I have been a daily exerciser for the last 6 years (57 yo male), 50 minutes resistance exercise followed by 3-5 km, Zone 2 run; combined 75 minutes/day. I am plant fat based ketogenic, one meal a day faster, and exercise just before dinner (my single meal), in the fully fasted stateâŚNO issues exercise output/recovery or limiting my cardiovascular/muscular build over this time period (itâs only continuously improved).
I started this IM+IN therapeutic dose rapamycin overlay intervention 6 months ago (arguably the highest trough levels of any healthy human), and pay NO attention to dosing day/exercise, and have not seen ANY effects on my exercise regiment (even though I am clinically iron deficient anemic). I have NO idea (anyone who suggests otherwise or can tease out the perms and combs also has NO clue), the impact of HIGH dose rapamycin/exercise-dose taking/longevity.
Reminder Dr B says Rapamycin + Exercise is âoptimalâ protocol, no qualifications as far as I know.
I do know that being at very high percentile fitness (cardiovascular/skeletal muscle) leads to increased healthspan, and lifespan (proven studies in humans, too many to post), so itâs a non negotiable lifestyle intervention, regardless of my possible pharma interventions like rapamycin, which has never been proven to extend lifespan in healthy humans.
Currently, I am very muscular/toned, 95 percentile VO2maxâŚnever been in better physical shape in my life, including the last 6 months on therapeutic high dose rapamycin. Iâve actually increased my resistance exercise loading reps, not because of any boost from rapamycin or to compensate from, just a personal dial up to further trade residual fat for muscle, to lower my body fat %, whilst keeping total body mass approx same.
Am I blunting key tissue mTOR1 deactivation with this avalanche of sirolimus I am taking with chronic exercise? And thus diluting the longevity benefits? Is it all mTOR1 fundamentally or the gut microbiome remodelling instead? Or autophagy? Measuring autophagy in humans is not yet mainstream. Or is it REALLY mTOR2 as many suspect? Or some other pathway?
The next steps in my journey are to get deeper insights into whatâs happening at tissue levels, trying to measure actual mTOR levels AND gut remodelling.

I would also love to do a radionuclide tagged rapamycin imaging analysisâŚand observe the tissue/organ biodistribution of the drug, especially how much if any crossing into the CNS/brain. A study was done in rats which showed IM was far superior to oral in elevating tissue levels of rapamycin, dose equivalency.
