In March 2024, a New York longevity clinic called Modern Age closed its doors with almost no warning. It had raised $33 million from serious investors — Oak HC/FT, GV (Google’s venture arm), Juxtapose. It had glowing press coverage. It had paying members who’d handed over $1,500 for an “Aging Wellness Assessment” and, in some cases, prepaid for ongoing care. Then the money ran out, and it was gone — patients redirected to other providers, medical records routed through a third-party records company, no clear public accounting of what happened to anyone’s prepaid balance.
Five months later it reopened under new ownership, at one of its two original locations, run by a different doctor with a different company attached. Most people who searched “best longevity clinics in the US” during that window never heard any of this. The listicles that show up for that search are, almost without exception, written by people who get paid when you click through to book — which is a structural reason none of them mention the thing that actually happened to real members of a real, well-funded clinic in this exact category.
We don’t sell longevity clinic memberships, and we have no paid or affiliate relationship with anyone in this article. This is a real comparison of ten of the best-known, most-searched longevity clinics operating in the US in 2026 — what they cost, what they actually include, what independent evidence exists for each one’s core claims, and the parts of this industry that the marketing pages leave out.
TL;DR
- 2026 pricing across this comparison spans $199/year (Superpower) to roughly $100,000/year (Peter Attia’s own practice, Early Medical) — a difference of more than 500 times for services that market themselves in nearly identical language.
- Modern Age, a well-funded ($33M raised) NYC longevity clinic, shut down abruptly in March 2024 and reopened five months later under different ownership — a real precedent for the financial risk of prepaying an annual or multi-year membership at a young, venture-funded company.
- Cenegenics, the oldest brand here (founded 1997), built much of its early reputation on testosterone and growth hormone for “age-related” decline — a use the FDA has never approved and the Endocrine Society’s own clinical guideline specifically does not support for men without a diagnosed condition.
- Function Health was valued at $2.5 billion in November 2025, even as a Forbes analysis the same month warned its business model looks like “engagement engines, not economic engines” — pointing to two price cuts already (from $499 to $365/year) under competitive pressure.
- No clinic in this comparison has published independent, peer-reviewed evidence that its specific membership extends lifespan or reduces disease compared with standard preventive care.
Quick Verdict
- Best if you don’t live near a major city: Wild Health — genomics-based precision medicine delivered entirely by telehealth, nationwide, from a home base in Lexington, Kentucky.
- Best low-cost entry point: Function Health, $365/year for 100+ standard blood biomarkers with physician review — though its pricing has already changed twice in its first two years.
- Best for the deepest single-visit diagnostics: Biograph, co-founded by Peter Attia — full-body MRI, coronary CT angiography, and a multi-cancer blood test, in San Francisco and New York, from $7,500/year.
- Longest operating history: Cenegenics, running since 1997 with 20+ US locations — also the clinic in this comparison with the most direct, documented controversy over hormone prescribing.
- Most exclusive and expensive: Early Medical, Peter Attia’s personal concierge practice — fewer than 75 patients total, close to $100,000/year, currently closed to new patients.
- The cautionary tale everyone should read before paying upfront: Modern Age — proof that “well-funded” and “well-reviewed” don’t guarantee a longevity clinic will still exist next year.
- Who should pause before joining any of these: anyone assuming a sleek website and a “founded by a famous doctor” story is a substitute for asking what happens to your money if the company doesn’t make it.

We’ve already published a full, evidence-graded comparison of Fountain Life, Human Longevity, Superpower, and Next Health — read it here. This article focuses on six clinics that comparison doesn’t cover, chosen because each represents a genuinely different model within the same broad category: a founder-led diagnostics startup (Biograph), a low-cost blood-testing membership with a celebrity-adjacent founder (Function Health), a telehealth-only genomics practice (Wild Health), the industry’s oldest and most hormone-focused brand (Cenegenics), the single most exclusive practice in the space (Early Medical), and the clinic that actually shut down (Modern Age) — a case none of the affiliate-driven “best of” lists in this category seem to want to talk about.
