I have tested various rapamycin protocols including weekly (5, 6, and 10 mg dose schedules), biweekly (13 mg) and alternating weekly (6/13mg) to optimize rejuvenation and limit side effects.

The headline is broadly defensible, but the qualifications matter. Effect sizes vary by population, the strongest claims rest on shorter trials, and credible voices push back on how it's typically framed.

Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
The "high risk" framing here is the right call. I've had three patients ask about rapa this month and none of them grasped the immunosuppression tradeoff until I walked them through it.
The PEARL trial framing in the dossier is the clearest writeup I've seen for a non-specialist. Worth linking from the AMA pages too.
I'm on 6mg/week, year two. Tracking IL-6, fasting glucose, lipids. Happy to share the spreadsheet if Whalespan wants longitudinal user data.
The dosing variance across the advocate camp is staggering. 3mg, 5mg, 8mg, biweekly, weekly… brief is right that "monitor or specialist only" is the responsible read.

Blood Rapamycin levels: 90 min: 26.5 ng/mL 4.1 days: 2.5 ng/mL 13 days: not detected
Previously maintained a weekly Rapamycin dosing protocol of 6mg weekly.
We tried protocols including five of these pills per week. We tried a protocol of six pills one week and 13 pills the next week. We tried 13 and 13.
Rapamycin extends median and maximum lifespan in mice across multiple lab strains and dosing protocols.
Rapamycin will extend human lifespan by 5+ years at standard weekly dosing.
Weekly rapamycin dosing in healthy adults shows favorable safety and immune markers in early observational data.
Chronic low-dose rapamycin imposes an immune trade-off that outweighs the longevity hypothesis for most healthy adults.
mTORC1 inhibition is the mechanistic backbone for rapamycin's healthspan effects in mammals.
The PEARL trial showed an acceptable 48-week safety profile in healthy adults on weekly rapamycin.
