mTOR/Autophagy Pulse Protocol
Risk: ModerateThe Attia/ITP-data-backed longevity duo — weekly rapamycin pulses inhibit mTOR (the most consistently life-extending intervention in mammals), while daily metformin activates AMPK and improves glucose handling. Two distinct anti-aging pathways with complementary mechanisms and decades of human data.
Composition: 1 Metabolic Peptide · 1 Longevity
Overview
The mTOR/Autophagy Pulse Protocol is the stack for users laser-focused on proven, actionable longevity interventions. Weekly rapamycin pulses take direct aim at mTOR — the pathway with the most robust evidence for lifespan extension in mammals. Daily metformin activates AMPK, sharpening insulin sensitivity and tilting energy metabolism toward repair rather than storage. If you want the Attia-style, ITP-data-backed core with actual data behind increased median and maximum lifespan, this is the protocol. It's not a muscle-growth or performance-driven stack — but for healthspan, cellular cleanup, and metabolic resilience, it's about as close as you'll get to a plug-and-play anti-aging backbone.
Why this stack works
Metformin (daily, low-dose) is here for AMPK activation — triggering cellular energy sensing, blunting hepatic glucose output, and generally shifting the metabolic state toward 'repair and maintain' rather than 'grow and store.' It's cheap, well-tolerated, and brings a mountain of metabolic and cardiovascular risk modification data. Rapamycin takes the other side: weekly pulses hit mTORC1 hard, driving a spike in autophagy and cellular cleaning, then letting mTORC2 recover, which avoids most of the transplant-dose side effects. The weekly cadence is key — you want the benefits of transient mTORC1 inhibition (autophagy, immune function, possible SIRT1 upregulation) without chronic metabolic derailment. The combination targets both arms of the pro-longevity axis: suppression of nutrient sensing (mTOR) and real-time energy stress signaling (AMPK). They're clean together — no major interactions, simple division of labor, and both stack well with most other interventions (e.g., low-dose PDE5 for vascular, GLP-1s if pushing deeper into body composition).

| Week | Compound | Dose | Frequency | Notes |
|---|---|---|---|---|
| 1-24 | Metformin | 500 mg | 1-2x/day | Start with 500 mg daily, increase to 500 mg twice daily as tolerated |
- Only increase to 2x/day (1000 mg total) if GI side effects are minimal for at least 1 week at 500 mg.
- Dose with or after food to minimize GI upset.
- Supplement vitamin B12 (200–500 mcg/day) if running metformin for longer than 8–12 weeks — check levels after 3 months.
- Avoid excessive alcohol intake (both drugs increase risk of lactic acidosis with very heavy drinking).
- If also running GH, SGLT2 inhibitors, or GLP-1s, monitor for additive effects on glucose lowering.
- If endurance or strength is a priority (hypertrophy training), take metformin post-workout, not pre, to minimize interference with acute anabolic signaling.
| Week | Compound | Dose | Frequency | Notes |
|---|---|---|---|---|
| 1-24 | Rapamycin | 4–6 mg | 1x/week | Take as a single oral pulse, same day each week |
- Choose a weekday you can adhere to every week — consistency matters for the metabolic patterning of mTOR signaling.
- Take rapamycin in the morning after a light meal for best absorption; avoid grapefruit juice (CYP3A4 inhibitor).
- If you're on statins, potent CYP3A4 inhibitors/inducers, or other major meds, check for drug interactions (rapamycin is sensitive here).
- Do not schedule heavy resistance training or major hypertrophy work within 24–48 hours post-rapamycin; let mTOR suppression clear before training for optimal adaptation.
- Run fasting lipids and glucose every 8–12 weeks; rapamycin can slightly raise LDL or glucose in some users, usually manageable by adjusting dose or cadence.

Conclusion
This stack gives you the best-evidenced longevity play: clean mTORC1 inhibition plus daily AMPK activation. If you want the effective, minimalist route — with tight protocols and manageably low risk — this is it. Run it as written, keep an eye on lipids and fasting glucose, and you're in that small minority actually doing something real for lifespan.