Biograph
Biograph is the newest and most attention-grabbing name in this list, launched from stealth in February 2025 by two people whose names alone generate headlines: Peter Attia, the physician and author of Outlive whose own concierge practice (Early Medical, covered below) is separately one of the most expensive in the country, and John Hering, the cybersecurity entrepreneur (Lookout) turned Silicon Valley investor best known more recently as one of Elon Musk’s financial backers through his role at Vy Capital.
Pricing. Two tiers: Core at $7,500/year (20+ assessments, including a full-body MRI, comprehensive blood panel, DEXA scan, and VO2 max testing, plus physician review) and Black at $15,000/year (30+ assessments, adding coronary CT angiography, a low-dose lung CT, a multi-cancer early detection blood test, a brain health assessment, at-home sleep testing, and continuous glucose monitoring).
Locations. Two, so far: the flagship in the San Francisco Bay Area, and a second clinic in New York City.
What’s genuinely different here. Attia co-founding a second, more accessible company while his own practice remains closed to new patients and priced near six figures is a notable structural fact worth knowing before you assume “Attia-affiliated” means “the same thing as being Attia’s patient.” It isn’t — Biograph is a separate company with its own physicians, and its marketing describes itself as “the world’s most advanced preventive health and diagnostics clinic,” a claim that, like similar language from Fountain Life and Human Longevity, is a company’s own positioning rather than an independently verified ranking.
What they don’t publish. As a company launched in 2025, Biograph has no independent, peer-reviewed outcomes data yet — no clinic this new could. That’s not a knock specific to Biograph; it applies to every company on this list founded in the last five years.
ScanGlean evidence grade: Grade B for the individual diagnostic tools used across both tiers (whole-body MRI, coronary CT angiography, DEXA, and standard bloodwork are all independently validated technologies for their approved uses). Grade C for the claim that bundling them into an annual membership, as marketed, improves outcomes over standard, guideline-based care — a claim no company in this article has published data to support.
Function Health
Function Health is the closest thing to a household name in consumer longevity testing right now, largely on the strength of its cofounder: Dr. Mark Hyman, a physician, bestselling author, and one of the most recognizable faces in the wellness-media world, alongside co-founders Jonathan Swerdlin, Daniel Swerdlin, Pranitha Patil, Mike Nemke, and Seth Weisfeld.
Pricing. Membership currently runs $365/year, down from an original $499 — its second price cut in roughly two years, following a promotional period that briefly offered two years for $499 ($250/year effective). This covers 100+ (the company has said up to 160+ across two annual draws) lab biomarkers, physician review, and an app-based results interface. Some additional testing — full thyroid panels beyond TSH, heavy metals, expanded gut markers — costs $49-149 extra on top of the base membership.
Scale. Function Health raised a $300 million round in November 2025, led by Redpoint Ventures, at a $2.5 billion valuation — a genuinely enormous number for a two-year-old blood-testing subscription business, and one that reflects real investor conviction in the category, not just Function specifically.
What critics say. A November 2025 Forbes analysis, published the same month as that funding round, raised a pointed structural concern: consumer lab-testing companies like Function are, in the author’s words, building “engagement engines, not economic engines,” because the underlying lab work is commoditized (partners like Quest Diagnostics and LabCorp capture much of the economics) and pricing keeps falling under competitive pressure — Function’s two cuts, and rival Superpower’s drop to $199/year, are both cited as evidence of a “classic race to the bottom.” The same piece states plainly: “Without peer-reviewed evidence, these remain marketing claims,” referring to the proprietary interpretation layers these companies build on top of standard lab results.
ScanGlean evidence grade: Grade B for the underlying lab biomarkers themselves — these are standard, validated tests, the same kind ordered by any primary care physician. Grade C for Function’s proprietary “optimal range” flags and AI-generated health insights layered on top, which have not been independently validated in published research.
Wild Health
Wild Health is structurally the odd one out in this comparison — not because of what it tests, but because of how you access it. Every other clinic on this list requires showing up somewhere. Wild Health is telehealth-only, nationwide, from day one.
