAS 54915-44-7 is also used as an antifungal agent, while CAS 53123-88-9 is used as an anti-cancer agent. 6. Manufacturers: CAS 54915-44-7 is manufactured by Pfizer, while CAS 53123-88-9 is manufactured by Wyeth. In summary, while both CAS 54915-44-7 and CAS 53123-88-9 are associated with the active ingredient rapamycin, they have different molecular formulas, molecular weights, structural formulas, synonyms, applications, and manufacturers.
