New users starting up on Rapamycin!

After spending most of my “filler time” reading through nearly all the forum posts on this site, I’ve ordered 150mg of Sirolimus (Zydus) via IndiaPost.

I’m 37yo male, an engineer, with wife & 3 kids. But Rapamycin isn’t for me, it’s for my parents (although I probably will try it to see if it helps with a right knee which is starting to ‘zing’ during 5+ mile runs, and some lower back pain–not holding my breath though).

I got Peter Attia’s new book Outlive for my parents and they read it very fast (not being big readers). My mom is 70 and my dad is 73. Neither of my parents drink much alcohol, and they eat pretty darn healthy–abundance of vegetables, supplements, etc etc. Generally health-conscious people, but nothing overboard. They both work out extensively–mom: Barre3 daily; dad: long 2-3 hour sessions at the gym 3-4 times a week. However, previous to reading Outlive, he wasn’t super detailed about his heart rate zones, and likely far too much aerobic vs resistance training. Now he’s mixing both aerobic & resistance training and better optimizing his time at the gym because of Outlive book.

Then came the Rapamycin chapter. Both were immediately excited to try it. My mom (70yo) talked with her doctor (45yo female) and the Dr., surprisingly, expressed her excitement, and how she listens to Peter Attia, Huberman, and Mathew Walker all the time on her drive to work. My mom didn’t ask for a Rapamune prescription, but likely could’ve gotten it prescribed had she not said, “My son is getting Sirolimus for me.” I sent a list of things for her Dr. to watch out for (thanks to this forum) and it sounds like her Dr. is on it. So I feel comfortable now with a real Dr. involved, and one that has been following my mom’s health journey for 10+ years… so it’s not just me tinkering w/my parents health (no matter how many videos of Matt’s, Peter, Dr. Alan Green, etc etc I’ve watched).

My dad’s main thing, and really, biggest love, is Golf, then with Pickleball in a close 2nd. Without those 2 things, my dad’s life & happiness would probably drop in half, or more. At 73, he’s starting to really feel it, and he is afraid he may have to give up golf this summer (golf season really picks up June - September here, in the Pacific Northwest). So, this is a perfect timed test/experiment, with a goal set. Get my dad on a dosing schedule, slowly ramping up (I’m going to try 14-day intervals due to the high half-life of Sirolimus), and see if he turns around fast enough for his golf game to continue for another 10 years+ instead of stopping at only 73.

After reading through all the great self-experimenters on this forum, & keeping side effects in check, and mTORC2 in check in reference to the long half-life, I’m thinking of this dosing schedule:

73yo Dad, 175lbs

  • Week 1 - 1mg
  • Week 2 - 2mg
  • Week 3 - 3mg
  • Week 4 - 4mg
  • Week 5 - 0mg
  • Week 6 - 5mg
  • Week 7 - 0mg
  • Week 8 - 5mg
  • Week 9 - 0mg
  • Week 10 - 5mg
  • Week 11 - 0mg
  • Week 12 - 5mg
  • Week 13 - 0mg
  • Week 14 - 5mg

It will then be the beginning of August, and hope his golf game is in full swing!

For my mom, essentially the same thing, but I’m going to stop her at 4mg peak dose every 2 weeks since she is roughly 25% less mass than my dad.

Additionally, we have a Golden Doodle (Oliver) that just turned 8, and for the first time, damnit, is starting to go much slower as he ‘pulls’ himself up on our couch. I am going to get him up to 6mg/week (per Ageing Dog Project dosing), since the half-life in dogs is about 40 hrs (compared to around 60hrs for humans). Maybe just do it for 8 weeks or so and see how he is doing.

My brother’s dog is 9yrs old, girl, and has cancer. I was thinking of getting her on it, but I fear I don’t want to get too involved with that, as the vet said she only has 6 more months to live, the tumor is large, and the studies are a bit mixed on the efficacy of Rapamycin on cancer after it has grown to this size. But I’m all ears to any and all feedback.

Anyway - there ya go. Thought I’d share what I’m up to and not just consume all this great knowledge without giving something back to the community. I’ll update this with any big milestones, or side effects (good or bad!). Shoot any holes in anything you see here.

Thank you so very much,




Thanks for the great introductory post - its really helpful when people write up their thought process on what they are doing.