Founders and location. Started by Dr. Matt Dawson and Dr. Mike Mallin, two emergency-room physicians who began seeing patients through their own networks before scaling into a full telehealth company. It’s based in Lexington, Kentucky, and delivers precision medicine — built around genetic testing, extensive lab panels, and its own proprietary algorithm called Clarity — to patients across the country by video visit, without requiring anyone to travel to a physical clinic.
Pricing. The Peak membership costs $25,000/year and includes comprehensive genetic analysis, a 200-biomarker lab panel, unlimited physician visits, unlimited follow-up labs, unlimited health coaching, and a biometric tracking device. A higher Elite tier (not publicly priced — “inquire”) adds direct cell-phone access to a concierge doctor, on-demand care team access, unlimited advanced testing and imaging, and in-person add-ons like acupuncture and hyperbaric oxygen, capped at 50 patients per physician.
What makes it genuinely useful for some readers. If you don’t live within reach of San Francisco, New York, Miami, or Las Vegas — where most of the clinics on this list and the last operate — Wild Health is one of the only options here that doesn’t require relocating or flying in periodically. That accessibility is a real, structural advantage, separate from any claim about outcomes.
What’s unproven. Wild Health’s Clarity algorithm — which combines genetics, labs, microbiome, and lifestyle data into personalized recommendations — is proprietary and has not, as far as we could find, been validated in independent, peer-reviewed research as improving outcomes compared to standard precision-medicine practice (genetic counseling plus guideline-based care).
ScanGlean evidence grade: Grade B for the individual components (SNP-based genetic testing and standard lab biomarkers are established technologies). Grade C for the proprietary Clarity algorithm’s specific recommendations, which have not been independently validated in published research.
Cenegenics
Cenegenics is the elder of this group by a wide margin — founded in 1997 by Dr. Alan Mintz and CEO John E. Adams, years before “longevity clinic” was a category anyone was raising venture capital for. It’s also the one clinic here with a genuinely documented, long-running controversy attached to its core offering.
Pricing. A “Performance Health Assessment” — an all-day evaluation including a physical exam, DEXA scan, VO2 max testing, cardiovascular imaging, cognitive assessment, and a two-hour physician consultation — costs $4,495 to $13,000 depending on testing scope. After that, members pay ongoing monthly fees for nutraceuticals and therapies ($350-600) plus a program fee for physician access and lab work ($550-750), totaling roughly $14,000-$21,000 in a typical annual cycle.
Scale. Cenegenics operates 20+ locations across the US (Atlanta, Beverly Hills, Chicago, Dallas, Denver, Houston, Las Vegas, Miami, New York, Phoenix, San Francisco, and more), plus international locations in Mexico City, Bogotá, and São Paulo, and says it has worked with 49,000+ patients since founding — a company-reported figure, not independently audited.
The hormone therapy question. Cenegenics built much of its early public profile — including extensive 2000s-era media coverage in outlets like CBS News and Bloomberg — around testosterone and human growth hormone prescribing for “age-related” hormonal decline in men who did not have a diagnosed medical condition causing low hormone levels. This is a use the FDA has never approved: testosterone products are approved specifically for men with hypogonadism caused by a defined medical condition, not for general aging, athletic performance, or appearance. The Endocrine Society’s own clinical practice guideline explicitly limits testosterone therapy recommendations to men with confirmed hypogonadism and has noted that terms like “age-related” or “functional” hypogonadism blur the line between a treatable condition and normal aging in a way that complicates informed consent. A 2021 review in the Journal of the Endocrine Society, titled plainly “Testosterone Therapy for the Treatment of Age-Related Hypogonadism: Risks with Uncertain Benefits,” lays out the state of the evidence — real, documented cardiovascular risk signals, and genuinely uncertain benefit for this specific population.
What’s changed. Cenegenics today markets itself around a much broader 270+ biomarker panel and general “age management,” and any clinic — including mainstream hospital systems — can legally prescribe testosterone off-label with appropriate monitoring. The company says it monitors relevant safety markers (PSA, hematocrit, cholesterol, blood pressure) during hormone therapy. The point isn’t that Cenegenics is uniquely unsafe; it’s that this specific, long-running practice within its model is one where the FDA’s approval status and a major medical society’s guideline diverge meaningfully from what the “age management” marketing implies.
