Mobile IV therapyRapamycin is the only pharmacological intervention that has consistently extended both median and maximum lifespan in mammals across independent labs. Off-label use in humans for longevity is among the most discussed and most legitimate longevity protocols. Real evaluation, real prescription, careful monitoring.
Rapamycin (sirolimus) was discovered in soil samples from Easter Island in 1972 and developed as an immunosuppressant for organ transplant recipients. It's been used clinically for over 25 years with a well-characterized safety profile.
The longevity story emerged from animal research. The NIA Interventions Testing Program — the gold standard for screening longevity-relevant interventions — has tested rapamycin in three independent labs, in genetically heterogeneous mice, at multiple time points and doses. Rapamycin has consistently extended median lifespan, even when started in old age. Maximum lifespan extension has also been demonstrated. No other pharmacological intervention has this profile of replicated lifespan extension across labs.
For humans, rapamycin is FDA-approved for organ transplant rejection prophylaxis and certain rare conditions. Off-label use for longevity involves much lower doses than transplant medicine — typically 5-6 mg once weekly versus daily dosing for transplant. The lower-dose intermittent protocol appears to capture the longevity-relevant effects while avoiding the immunosuppression that's the concern at daily dosing.
You're already doing the basics (sleep, training, diet, labs) and want to add a pharmacologic intervention.
The age range where mechanistic benefits and safety considerations align best for most candidates.
Rapamycin is for healthy people; not appropriate during active illness, infection, or pregnancy.
Rapamycin requires periodic labs and clinical follow-up. Members who want active engagement are the best fit.
From your first message to your medication arriving at your door — clinician-guided, every step.
A care team member meets with you to understand your goals, medical history, and treatment preferences. The first visit is no-cost and no-commitment — we want you to be confident before moving forward.
Connect by secure video or phone with a U.S.-licensed physician or nurse practitioner who reviews your full picture — labs, prior treatments, current medications, and lifestyle — and decides what is clinically appropriate.
If your clinician determines treatment is right for you, they issue a prescription that goes to a licensed U.S. pharmacy. We coordinate discreet shipping, or you can fill it locally. Follow-up visits are built in.
Rapamycin inhibits the mechanistic target of rapamycin (mTOR), specifically the mTORC1 complex. mTOR is a master regulator of cellular growth, metabolism, and aging. When nutrients and growth signals are abundant, mTOR is active and drives anabolic processes — protein synthesis, cell growth, accumulation of damaged proteins. When nutrients are limited (fasting, caloric restriction), mTOR activity drops and the cell shifts to catabolic processes — autophagy, recycling of damaged proteins and organelles, and stress resistance.
Chronic mTOR activation appears to drive aging. Caloric restriction extends lifespan partly through periodic mTOR inhibition. Rapamycin pharmacologically does what caloric restriction does — inhibits mTOR and triggers the cellular cleanup and stress resistance programs.
The weekly intermittent dosing protocol is designed to trigger transient mTOR inhibition (capturing the longevity-relevant cellular effects) while allowing recovery between doses (avoiding the chronic immunosuppression at daily dosing). Animal data supports this approach; human protocols have evolved to weekly dosing for the same reason.
Your clinician will review every relevant detail with you. Here are the most important points to know up front.
Rapamycin can raise LDL and triglycerides. We monitor and address.
Some members develop mild insulin resistance on rapamycin. CGM monitoring is often part of the protocol.
Mild aphthous ulcers and acneiform rashes are the most common side effects.
Hold rapamycin during active infections and around planned surgery. Your clinician will coordinate.
All medications must be prescribed by a licensed provider based on medical necessity. Treatment is not suitable for everyone. Results may vary.
Typical longevity dosing is 5-6 mg once weekly, taken on a consistent day. Some protocols use higher doses (8-10 mg) weekly or 6 mg every other week; some lower (3 mg). Your clinician personalizes based on goals, tolerance, and lab response.
Take rapamycin on a relatively empty stomach. Grapefruit and grapefruit juice substantially increase blood levels and should be avoided.
Baseline labs include lipid panel, fasting glucose and insulin, CBC, comprehensive metabolic panel, and basic infection screening. Recheck at 8-12 weeks after starting, then at 6 months, then annually if stable.
Many members combine rapamycin with metformin (different mechanism, complementary effect), acarbose (helps the glucose/insulin side effects), and a Mediterranean-style diet. Your clinician builds the protocol around your picture.

"Started rapamycin at 49 after extensive reading and discussion. Two years in: lipids managed with adjustments, mouth ulcers occasional but tolerable, recovery from workouts noticeably better. I treat it as one tool, not a magic bullet."
"My clinician was honest about what rapamycin does and doesn't do. The protocol is more disciplined than I expected — labs, adjustments, occasional dose holds for infections. Worth the work."
"Spent two years reading before starting. Found a clinician who actually knows the literature instead of just selling. Combination of rapamycin + metformin + acarbose has been my protocol for 18 months. Lab markers all moving the right direction."
HealifyNow makes it easy to move forward with confidence. Here are the answers to what people ask us most.
No. Rapamycin is FDA-approved for organ transplant rejection prophylaxis. Use for longevity is off-label, which a licensed clinician can prescribe at their clinical discretion.
Transplant dosing is daily, designed to maintain continuous immunosuppression. Longevity dosing is once weekly, designed to produce transient mTOR inhibition without sustained immunosuppression. The biological effects are different.
Daily high-dose rapamycin (transplant medicine) significantly suppresses immunity. Weekly low-dose rapamycin appears to have minimal effect on routine immune function and may actually enhance certain immune responses in older adults. Your clinician will monitor.
Rapamycin is a longevity intervention, not a symptom medication. Most members don't notice subjective effects, which is consistent with the mechanism. The benefit is biological — observable in labs over time and (theoretically) in long-term outcomes.
Some members report improved recovery from physical or mental load, better immune function with age, and improved skin quality. These reports are anecdotal; the mechanistic benefits are most measurable in animal models.
No. Insurance covers rapamycin for FDA-approved indications. Off-label longevity use is cash-pay. Generic sirolimus is reasonably affordable; pricing is transparent.
Substantial mechanistic and biomarker evidence; lifespan outcomes data is still emerging. The PEARL trial and several ongoing trials are accumulating real human outcomes data. We're transparent that the human evidence is less complete than the animal data.
No. Rapamycin is contraindicated in pregnancy. Discontinue at least 12 weeks before planned conception. Discuss family-planning timing with your clinician.
Many longevity-focused members combine rapamycin with GLP-1 medications. Your clinician will coordinate the protocols.
Over 25 years of clinical use in transplant medicine establishes the daily-dose safety profile. Weekly longevity dosing has less long-term data but the lower exposure profile is reassuring.
Book a free consultation, answer a short health questionnaire, then meet a licensed clinician by secure video or phone. If rapamycin is medically appropriate, your clinician sends the prescription to a licensed U.S. pharmacy and it ships to your door.
Yes. Telehealth prescribing is legal when a licensed clinician evaluates you first. Rapamycin is only prescribed when it's clinically appropriate, and it's filled by a licensed U.S. pharmacy.
Rapamycin pricing is $149/month. Your first consultation is free, you don't need insurance, and your clinician confirms the exact cost before anything is prescribed.
Rapamycin is typically prescribed for healthy adults interested in longevity after screening; rapamycin is FDA-approved for transplant care, so longevity use is off-label and lab-monitored. Your clinician reviews your health history, current medications and goals before deciding whether it's right for you.
Many members meet a clinician within a few days of booking. If rapamycin is prescribed, it ships in discreet packaging and most orders arrive within 2 to 5 business days.
