September 2019 Longevity Review


Hello and welcome once again to this month’s longevity update. September has turned out to be one of those month’s where several noteworthy advances have occurred, so that I can’t really decide which is the most important (see round-up below). It’s a great conundrum to have!


On a personally level, my parents have now started their regime, but I got a shock when it emerged from a forum that the Rapamycin they are taking might not be legit. In a subsequent development it appears that there is perhaps Rapamycin in the pills, albeit at a lower dose than advertised - 3.25mg instead of 5mg. Caveat emptor, and just shows the potential pitfalls of being at the cutting edge of self-experimentation before new drugs have been fully approved for an anti-ageing indication. This is also one reason why I have not been actively recommending their use or detailing how I obtained them. However, we all know with certainty what doing nothing at all will eventually result in…


On a more positive note, I’m slowly organizing here in Toronto: created a local Facebook group the “Toronto Longevity Association” and we’re going to be having our first monthly meet-up on October 30th, feel free to join the group even if you are not a local, and if you are, please come along on the 30th. Also, LEAF has asked me to collaborate with them on their monthly news round-up. To start with, I’ll be providing them with sources of information, but we’ll see where this leads…


Follow me on Twitter @ChrisPollyanna1 for the latest updates!
NOTE: I’ve been having trouble linking to the science journal hacking site www.sci-hub.tw , so am only including Full Text links to articles not behind a paywall. I still have been able to download most of them, so if there are any that you are after, I can send them upon request, or you can simply copy the paper’s URL into the site above to get +95% of papers hidden behind paywalls.


September Round-Up:

  • One of the most important developments of the year has been the release of the first in-human senolytic trial results, first in COPD in January and then in Osteoarthritis in June. However, those small trials could not prove that senescent cells had in fact been removed and that it was not some other mechanism behind their results. In this third trial, using Quercetin & Dasatinib in kidney disease, this was shown for the first time, although efficacy results await a future publication. The significance is that the mode of action appears to be the same as it is in mice, which is incredibly encouraging, as the results in mice have been nothing short of spectacular. Keep your eyes peeled for future results because senolytics could well be the first treatment available which could actually reverse certain aspects of ageing.

  • In recent years the epigenetic clock has emerged as a means of assessing someone’s biological, as opposed to chronological, age. This very small trial used a cocktail of two drugs and Human Growth Hormone to increase the size of the thymus, an organ where immune cells go to mature and which atrophies with age. When the researchers measured the subjects’ epigenetic age before and one year after the trial, to their surprise, rather than increasing by a year, it decreased by one and a half - theoretically indicating an age reversal of 2.5 years! I must stress that this was a tiny trial of only 9 people, but this is the first time that epigenetic clock reversal has been documented in humans.

  • OK, this result is in fruit flies, but it is still extremely significant. You might remember that I’ve been banging on about how treatments need to be combined if we’re going to see a sizable effect. So far, such as in this study from last year, the results of combining treatments has been additive, however in this new study, we are seeing synergistic effects ie the sum of the improvement is greater than its parts. Here three molecules: Rapamycin, Lithium & Trametinib each increased lifespan by around 11%, however, when combined this increased to 48%! In addition, Lithium cancelled out some potentially undesirable metabolic effects of Rapamycin.

  • Although not directly related to longevity, this impressive advance nevertheless could prove to be incredibly important in speeding up the drug discovery process, which typically takes quite a long time. If it could be sped up, then new longevity medicines could reach the market sooner. Here researchers have used artificial intelligence to produce a novel drug from scratch in 21 days, which is unheard of. Even more helpful is that the company behind this, Insilico Medicine, is a leading player in the longevity field.

  • Moving on from drug discovery to the drug approval process, the following news is significant because for the first time a drug trial targeting ageing itself is about to be launched, which has not been possible before. It has taken years of effort to first convince the FDA of its merits and then to get the necessary funding together. Although I might not think much of the drug in question (Metformin – see the supplementary section for why), it will make it easier for future, more effective drugs to be approved. And that is to the benefit of us all.

Lifespan.io MitoMouse Crowdfunding Campaign!


Requiring its own subsection is an exciting longevity initiative which YOU can help out with.