ScanGlean evidence grade: Grade B for the standard diagnostic components (DEXA, VO2 max, standard bloodwork are validated tools). Grade C specifically for testosterone/growth hormone prescribing for age-related, non-diagnosed hormonal decline — the use the FDA has not approved and the Endocrine Society’s guideline does not support.
Early Medical (Peter Attia’s Own Practice)
This is not a clinic you’re likely to be able to join, but it belongs in a genuinely useful comparison because it’s the anchor at the extreme end of the price range, and because so much confusion online conflates it with Biograph (covered above), a different company Attia co-founded.
What it is. Early Medical is Peter Attia’s personal concierge medical practice, based in Austin, Texas. According to CBS News’ 60 Minutes reporting, the practice sees fewer than 75 patients total — an unusually small number by design, meant to allow extended, highly personalized primary care — and charges a fee the report described as “much closer to $100,000 than $500,000” a year, not including lab work and specialized testing, which add several thousand dollars more annually. Other reporting has cited a broader range of roughly $50,000 to $120,000/year depending on scope.
What’s included. A two-day intensive initial evaluation covering muscle mass, cardiorespiratory fitness and VO2 max testing, DEXA body composition, full-body MRI, and APOE gene testing for Alzheimer’s risk, followed by an ongoing, highly individualized exercise (roughly 10 hours/week prescribed across multiple modalities) and nutrition program (targeting around 1 gram of protein per pound of body weight daily for many patients).
Access. Currently closed to new patients, with only a waitlist available.
What critics say. The same 60 Minutes report notes that “physicians, including a respected professor of public health,” were skeptical of aspects of Attia’s regimen, and quotes the American College of Radiology’s position that “there is no documented evidence that total body screening is cost-efficient or effective in prolonging life” — a criticism aimed at whole-body MRI screening broadly, which Early Medical includes as a standard part of its evaluation.
ScanGlean evidence grade: Grade B for the individual diagnostic and training components, most of which are established (VO2 max testing, DEXA, and genetic risk testing are all real, validated tools). Grade C for whole-body MRI screening specifically, where the American College of Radiology’s own position is that cost-efficiency and life-extension benefit remain undocumented — a criticism from within radiology’s own professional body, not from a competitor.
Modern Age — The One That Closed, and What It Teaches You
Every other section in this article, and most “best longevity clinic” content you’ll find elsewhere, treats these companies as stable, ongoing businesses you’re choosing between. Modern Age is the reminder that this isn’t always true, and it’s worth understanding in detail precisely because almost nothing else covering this topic mentions it.
What happened. Modern Age launched in 2022 as a New York-based “aging wellness” clinic, offering an in-depth Aging Wellness Assessment (around $1,500) plus ongoing services including GLP-1 weight-loss medication management. It raised $33 million in outside capital, including a $27 million Series A in October 2021 led by Oak HC/FT, with participation from GV (Google’s venture arm) and Juxtapose — serious, credible institutional investors, not a fly-by-night operation. In March 2024, founder Melissa Eamer announced the company could not raise the capital needed to continue operating, and it closed. Public reporting on the closure describes the company referring existing patients to other providers and routing medical records access through a third-party records company (Cariend) — but does not document a clear, public process for refunding prepaid assessments, credits, or any unused portion of a membership.
What happened next. Five months later, in August 2024, Modern Age reopened — but only at its Upper East Side location (the Flatiron location did not reopen), under new ownership: Dr. Ali Rashan, founder and CEO of a separate company called ClearMD, purchased Modern Age’s intellectual property and became its new CEO, with the relaunched clinic working closely with ClearMD for care beyond Modern Age’s original scope.
Why this matters for every other clinic in this article. Modern Age wasn’t an obscure operation — it had the funding, the press coverage, and the founder profile that, on paper, look identical to several other companies in this comparison. The lesson isn’t “avoid longevity clinics.” It’s that a polished website, strong initial funding, and enthusiastic press coverage are not evidence that a company will still exist, in the same form, by the time your annual membership is up for renewal — and that almost none of the “best longevity clinics” content elsewhere on the internet will tell you that, because most of it is written to get you to click through and buy, not to protect you if the company doesn’t make it.
