I put off my appointment at Human Longevity (HLI) in South San Francisco for months. Having completed most of the tests they offer individually over many years, I finally decided to go to HLI to see if the integrated experience was worth the markup. When it finally happened, I gave up half a day to a litany of tests— blood work, MRI, body composition, and every other longevity acronym you could invent.

What am I actually paying for?

Walking into HLI felt like checking into a small luxury hotel, but one that’s been plopped into the unlikely setting of an industrial suburb. The start of my $8,000 visit was a warm greeting and a trip to my private suite, equipped with its own TV, shower, bathroom, coffee, and snacks. 

HLI was founded in 2013 by Craig Venter, Peter Diamandis, and Robert Hariri—a heavy-hitting roster of longevity evangelists whose backgrounds span genetics, stem cells, and entrepreneurship.

It’s part of a crowded market for full head-to-toe testing, including other ventures from Diamandis, such as Fountain Life–which he founded alongside Tony Robbins–which offers annual memberships starting at around $10,500 and going up to $85,000. Trusted institutions like Mayo Clinic and Cleveland Clinic have run executive health programs for decades.

I was impressed by the comprehensiveness and care of the HLI service, with a detailed agenda of the day’s events. Specialists walked me through each test, explaining their process step by step. A doctor stopped in briefly.

I was treated with dignity— a standard that is not always guaranteed in medicine.

The results arrived over the next several days and were integrated into a dashboard complete with links and explanations. It looked clean, but there was too much medical jargon.

…‘Dumb it down’ is what I always preach to the medical establishment.

I ran the findings through AI for second and third opinions, and sent the reports to my doctors at NYU, including my cardiologist, to verify the conclusions. It all checked out. And since my visit, HLI has introduced its own internal AI bot to interpret results. 

Once I got past the marble and the warm towels, the real value of the HLI experience became clear.

Their product isn't the luxury experience, the machines, or the tests— it's the assembly. Behind the scenes, HLI decides which instruments to buy, whose analytics to license, and how to combine the results into a clear picture of how you're aging.

Curation is central to the HLI pitch. You are not just buying scans and blood tests; you are buying the premise that your genome and biomarkers reveal a lot about your health, and that you deserve the best tools and experts to collect and distill this information, integrating it with MRIs and bloodwork.

The other source of value was the human follow-up. That consultation was genuinely useful, as my doctor had reviewed all of my data with a heart specialist before our call. I took his recommendations and notes back to my own care team to create a game plan.

It reversed the normal doctor-visit routine, where you go in to see your doctor for an ache or pain, and then they refer you out for testing. Days later, the doctor calls you or emails you the results. Here, the doctor had everything in place, and the aim was prevention and detection.

I like the HLI sequence, but it got me wondering: what would all of this cost à la carte? Do I really need an $8,000 package?

Breaking Down the À La Carte Option

You probably don’t need an $8000 package from providers like HLI to get the same technical tests. If you are disciplined enough to assemble the pieces yourself, the individual components may cost a fraction of the price.

  • Blood panel: A standard 36-marker blood panel runs around $100. Function Health charges $365 a year for roughly 160 lab markers across two draws. 

  • Whole-body MRI: Prices have dropped significantly in recent years. For example, a company called Ezra (acquired by Function in 2025) offers head-to-pelvis scans for $999; SimonMed regularly runs promotions near $899; and Prenuvo holds the high end with full-body scans at $2,499 and less, offering other membership tiers.

But is the DIY version worth it?

It might be—depending entirely on your budget and how much you dislike playing your own care coordinator. What the premium price actually covers is whole-genome sequencing, concierge coordination, and a unified report from a trusted team. 

The downsides to longevity testing

Still, major medical boards generally do not recommend whole-body screening for asymptomatic individuals, and standard insurance plans typically do not cover it.

One of the primary medical concerns is also not going to be the out-of-pocket cost, but incidental findings—benign anomalies ("incidentalomas") that trigger cascade testing, invasive biopsies, and months of unnecessary anxiety. 

That’s why my primary doc always says, “Brad, you are over-testing.”

I disagree: the more I know about my body, the better.

Plus, I do not fit the definition of an asymptomatic healthy adult in this context. I have a known cardiac history and thirty years of medical records.

For me, this was not an exploratory fishing expedition. HLI used targeted monitoring to connect the dots of my health, recommending changes to my heart meds and sleep patterns.

The Bottom Line: Is the full experience worth it?

Was I over-tested? Probably. But was it useful for my specific situation? Yes. I look at these tests like maintaining an older car with a history of mechanical issues: periodic, comprehensive diagnostic checks help keep track of what needs fixing.

It remains expensive and largely out of reach for most people, but accessibility is shifting quickly, and prices are coming down as demand for longevity heats up.

The best part about it is that I can combine HLI's biomarker and DNA data with my 30-year history into a single, searchable AI record that any physician can pull up in an emergency.

If you have existing health complexities and want a clear picture of current risks, an integrated assessment can be a reasonable investment—the $8,000 covers data collection. However, it does not cover any long-term solutions. 

Taking action still depends on having a doctor who can read the fine print and on the follow-through work you do yourself. Face it, we are on our own as advocates for our health.

Disclosure: Human Longevity (HLI) is a paying sponsor of the Livelong Women’s Health SummitTM in New York this September, where its executive chairman, Wei-Wu He, is a keynote speaker. However, I paid full price for this visit out of my own pocket. No one at HLI reviewed or approved this piece before publication.
