Lab-guided longevity care, online
Start with a free 5–10 minute call, get a baseline lab panel and receive a written plan from a licensed U.S. clinician that is rechecked against your numbers over time.
Free to book. You pay only if you go ahead with treatment.
Your clinician orders a baseline panel chosen for your situation, writes a prioritized plan and rechecks it against your numbers around 90 days.
Every suggestion is labeled by evidence tier, from proven basics like blood pressure and sleep to early options such as compounded NAD+, which is not FDA-approved.
If an off-label medicine such as rapamycin, metformin or acarbose fits your plan, your clinician can send it to a licensed U.S. pharmacy.
Membership starts at $99 a month for clinician visits, lab reviews and plan updates. No insurance or referral is needed; labs and medicines are priced separately.
Choose phone or video when you book. In about 5–10 minutes, a licensed clinician hears your goals, reviews your history and current medicines, and tells you honestly whether the program makes sense.
Your clinician orders the tests that fit your goals, often lipids including ApoB and Lp(a), HbA1c and fasting insulin, kidney and liver function, thyroid and inflammation markers. You visit a nearby draw site.
Your clinician explains the results and writes a plan ranked by priority: lifestyle targets, any follow-up testing and prescriptions only where they judge treatment appropriate.
Most members repeat key labs around 90 days, then at longer intervals once things are stable. The plan changes when your numbers or your goals change.
Many members have no diagnosis at all. They want to find rising blood sugar, cholesterol or inflammation markers early, while small changes still have room to work.
If a parent or sibling developed heart disease, type 2 diabetes or dementia, earlier and more detailed testing can help you and your clinician set priorities.
If you have been researching rapamycin, metformin or NAD+, a clinician can walk through what the evidence shows, what it doesn't and whether any of it suits your situation.
The program runs on repeat lab work. If seeing your ApoB, HbA1c or hs-CRP move over time keeps you motivated, the format fits well.
If you have active cancer, a recent heart attack or stroke or a complex chronic illness, your care belongs with your own doctors and specialists. The program is also not for anyone who is pregnant.
| Tier | Examples | Evidence |
|---|---|---|
| Tier 1: foundations | Blood pressure, lipids, glucose, activity, sleep and tobacco | Strongest human evidence |
| Tier 2: off-label prescriptions | Rapamycin, metformin and acarbose | Being studied for aging; human data still limited |
| Tier 3: compounded options | NAD+ and glutathione | Not FDA-approved; limited human data for aging |
Healthy aging research asks a practical question: which habits, tests and medicines help people stay strong, clear-headed and free of chronic disease for longer? A few answers are well established, such as lowering high LDL cholesterol and blood pressure, staying active and sleeping enough. Others, including the use of drugs like rapamycin, metformin and acarbose for aging itself, are still being studied and are prescribed off-label, meaning outside the uses the FDA has reviewed.
Our program puts those two groups of evidence in order. A licensed U.S. clinician looks at your history and a baseline lab panel, then writes a plan that starts with the measures most likely to matter for you. Medication is one option among several, never the default, and it is only prescribed if your clinician decides it is appropriate.
We will not promise you extra years. What we can offer is a clear picture of where you stand today, a plan you understand and repeat testing so you and your clinician can see whether anything is actually changing.
It helps to sort longevity options into tiers. The strongest human evidence supports managing cardiovascular risk factors, keeping blood sugar in a healthy range, regular exercise including strength work, good sleep and not smoking. These are not glamorous, but they come first in every plan we write.
The next tier includes prescription drugs already approved for other conditions that researchers are studying for aging. In the National Institute on Aging's Interventions Testing Program, rapamycin and acarbose extended lifespan in mice tested at several sites. Mouse results do not prove the same benefit in people. A 48-week trial of low-dose weekly rapamycin in adults aged 50 to 85, called PEARL, found it was relatively well tolerated but did not change its main measure, visceral fat.
A third tier includes compounded products such as NAD+ and glutathione. These are prepared by licensed U.S. compounding pharmacies, are not FDA-approved, and have limited human data for aging. Your clinician will tell you plainly which tier any suggestion falls into.
Membership starts at $99 per month and covers your clinician's time: visits, reviewing your labs, writing and updating your plan, and handling prescriptions. Lab panels are priced separately, and so is any medication you are prescribed. Your clinician confirms costs before you commit to anything.
Because most longevity care is self-pay, you do not need insurance or a referral. Many members keep their regular primary care doctor and share their results with them.
Off-label prescribing is legal and common, but it means the FDA has not reviewed the drug for that purpose. Every medication in a longevity plan carries its own risks, and your clinician will go through them with you before you start.
Independently licensed U.S. physicians supervise every treatment we offer.

Book a free consultationIt is preventive care aimed at extending the years you spend in good health, sometimes called healthspan. In practice it means detailed testing, early action on risk factors and, in some cases, off-label medications that researchers are studying for aging. It does not stop or reverse aging.
The program starts at $99 per month for clinician care, plan updates and prescriptions. Lab panels and medications are billed separately, and your clinician confirms those costs before anything is ordered. The first consultation is free.
No. The program is self-pay, so you do not need insurance, a referral or prior authorization. You can still share your results with your regular doctor.
It depends on your goals and history. Common choices include a full lipid panel with ApoB and Lp(a), HbA1c and fasting insulin, kidney and liver markers, thyroid tests, vitamin levels and hs-CRP for inflammation. You give blood at a draw site near you.
Not necessarily. Many members never take a longevity medication and focus on lifestyle and standard risk factors. A clinician only prescribes when they decide the likely benefit outweighs the risk for you.
Yes. U.S. clinicians may prescribe an FDA-approved drug for a purpose outside its label when they judge it medically appropriate. The FDA has not reviewed that use, which is why the evidence and risks need an honest discussion first.
About 5–10 minutes by phone or video, whichever you choose when booking. It is enough for your clinician to understand your goals, review your history and decide which labs to order.
Many members recheck key markers around 90 days after starting a change, then less often once results are stable. Your clinician sets the schedule based on what you are taking and what your numbers show.
No one can promise that. Lowering proven risk factors such as high LDL and high blood pressure reduces the chance of heart disease and stroke. Whether drugs like rapamycin extend human lifespan is not yet known.
We do not run a supplement store. If your clinician thinks a supplement is worth trying, they will explain why and you can buy it wherever you like.
It depends. People with stable, well-managed conditions can sometimes join with their own doctor's input. Active cancer, recent heart attack or stroke and complex illness need specialist care first.
They are compounded products some members add to their plan. They are prepared by licensed U.S. compounding pharmacies, are not FDA-approved, and have limited human evidence for aging. They are priced separately and only prescribed if your clinician considers them appropriate.
Your plan and any ongoing costs are explained before you start. If you want to stop, contact the care team, and your clinician can advise how to come off any medication safely.
