Hello,
As I live in Europe, it’s difficult to obtain rapamycin. I’ve talked to several doctors; they only prescribe it for official indications (kidney transplantation and certain cancers). In the meantime, I’ve discovered another molecule that’s also very interesting: spermidine, which strongly promotes autophagy. Spermidine can be found in wheat germ,cashew nut and Cheddar cheese. That’s what I consume while waiting to find a way to obtain rapamycin.

Help, please!
I’ve started RAPA. My functional med MD rx’d me 2 mg weekly for senescent cell treatment, along with daily NAD+ injections and once-a-month Qualia.
Everything I’ve read here on this site points to a 6 mg dose weekly.
My doc asked me for the research pointing to the 6 mg does. Can anyone point me to “solid evidence” I can send him showing 6 mg dose?

Turn your 2 mg into 6 mg by eating a grapefruit 1-4 hours before you take your Rapamycin. It will boost the effect by 3-3.5X.

That’s how I do it.

Just be careful that none of your other meds are affected by grapefruit juice.

You need the Joan Mannick human clinical trial on improved immune system.

And PEARL human clinical trial of rapamycin … did several dosing tests. 6 mg was optimal.

Hope that helps.

Yes, that helps. I’ll google this unless you have links to them?

A post was split to a new topic: PVC’s (premature ventricular contractions or extra heart beats) and Rapamycin?

Interesting - is this common practice and safe, besides possible interactions w other drugs?

It becomes a problem if you have other medications that interact with grapefruit. Otherwise it’s fine IMHO.

Some medications that can interact with grapefruit include:

  • Cholesterol drugs: Atorvastatin (Lipitor), lovastatin (Mevacor), and simvastatin (Zocor)

  • High blood pressure drugs: Felodipine (Plendil), nifedipine (Procardia), and nisoldipine (Sular)

  • Heart arrhythmia drugs: Amiodarone (Cordarone) and disopyramide (Norpace)

  • Anti-anxiety drugs: Buspirone

  • Blood thinners: Eliquis (apixaban), Plavix (clopidogrel), and Xarelto (rivaroxaban)

  • Antidepressants: Sertraline (Zoloft)

Interesting the vascular effect of rapamycin…
A Japanese team (Ozeki et al. 2025) published a study that may help on this matter. The results were good considering that the vascular anomalies were “intractable”: “Sirolimus treatment for intractable vascular anomalies (SIVA): An open‐label, single‐arm, multicenter, prospective trial”

(…) “Patients received sirolimus tablets or granules (Rapalimus Tablet or Granules, Nobelpharma Co., Ltd., Tokyo, Japan) orally once a day, either after meals or on an empty stomach. The initial dose of oral sirolimus tablets in patients weighing ≥30 kg was 2 mg/day. The starting dose of sirolimus granules in patients ≥30 kg was 0.7 g, equivalent to 1.4 mg of sirolimus, and the initial dose in patients <30 kg was calculated based on the patient’s age and weight (Table [1]. Dose adjustments were made according to sirolimus trough concentrations measured in the second week, to achieve a target concentration of 5–15 ng/mL.”

(I have doubts about rapa intake with or without food)

Hi There

What are your thoughts on Bryan Johnson who recently stopped taking Rapamycin claiming tests prove it will in fact accelerate ageing?

Thoughts?

Thanks

Dino

I am not getting a response from my Indian contact. I would love if someone would share their contact for rapa/sirolimus. We order for both of us close to a years supply.