Despite the dramatic advances I have detailed in these newsletters, the longevity field remains chronically underfunded, which means that even crowdfunding campaigns can help produce meaningful science. This particular initiative is looking at a novel method to protect our mitochondria (the energy producers in our cells) by transferring their DNA into the nucleus of the cell. Don’t worry about the details – just get out your wallets and donate! The campaign runs until the end of the month and they have already reached their initial goal of $50K, but please help them reach their stretch goals and get more meaningful science done. I’ve donated $70 & will receive a lovely T-shirt & pen in return, but even a measly $10 would make a difference.

Videos to watch & Book to read:

In a slight departure from previous newsletters, I want to introduce a newly published book which I highly recommend everyone to read: "Lifespan: Why We Age and Why We Don't Have To" by Dr. David Sinclair, who has featured in previously recommended videos. In his very readable book, he outlines his new theory on why we age based on over 20 years of work – the Information Theory of Ageing. More significantly, this theory potentially offers a short-cut to true rejuvenation. This is in line with my own belief that epigenetic cellular reprogramming is the next big thing in ageing research. However, this book is not just about theory, as he also delves into current best practices & near term anti-ageing solutions. Most importantly, he also shares my unbridled optimism about where longevity research will take us in the not too distant future.
Google Talk by David Sinclair – in which he outlines his theories & gives a small update on his research post-book publication.
Interview by Dr. Mercola – seemed the best & most in-depth out of the several podcasts interviewing Sinclair that I watched.

September 2019 Supplemental Information


***Disclaimer 1 – As should be self-evident to anyone receiving these emails, I am NOT a doctor or indeed a scientist. All the information pertained within is for information purposes only; use at your own risk. Please consult with a healthcare practitioner if needing medical advice.***
**Disclaimer 2 – In no way should supplements be a replacement for an unhealthy diet or lifestyle. A varied, plant dominant dietary pattern is the cornerstone for health. Try to eat the rainbow – the greater the variety, the greater the benefit. Even though I might take a supplement derived from a plant source, I still eat the plant in question. Also, make sure you move as much as possible – that is what we evolved to do.**
*Also bear in mind that most of the studies mentioned below are in rodents, not humans. Rodents, needless to say, do not always react the same way to drugs as humans do – witness the countless times cancer or another disease has been cured in rodents only to subsequently fail human trials. I have *bolded any human trials.*




Fasting/Dietary Restriction – certainly the cheapest & also one of the most effective anti-ageing interventions currently available. It comes in many flavours, but I fast for at least 12 hours every day.

Non-prescription Supplements (in alphabetical order)
*Due to concerns about engendering homeostasis, I’ve begun varying my intake of supplements so that I’m not taking all of them every day. Haven’t worked out a rota so far.


Astaxanthin – which is behind the pink colour of salmon & shrimp. Considered the most powerful carotinoid, it has anti-oxidative, anti-inflamatory, anti-cancer, neuro-protective and skin-protective qualities. I take 4 or 8 mg intermittently.

Prescription Supplements


MetforminFirst of all, a bit of a mea culpa on my part as I have so far ignored Metformin in these newsletters. If you have ever read any other articles about longevity, then will probably have read about this drug, which is the most commonly prescribed anti-diabetes medication in the world and has been touted as the world’s first anti-ageing drug. It also appears to be most common anti-ageing medicine used by longevity researchers. Why then have I ignored it? Because it failed to produce life-extension in the gold standard of ageing research – the Interventions Testing Program run by the NIA. It might still have beneficial effects, but it also requires a prescription. All year I have been in two minds about its costs/benefits, as witnessed by the unused cartons sitting in my fridge. See the articles below for further details as to why I am reticent.

Any information on which Rapamycin source is compromised?

Oct 26 2019 02:06 AM

Hi Themikemachine,


I got my Rapamycin from antiging.clinic which I found from this forum at age-reversal.net https://forum.age-re...ption-rapamycin


In this same forum page you will find the entry from the person who claims that there was no Rapamycin in the pills as well as the responses from the company, where after some independent testing they say that there is 3.25mg instead of 5mg in the pills.
