My 10‑week low‑dose rapamycin + spermidine trial – what I noticed

Posted by chemist_daily in Longevity & Anti-Aging - 1 points, 4 comments.

I’ve been curious about the rapamycin + spermidine combo for a while, so I decided to try it for ten weeks just to see how it felt. I kept rapamycin at the low end of the usual research range – about 4 mg once a week – and took spermidine around 2 mg each morning with breakfast. fwiw I didn’t change anything else in my routine, same sleep schedule, same workouts, same diet.

During the first couple weeks I noticed a slight bump in morning energy, nothing dramatic, but I did feel a bit less sluggish after my afternoon shift at the clinic. Around week four my skin seemed a tad smoother, especially around the eyes, and I woke up feeling a little more refreshed, though I can’t rule out placebo or just getting used to a new supplement rhythm.

By week eight the effects plateaued; energy stayed steady, no major changes in recovery after lifting, and I didn’t see any new wrinkles disappear. I did get a mild dry mouth once or twice after rapamycin, which went away after a day.

If I did it again I’d probably add a simple liver support like TUDCA just to be safe, and I’d get baseline bloodwork before starting. Nothing felt like a miracle, but the stack was easy to tolerate and gave me a subtle sense of “cleaner” cellular turnover. Would love to hear if anyone else has tried a similar length and what they tracked.

• priya_gains: That’s a solid observation. In my own low‑dose rapamycin trial, 4 mg once a week with 2 mg spermidine, I saw a similar early lift in daytime alertness, but it faded after about six weeks. I didn’t notice any change in post‑workout recovery or a visible smoothing of skin. I did, however, experience dry mouth and a bit of fatigue on the day after dosing, which settled with hydration. I now pair it with a gentle liver support like TUDCA and reset my baseline labs three months before each run‑throu
• chemist_daily: I did feel that dry mouth right after my first 4 mg dose, aroundfrage the first week. It kicked in about 20‑30 minutes after injection and usually died out by mid‑afternoon if I drank water. I haven’t tried TUDCA yet, but I might. How long after your dosing do you need to see the labs? ⚡
• aspiring_codes: I didn’t notice any dry mouth at all on my first week. I did feel a slight fatigue theStations day after dosing, but it faded with extra fluids and a light snack. If it showed up, it was just a few hours and not a persistent dryness. 🔁
• chemist_daily: Thanks for the heads‑up! I did feel a mild dip in energy a couple of days after my first dosing week, but staying hydrated helped. Have you noticed any difference in your caffeine tolerance since starting? Also curious if you added a small protein snack – I tried a banana and whey and that seemed to smooth things out.
