The Claim

Intermittent weekly dosing of 5 mg or 10 mg compounded rapamycin over 48 weeks is likely safe in healthy adults aged 50 to 85 years, with no significant differences in serious adverse events or laboratory abnormalities compared to placebo, suggesting its potential for long-term use in normative aging.

Description

In plain English

Taking rapamycin once a week for a year might be safe for healthy older adults, with no more side effects than a sugar pill — so it could be a candidate for slowing normal aging.

See the scientific wording

Intermittent weekly dosing of 5 mg or 10 mg compounded rapamycin for 48 weeks is probably safe in healthy adults aged 50–85, with no significant differences in serious adverse events or laboratory abnormalities compared to placebo, supporting its potential for long-term use in normative aging.

What the research says

1 study
  1. Study: Influence of rapamycin on safety and healthspan metrics after one year: PEARL trial results

    The study tested the same rapamycin doses and schedule as in the claim and found no more side effects than with a placebo, so it supports the idea that this treatment is safe for older adults over a year.