Your approach with your parents sounds entirely reasonable, though perhaps a little conservative in terms of the week on, week off starting at week 5 to 10 (being conservative to start with is of course fine). If things go well, you may want to migrate towards weekly dosing which is what most people do. If you have not done so already, I recommend reading this entire thread: What is the Rapamycin Dose / Dosage for Anti-Aging or Longevity?

If you can, I encourage tracking as much as you can in terms of blood testing and functional outcomes.

You can see from these posts some examples of how people are doing this:

Here: My Lab and Fitness Results After 3 months of Rapamycin Use

Here: Blood Tests and Biomarkers pre-Rapamycin

Here: Impressive Biological Age Reductions with Rapamycin (anecdotal)

And if you can share results, positive or negative, its greatly appreciated as we are all still learning here and the more data we can all share, the better!


Is that dosing schedule with or without grapefruit juice? With it, it looks pretty aggressive. Without it looks pretty conservative. To me, it looks like a schedule for a grapefruit juice drinker.


No grapefruit juice.

Sorry for the long post, this is me, more-or-less, thinking out loud.

Yeah, my proposed dosing schedule is definitely on the conservative side of things. However, we don’t know enough IMHO of this drug, long-term, like 10-30 years. Yes, it’s unlikely my parents are going to make it another 30 years, but still–until we see large-scale, double-blind placebo studies, there’s still a risk, even if I think (or maybe a better word is “feel”) the risk is around 10% that there is a severe side effect lurking under all this seemingly good news, there’s still a too high of a risk for my (maybe overly conservative) conservative mind… Sure, Rapamune has been FDA approved since 1999, and typically given at 6mg on the first day, directly after organ transplant, then 2mg/day after that, then the dose is adjusted after 10-20 days, ending at some point after–month or 2?.. So, that’s great news it has been 24 years since FDA approval… But not hard studies on 6-8mg/week, for a year straight. Really, nothing even close to that in humans.

I just don’t want something to happen to them in 5-10 years, and something somehow points to Rapamycin–I couldn’t live with myself. We just don’t really have enough definitive results. And mouth sores & pimples & rashes all seem like the immune system is being negatively impacted–something that rarely happens at these lower, more conservative numbers.

Also, I saw a video regarding how the modulation of mTORC1 is key–I believe by a guy named Bryan? Can’t find it. But that made sense to me, and if that’s true, then with such a long half-life of 60 hours, there is still 10-15% remaining in the blood if taken weekly, not allowing the body to ‘live’ with a lower %'s in the body for long enough, IMH (and non-medical mind) Opinion.

But more than all that, I just don’t want to do more harm than good, as it’s not my body, it’s my parents. I will let them know they have the option to increase it beyond this conservative starting point if they want to, and I have shown them the polls on this website showing how 75% take it weekly.

Or, perhaps have them take it every 10 days as a nice ‘happy medium.’ Don’t know.

If anyone has any suggestions on exactly the bare minimum of ‘before tests’ to do, please let me know. At this time, the only thing they have done is a lipid test from 6 months ago during their annual check-up/blood draw. I just don’t know where to start. The Sirolimus Zydus in en route, shipping via India Post - so I probably have 1-2 weeks to figure this all out.

It’d be ideal if there were, like, 3 options outlined that the collective genius on this forum could more or less agree on. For example, 3 lists of pre-test/biomarkers before starting Rapa:

  1. Lower data, bare minimum looking at the most important numbers, mainly for safety, lowest cost
  2. Medium data, little more data, little more cost
  3. High data, tons of data, to get a full-meal-deal on all the potential benefits Rapa may have, costs the most

Then new users can choose their own adventure on how much data they want to log.
Also, where to get these? Do we just go to our family doctors and hand them a list? Or are these tests ordered online? This is where my ignorance shines bright, and something like this would make the ‘next steps’ more obvious for new users.


I am pretty rare in that I do blood tests almost every week, but I am continually changing inputs and so I am particularly interested in identifying whether particular inputs cause particular outcomes.

When it comes to testing, however, what the market offers in any particular jurisdiction is key. Often labs offer panels which are pretty good. You have debates between things like creatinine and cystatin C. Lipid panels vary a bit, but I would try to make sure you have some CRP figures.

However, it is hard to say any more without knowing where you live and even then it is only if you live in the UK that I can make specific suggestions.


