Rapamycin dosage for longevity what protocols people use

This page is informational. It describes, in general terms, how people talk about rapamycin dosing for longevity — not a plan for you to follow. For the risks that make dosing so consequential, read rapamycin side effects by dose and schedule; for the full evidence base, see the main rapamycin guide.

Is there a "correct" longevity dose?

No. The optimal anti-ageing dose and schedule for rapamycin have not been established in humans, and reliable biomarkers to confirm you are hitting a longevity target rather than an immunosuppressive one are still lacking.^[2] Anyone presenting a precise "longevity dose" as settled science is overstating what is known.

Optimal dose not established

What approach do people generally describe?

The commonly discussed off-label pattern is intermittent rather than daily dosing — a low amount taken on a weekly rhythm, spaced out deliberately. The reasoning is that occasional low exposure may nudge the mTOR pathway toward maintenance while avoiding the continuous, heavy immune suppression seen at transplant doses.^[2] We are describing the shape of the approach, not endorsing specific amounts.

What did the PEARL trial actually test?

The PEARL trial examined low-dose intermittent rapamycin in healthy adults and found it well tolerated over roughly a year, with only modest biomarker changes.^[1] That tells us a low intermittent schedule is feasible and tolerable in the short term — it does not tell us the "right" dose, and it did not demonstrate that participants aged more slowly or lived longer.

Why self-dosing is the wrong move

Rapamycin is a prescription immunosuppressant, the longevity dose is genuinely unsettled, and there is no easy at-home way to verify you are dosing safely. Those three facts together are why this should never be a do-it-yourself experiment. If you are seriously interested, the appropriate path is a licensed clinician or regulated telehealth provider who can weigh your individual situation.

Where the field is heading

Larger and longer human trials are underway, and their whole purpose is to move dosing from educated guesswork toward evidence. Until they report, treat any specific longevity dose as provisional. You can follow the broader science across the Rapamycin.store library as it develops.

Frequently asked questions

Is there an established rapamycin dose for longevity?

No. There is no proven optimal anti-ageing dose or schedule for rapamycin. What people discuss are off-label patterns, not a validated protocol, and the right dose is exactly what ongoing research is still trying to work out.

How often do people take rapamycin for longevity?

The commonly discussed off-label approach is intermittent rather than daily — typically a low dose taken weekly, on the theory that spacing doses reduces immune suppression. This is a general pattern people describe, not a recommendation, and it should only be done under clinician supervision.

Why is intermittent dosing preferred over daily?

The idea is that occasional low doses may nudge the mTOR pathway toward maintenance without the continuous, heavy immune suppression seen at transplant doses. Whether this reliably delivers an anti-ageing effect in humans is not yet proven.

Can I work out my own rapamycin dose?

This is not something to self-administer. Rapamycin is a prescription immunosuppressant, the longevity dose is unsettled, and there are no simple at-home ways to confirm you are dosing safely. Any dosing decision belongs with a licensed clinician.

What dose did the PEARL trial use?

PEARL tested low-dose intermittent rapamycin in healthy adults and found it well tolerated over about a year. We describe it qualitatively here rather than as a dosing instruction — the trial studied tolerability and biomarkers, not a proven longevity dose.
