The Longevity Services Landscape in 2026
Longevity services now range from concierge medical practices to subscription blood testing, telehealth prescribing, and clinics selling IV infusions, peptide protocols and hyperbaric sessions. The challenge for consumers is telling evidence-based medicine from expensive wellness theater.
This guide compares the main service categories: what each offers, what is backed by evidence, and what you can do yourself with free tools. No affiliate links, no referral fees, no sponsored placements.
The short answer: much of what premium services sell, such as choosing tests and designing a protocol, you can do yourself with self-ordered labs and free resources. What you can't replicate is prescription access, imaging and the judgment of a physician who knows your history, and that is where paid services earn their fee.
Tier 1: Concierge Longevity Medicine
What it includes: Comprehensive annual diagnostics (bloodwork, DEXA, cardiac imaging, full-body MRI, cognitive testing, VO2 max testing), personalized protocols designed by a physician who knows your complete medical history, prescription access, quarterly follow-ups, and often direct physician access via text/email.
Who offers it: Physician-led concierge practices, from nationally known longevity clinics to local practices. Fees vary widely and are often not published, so ask for the full annual cost in writing.
What's genuinely valuable: The physician relationship is the irreplaceable element. A doctor who understands longevity science, knows your history, and can integrate multiple data streams into personalized recommendations provides genuine value that no tool can replicate. Advanced imaging (whole-body MRI, cardiac CT) requires clinical facilities.
What you're overpaying for: Much of the blood testing can be self-ordered for far less. The protocols that follow often apply the same evidence-based frameworks covered in our free tools, and premium hospitality is pleasant but doesn't improve health outcomes.
DIY equivalent: Use our Blood Panel Builder to choose a panel to self-order, Lab Interpreter for analysis, Protocol Builder for protocol design, and our Biomarker Guide for reference. For imaging and prescriptions, use the telehealth services in Tier 3 or your own doctor.
Tier 2: Testing Platforms
These services provide blood testing with digital dashboards, biomarker tracking, and AI-generated recommendations. They do not prescribe medications or provide physician consultations (with some exceptions).
What subscription testing offers
Subscription platforms bundle blood panels drawn at a commercial lab, a results dashboard and clinician or AI-generated commentary for an annual fee; Function Health, for example, sends members to Quest Diagnostics, which runs the tests. The panels can be broad and the convenience is real, but you are paying a premium for packaging tests you could order yourself.
Where they fall short
Proprietary "biological age" scores are rarely validated in independent published studies, recommendations can be generic, and some services are tied to a founder's own supplement line, a conflict of interest worth noticing. Compare what you get against a self-ordered panel before you subscribe.
The DIY alternative
Self-order through Quest or LabCorp directly. Use our Blood Panel Builder to select exactly the right tests for your profile. Use our Lab Interpreter for longevity-optimized analysis. Track in our Dashboard. You lose the polished interface but gain the ability to customize exactly what you test.
Tier 3: Longevity Telehealth
These are the services that genuinely add value that tools cannot replicate: physician access and prescription medications.
AgelessRx
A telehealth service that prescribes longevity-oriented medications, including rapamycin and metformin off-label. Its research team ran PEARL, a 48-week double-blind trial of low-dose weekly rapamycin in healthy older adults: side effects were similar to placebo, the main outcome (visceral fat) did not change, and women on 10 mg gained lean mass and reported less pain.1
When this is worth it: If you want rapamycin, off-label metformin or hormone therapy, a longevity telehealth provider is the practical route, with baseline tests and monitoring. Many primary care physicians are reluctant to prescribe rapamycin for longevity. Compare consultation and monitoring costs before you commit.
Red Flags: What to Watch For
Selling proprietary supplements. If a longevity clinic or practitioner designs a protocol that coincidentally requires purchasing their branded supplements, the conflict of interest is obvious. Independent practitioners who recommend specific products (not their own) are more trustworthy.
IV therapy as a primary offering. IV NAD+, glutathione and vitamin C drips have little trial evidence of benefit for healthy adults, and oral intake covers most micronutrient needs at a fraction of the cost. IV therapy has a role in specific clinical situations but is often marketed beyond its evidence.
Promising specific lifespan extensions. No practitioner can credibly promise to extend your lifespan by X years. Claims like "add 10 years to your life" are marketing, not medicine. Honest practitioners talk about risk reduction, biomarker optimization, and healthspan improvement — not guaranteed lifespan numbers.
Peptide protocols without monitoring. BPC-157, TB-500, GHK-Cu, and other peptides are increasingly popular but lack robust human clinical trial data. Clinics prescribing peptide cocktails without adequate baseline testing, monitoring, and informed consent about the evidence gaps are operating beyond the evidence.
Excessive testing frequency. Quarterly comprehensive blood panels are rarely necessary for healthy adults. Most markers change slowly enough that testing once or twice a year shows the trend; more frequent testing generates revenue but rarely changes what you would do.
The strongest trust signal: A practitioner who acknowledges what they don't know, cites specific studies, discusses evidence limitations, and doesn't sell products through their practice. The best longevity physicians sound a lot like a well-informed friend — not a salesperson.

Frequently Asked Questions
It depends on what you need. Test selection and protocol design you can largely do yourself with self-ordered labs and our free tools. For prescriptions such as rapamycin, off-label metformin or hormone therapy, a longevity telehealth provider is the practical route. Comprehensive one-to-one physician care is valuable if you can afford it; ask for all costs in writing.
Selling proprietary supplements as part of the protocol, recommending expensive IV therapies without strong evidence, prescribing peptides without adequate monitoring, promising specific lifespan extensions, and aggressive upselling on testing packages you don't need. Independent providers who don't sell products are generally more trustworthy.
Some primary care physicians will prescribe metformin off-label for longevity if you discuss the evidence with them. Rapamycin is harder, because many doctors are uncomfortable prescribing it off-label. Longevity telehealth services such as AgelessRx prescribe it with monitoring.
Look for a board-certified physician who explains the evidence behind each test and treatment, says plainly when the evidence is thin, and doesn't sell supplements, IV drips or peptides through the practice. A willingness to test ApoB and discuss prevention beyond standard screening is a good sign. Membership in an anti-aging or functional-medicine association is not, on its own, a sign of evidence-based care.