I live in the PNW Pacific NorthWest - Seattle, WA area.

It seems like a good plan. Definitely do not do grapefruit juice. That is playing with fire. Fine if it is for you, but I would never do that to my parents. The bioavailability of rapamycin varies greatly among individuals. When you add grapefruit juice, you are just compounding the problem.


Here is my mother’s blood just done a few days ago.
Would this be considered ‘bare minimum’ of tests to be done before starting Rapamycin?

Well, obviously there is not hard and fast rule on what the minimum is. I tend to think that at a minimum you want the information provided by CBC and hsCRP blood tests. This at least allows you to track ongoing biological age testing results using the free Levine Phenotypic Age Calculator (out of Yale), and the Aging.AI biological age calculator. I wouldn’t put a ton of value in the absolute values these calculators provide, but they at least provide a good tracking mechanism to gauge how things are going over time, based on some solid science. I would be more interested in how things change over time, than the absolute numbers.

More details here: A Friendly, Biological Age Reduction Competition?


I think it is great what you are doing. Do keep in mind that I believe it is technically against state and federal laws to give prescription drugs to others (without a medical license). Obviously your parents would not cause you a problem, but one never knows what sort of busy-body person might. Possibly even a family medical doctor if they were irked at losing control of their precious “power of prescription”, or, for instance, the person you gave the Rapamycin to ended up in the ER for something unrelated but reveled they were taking this prescription medication that you gave them. Maybe the ER doctor is legally required to inform the police, who knows. My own policy is to tell only very close family and friends exactly how I have purchased Rapamycin, but to let them buy it themselves.
Being prosecuted is probably an outlier, but I tend to be a bit careful about such things in this crazy world.


I think you may be talking about the following video. Dr. Brian Kennedy covers the mTOR modulation issue in this video here, queued up to the discussion on mTOR modulation:


ad. 1 I would do Levine blood panel markers (google it or search this forum, there is a lot debated about it, here is the link to spreadsheet)

ad. 2 I would take their Aging.AI3.0. blood panel with 19 parameters (you can take the blood test anywhere just use their website to evaluate results, which is free)

additionally I would test lipoproteins, apoB and apoA1 and glucose (especially HbA1c test)
this two would give you a good insight IMO.

Regarding rapamycin dosing, this is highly individual. But there are common wisdoms I gathered reading this forum, podcasts, twitter and research papers is that you should take the maximum dose without unwanted side effects (you need to test this in vivo) and space the doses that your level of rapamycin before next dose is almost zero not to suppress MTORC2 all the time. If you space doses to two weeks, you can take considerably higher dose than weekly.

This post below can give you an idea what experts and rapamycin researchers are taking and their schedule. In any case it is worthwhile monitoring blood biomarkers while taking rapamycin and I would consider testing the trough level of serum rapamycin at the end of dosing period too to see that you are not suppressing MTORC2, but other biomarkers and probably side effects and rise in bacterial infections would be a telltale sign that the dose is too high or spaced too close. One can also take vacations from rapamycin (eg 8-12 weeks on / 4 weeks off) to make sure immune system is not inhibited.


btw how did you get to 6mg/week for your dog? If I am not mistaken the dosage for dog in Dog Aging Project TRIAD Study is roughly 0,15mg/kg… if your dog is around 18-23kg (I googled average weight of golden doodle) you are looking at 2-3mg per week.


You need a good baseline. That’s just the lipids.

Getting at least the phenoage biomarkers is a good idea.

I would say an absolute minimum is a full blood count (FBC) just to ensure that the immune system is in good working order and not already compromised in any way.

My dog weighs 70 lbs, and read 2mg/20lbs once every week, so figured 6mg/week.

You should check your hip mobility. Often these issues are related to lake of internal rotation mobility in the hip. See a good PT.

Why did you decide skipping Rapamycin every second week after reaching the desirable end dose for your parents? Why not to continue with the dose on a weekly basis?

That is some heavy pooch :sweat_smile: 5mg is more correct using 15mg/kg formula I guess.

I want very minimal side effects regarding mTORC2 inhibition. I find this to be a good starting point, “ooching” into this Rapamycin off-label new world.

See sketch below. I understand bioavailability is different from the pill’s mg’s—but this is the idea/trend I’m going for. Shoot holes in it.
