For anyone new to Peter Diamandis:
It seems very premature to use it, (for me), but It has some history in longevity research:

and
Doxycycline (40 ) is a broad-spectrum antibiotic of tetracycline type, which can prolong the life span of nematodes and Drosophila melanogaster [182,183,184].

@Krister_Kauppi Peter Diamandis is someone you probably want to add to your longevity experts taking rapamycin.

Yes, I read about using Doxycycline weekly from Blagosklonny. I take it with my GP’s prescription and supervision. I take one 100mg of Doxy per week. Same weekly dose of Peter. For cleaning body of rogue bacteria and parasites… cancer prevention. Heck extends life of flies and worms.
Been on it since April 2022. With rapamycin modulation of the immune system… good to have on hand. Use extra when needed …I have used for several days with clogged eye duct glands when my dose of rapamycin was higher.
Peter also does TRT… twice a week. Interesting.

Doxocycline
Doxocycline, broad-spectrum antibiotics of the tetracycline class, extends life span in C elegans [220] and Drosophila [221, 222]. Doxycycline suppresses tumor growth and metastasis in mice [223, 224]. Importantly, doxycycline is a component of an anti-metastatic combination, which includes doxycyclin, aspirin, lisin and mifepristone [225].

I’ve been on doxy for the last 1.5 years to help with acne. I take 100mg daily with food. In my experience, it’s been very effective. I’m curious to dive into the potential longevity benefits and see which mechanisms it acts on.
Word of caution: if you take doxy on an empty stomach or immediately before lying down, you’ll probably get tremendous nausea. I cannot overstate how bad it feels (!) – you can’t focus on anything else for hours. When I take it with a meal or light snack, I’ve never had a problem.
Exciting to see that Diamandis is on rapa. How to Build a Spaceship is a phenomenal book outlining his quest to build the X-Prize. He’s a visionary who knows how to execute. He’d be a huge asset for the longevity community.

Its interesting… he does say “rapamycin + doxycycline” (Experimental IND Protocol).
That would seem to suggest that someone is trying to patent a combination rapamycin + doxycycline, perhaps the rationale is that if rapamycin provides any immune suppression it would be good to have an antibiotic at the same time? And, there seems to be some potential longevity benefit of doxycycline anyway?
What do others here think?
Other interesting information on things Diamandis uses - if you have any knowledge or thoughts on these, please post below.
A lot of things Peter Diamandis is promoting and using are products that his company(s) are providing, or that he or his partner’s are promoting. On youtube I see that Tony Robbins (partner of Peter Diamandis’ on a number of ventures I believe) is promoting OsteoStrong very heavily in videos. All the Diagnostics that Peter uses seem to be part of the $10K to $20K services his Fountain Life company provides… About | Fountain Life

It’s kind of like the Rapamycin + Metformin or Rapamycin + Acarbose approach. Get the benefits of Rapamycin while treating the secondary effects with another longevity medicine that compliments Rapamycin. I have a feeling that Rapa + Acarbose will still be superior, but I hope I am wrong as I would like something even better!
Maybe it should be recommended to the ITP?

As an antibiotic, doesn’t it damage the gut microbiom and the mitochondria? So will we need another drug to treat secondary effects?

DrM, you present an antibiotic I had never heard of before. It looks very interesting. However, whether taking doxycycline or minocycline on a regular basis what comes to mind is the ability of parasites to gradually adapt to regular dosing with an antibiotic. Do you have any thoughts on this?

Minocycline is a very cheap medicine and useful in a variety of infections. It has shown some off label benefit in Multiple sclerosis and other conditions due to its ability to penetrate blood brain barrier… But it is a valid concern about superinfection and antibiotic resistance if used daily.

I found the monohydrate version of Doxycycline causes much less GI upset.

Doxycycline is an interesting drug. Like a lot antibiotics, its effects don’t exclusively come from the direct action against bacteria. It also has significant effects on a number of inflammatory mediators like tumor necrosis factor and various interleukins.
Those anti-inflammatory actions explain why it is useful at doses below the minimum needed to inhibit bacterial growth. There’s a low dose version (20mg 2xday as Periostat or 40mg delayed release 1xday as Oracea) that was originally used for periodontal disease and was then found to help with rosacea, acne, and dry eye caused by meibomian gland dysfunction. This low dose has been shown not to affect the intestinal microbiome. Even the 50mg dose of doxy has some negative effects in that regard, so 40mg a day is right at the threshold.
There may also be some benefits for atherosclerosis/CVD. There’s not a ton of evidence on that front, but an interesting possibility.

To ward off arthritus I have taken one doxycycline a day for the last 30 years. Arthritus was common in my family and my wife has suffered for years. At 72 I can still work (more slowly) a full day with no arthritus. Been on Rapa 4 years with varied doses and schedule. Happy to read of others’ experiences. Dr. Green’s patient #139

I was surprised and puzzled to see posts regarding the use of doxycycline as part of longevity protocols. One of my areas of interest regarding health and aging is the human gut microbiome. I recently wrote a paper titled The Microbiome Theory of Aging, which was published in the January 2023 issue of the peer-reviewed journal Integrative Medicine. In this article I explain how microbial imbalance (dysbiosis) causes inflammation and intestinal permeability, which ultimately cause tissue and organ damage and the acceleration of biological aging. The gut microbiome regulates many aspects of health and I cannot imagine how taking an taking an antibiotic regularly could promote healthy longevity.
Here is the open access link for my article on The Microbiome Theory of Aging
Warm regards, Ross