ScanGlean evidence grade: Not applicable — Modern Age is included here as a case study in financial and structural risk, not as an active recommendation.
How to Vet a US Longevity Clinic Before You Pay
None of these companies are regulated the way a hospital or an insurance-billed medical practice is. There’s no equivalent of FDIC insurance for a prepaid wellness membership. A few concrete questions, worth asking before you hand over a five-figure annual fee:
- What happens to my money if the company closes? Ask this directly, in writing, before joining — not as a hypothetical, but citing Modern Age specifically if you want a straight answer instead of a deflection. Most companies in this space have never had to answer this question publicly.
- How is the company funded, and by whom? A newer, still-venture-funded company (most of the clinics in this article, except Cenegenics) is inherently earlier in its business lifecycle than an older, profitable one — that’s not automatically disqualifying, but it’s relevant risk information most marketing pages don’t volunteer.
- Which specific tests are included in the price, and which cost extra? Add-on testing (thyroid panels, heavy metals, expanded imaging) is common across this category and can meaningfully change your real annual cost.
- Is any specific claim backed by independent, peer-reviewed evidence — or only by the company’s own materials? As this article and our companion comparisons show, that distinction matters enormously and is rarely made clear in a sales conversation.
- Would a physician with no financial stake in your membership order the same tests, at the same frequency, for someone with your age, sex, and risk profile? If the honest answer is no, that’s worth knowing before you pay, not after.
Cost Reality
- The headline number is rarely the total number. Cenegenics’ quoted evaluation fee is separate from ongoing monthly costs. Function Health’s base membership excludes several add-on panels. Biograph and Wild Health both have a lower “entry” tier and a meaningfully more expensive concierge tier for the same underlying company.
- Pricing in this category changes fast, and mostly downward for the low-cost tier. Function Health has cut its price twice (from $499 to $365, with a promotional period as low as $250/year); Superpower cut from $499 to $199 within seven months of launch. That’s good news for buyers in the short term, but it’s also evidence — per the Forbes analysis cited above — that these businesses are still finding a sustainable price point, which carries its own kind of risk for anyone relying on the service long-term.
- The high-cost tier is a different market entirely. Early Medical’s near-$100,000/year practice and Fountain Life’s application-only $85,000/year tier aren’t really competing with Function Health’s $365/year membership on any dimension except the word “longevity” appearing on both companies’ homepages.
- Insurance doesn’t meaningfully offset any of this. As with every clinic in our companion comparison of Fountain Life, Human Longevity, Superpower, and Next Health, none of the six clinics newly covered here bill insurance for the core membership fee.
The Bottom Line
There is no single “best longevity clinic in the US” — there’s a wide spread of genuinely different products wearing similar marketing language. Biograph and Fountain Life sell deep, in-person diagnostics to people who can get to San Francisco, New York, or a handful of other cities. Function Health and Superpower sell accessible, low-cost blood testing to nearly anyone with a Quest or LabCorp near them. Wild Health sells the same genomics-and-labs model by telehealth to people who can’t or don’t want to travel. Cenegenics sells a decades-old age-management model with a real, documented hormone-therapy controversy attached to part of it. Early Medical sells extreme exclusivity to a few dozen people who can pay six figures a year. And Modern Age sells a lesson that applies to every name on this list: none of these companies has existed long enough, or published enough independent data, to be a safe assumption rather than a bet.
That’s not a reason to avoid this category. It’s a reason to ask the same kind of direct questions about a $15,000 annual membership that you’d ask about any other major purchase from a young company — and to remember that most of what ranks for “best longevity clinics in the US” was written by someone with a financial reason not to bring any of this up.
Frequently Asked Questions
What are the best longevity clinics in the US?
