TL;DR: Rapamycin, an FDA-approved immunosuppressant, is now being prescribed off-label by longevity clinics to slow biological aging by inhibiting the mTOR pathway. You can obtain it through a specialized clinic after extensive bloodwork, but it is not a DIY supplement—dosing is weekly, low-dose, and requires continuous monitoring.
Step 1: Verify You Are a Candidate
Longevity clinics typically reserve rapamycin for adults aged 40–70 with no active infections, uncontrolled diabetes, or recent surgeries. You’ll undergo a comprehensive panel: fasting insulin, lipid profile, liver enzymes, CBC, and inflammatory markers (CRP, IL-6). If you have a history of mouth ulcers, poor wound healing, or take strong CYP3A4 inhibitors (like certain antifungals), the clinic may reject you. Bring your full medication list.

Step 2: Choose a Reputable Longevity Clinic
Not all “anti-aging” clinics are equal. Look for one affiliated with academic research (e.g., clinics run by physicians who publish in aging journals) or members of the American Academy of Anti-Aging Medicine. Ask directly: “Do you follow the Interventions Testing Program protocols?” Avoid clinics that sell proprietary blends—rapamycin must be prescribed as a pure generic (sirolimus) from a licensed pharmacy. Expect an initial consult fee of $300–$600, plus $50–$150 per monthly follow-up.
Step 3: Start with a Low, Weekly Dose
The standard longevity protocol is NOT daily. Most clinics start at 5 mg once per week, taken orally with food (to reduce GI upset). Some ultra-conservative prescribers begin at 3 mg, while aggressive protocols go up to 10 mg weekly. Never split doses daily. Take it on the same day each week, preferably in the morning, and skip if you have a fever or active infection. Do not take with grapefruit juice—it spikes blood levels dangerously.
Step 4: Monitor Side Effects and Blood Levels
After 4 weeks, you’ll get a trough level blood test (drawn 24 hours after your dose). Target range for longevity is 5–15 ng/mL—far lower than transplant levels (4–12 ng/mL is similar, but transplant uses daily dosing). Watch for canker sores, diarrhea, or elevated cholesterol (rapamycin raises LDL in ~30% of users). Your doctor may add a statin or CoQ10. Check kidney function (creatinine) every 3 months. If you develop a non-healing wound, stop and call immediately.
Step 5: Cycle or Pause Strategically
Many clinics recommend a “pulse” approach: 6 weeks on, 2 weeks off, to reduce immune suppression. Others use continuous low-dose for 6 months, then a 1-month holiday. Never combine rapamycin with live vaccines (e.g., shingles shot) within 2 weeks. For surgeries, stop 2 weeks prior. Some patients also use metformin or acarbose alongside, but only under physician direction—this combo can cause hypoglycemia.
Step 6: Track Outcome Biomarkers
Success is measured by changes in epigenetic clocks (e.g., PhenoAge), grip strength, gait speed, and HbA1c. Expect a 10–20% reduction in inflammatory cytokines within 3–6 months. Do not expect immediate energy changes—rapamycin often causes temporary fatigue. Re-evaluate every 6 months; if no biomarker improvement, the clinic may stop the prescription.
FAQ
Q: Is rapamycin safe for healthy people without a prescription?
A: No—rapamycin is a prescription drug with serious risks (lung inflammation, infections, impaired glucose tolerance). Do not buy it from research chemical sites. Only a licensed clinic can monitor your blood levels and adjust doses safely.
Q: How long do I need to take rapamycin to see anti-aging benefits?
A: Evidence from animal studies suggests