There’s no single best one — it depends what you’re buying. Biograph (co-founded by Peter Attia) and Fountain Life lead on in-person diagnostic depth (full-body MRI, coronary CT angiography). Function Health and Superpower lead on low-cost, nationwide blood testing. Wild Health leads on telehealth accessibility outside major cities. Cenegenics has the longest operating history (since 1997). Early Medical, Peter Attia’s own practice, is the most exclusive and expensive, currently closed to new patients. None has independent, peer-reviewed evidence that its membership extends lifespan.
How much does a longevity clinic cost in the US in 2026?
Real 2026 pricing spans an enormous range: Function Health starts at $365/year for blood testing alone, Superpower is $199-399/year, Biograph runs $7,500-$15,000/year, Wild Health’s Peak tier is $25,000/year, Cenegenics totals roughly $14,000-$21,000/year after the first year, Fountain Life’s top tier is $85,000/year by application, and Peter Attia’s own practice, Early Medical, runs close to $100,000/year for fewer than 75 patients total.
What happens to my membership if a longevity clinic shuts down?
It’s a real risk, not a hypothetical one. Modern Age, a New York longevity clinic that had raised $33 million from investors including Oak HC/FT and GV, abruptly closed in March 2024, telling patients only that it would help refer them elsewhere. Public reporting on the closure did not document a clear refund process for prepaid assessments or credits. It reopened five months later under new ownership (Dr. Ali Rashan of ClearMD), with only one of its original two locations. Before paying annually or multi-year upfront, ask directly what happens to your money if the company closes — most longevity clinics are young, venture-funded companies, not decades-old institutions.
Is Function Health worth it?
The underlying product — 100+ standard lab biomarkers with physician review — is a well-established, individually valid form of testing, and at $365/year it’s one of the cheapest ways to get it. What’s less proven is the proprietary interpretation layer (Function’s AI-generated insights and “optimal range” flags), which hasn’t been independently validated in published research. A November 2025 Forbes analysis also flagged the business model itself as a concern: Function has already cut its price twice under competitive pressure from Superpower, and most of the underlying lab economics go to partners like Quest Diagnostics and LabCorp, not Function.
Can I actually become a patient of Peter Attia?
Not easily. Attia’s own concierge practice, Early Medical, sees fewer than 75 patients total, according to CBS News’ 60 Minutes reporting, and costs a figure the report described as “much closer to $100,000 than $500,000” a year — and it is currently closed to new patients, with only a waitlist available. Attia is also a co-founder of Biograph, a separate, more accessible (if still expensive) diagnostics clinic in San Francisco and New York, at $7,500-$15,000/year — a meaningfully different product from his personal practice.
Is Cenegenics legit, and is testosterone therapy for anti-aging safe?
Cenegenics is a real, operating company — not a scam — founded in 1997 and still running 20+ US locations. But its historical emphasis on testosterone and growth hormone for “age-related” decline in men without a diagnosed medical condition is a genuinely contested practice: the FDA has never approved testosterone therapy for anti-aging or age-related use, and the Endocrine Society’s clinical guideline specifically limits testosterone therapy to men with a documented diagnosis of hypogonadism, not general aging. A 2021 review in the Journal of the Endocrine Society titled “Risks with Uncertain Benefits” summarizes the state of the evidence for this specific use.
Do US longevity clinics take insurance?
Almost never for the membership fee itself. All the clinics in this comparison are cash-pay, membership- or program-based models. Individual tests ordered through a longevity clinic — a coronary calcium score, standard bloodwork, a diagnostic (not screening) MRI — may be separately billable to insurance if medically indicated, but the concierge or membership fee is treated as an out-of-pocket wellness expense in essentially every case.
What should I ask before joining any US longevity clinic?
Ask what happens to your money if the company shuts down mid-membership — get it in writing, not a verbal assurance. Ask which specific tests are included versus billed separately. Ask whether any part of the price is refundable, and under what conditions. Ask how long the company has been operating and whether it’s still raising venture funding to stay solvent (a sign of a still-unproven business model, not necessarily a red flag on its own, but relevant to know). And ask whether a physician with no financial stake in your membership would order the same tests for someone with your age, sex, and risk profile.
