2025 Longevity Medicine Recap: What Accelerated, What Broke
#76 Weekly Longevity Medicine Intelligence
Hey Doc,
This morning, I woke up reflecting, not just on my own year, but on ours as an industry. I’m grateful for the evolution. What changed since December 2024:
For us: we created a summit in Cannes. Launched a certification program. Built a research network. Went from 250 physicians to 600+ across 50 countries.
For the industry: i believed we matured as an industry… understanding that innovation and responsibility must grow together.
I truly believe that we underestimate what we can achieve in a year.
2025 taught us that lesson at scale. Here’s what actually happened.

PS: this is picture of my happy place.
Each week, I try to explore one idea that could advance longevity medicine and hopefully support physicians in bringing it to life.
Longevity Medicine 2025: What Accelerated, What Broke
When we started building in 2021, most people were still asking: “What is longevity medicine, exactly?” 2025 was the year longevity medicine escaped the clinic and entered society. Here’s what actually happened.
What Accelerated
1. Longevity became pop culture
Longevity moved from niche science to mainstream conversation. From Netflix to podcasts to beauty and fashion, longevity became an aspiration, not a stigma.
2. Longevity moved beyond clinics
Longevity showed up in gyms, hotels, corporate wellness, and homes.
Medicalized or not, consumers now access multi-tier solutions with very uneven evidence.
3. Clinics exploded
Longevity clinics multiplied fast, often faster than standards.
Access and visibility grew globally, but scale clearly came before standardization.
4. Biomarkers as a commodity
Blood tests, clocks, CGMs, and scans became affordable and mainstream.
Testing got easy; interpretation did not. Data moved faster than clinical judgment.
5. Startups bet on Longevity
Companies finally treated longevity as a real category. 2025 brought longevity EMRs, supplement, skin health, test, wearables, and full tech stacks for longevity care.
6. Education scaled fast
Conferences, certifications, and courses exploded. Demand for knowledge outpaced the field’s ability to ensure depth, rigor, and competence.
What Broke
7. The black market expanded
Peptides and hormones flooded grey markets as demand outpaced regulation. “Research only” became a label, not a safety standard.
8. Polypharmacy became normalized
Patients stacked GLP-1s, peptides, hormones, and supplements freely. Personalization often blurred into complexity without clear evidence or stopping rules.
9. Followers replaced credentials
Longevity became content, and authority fragmented. Reach sometimes mattered more than outcomes, and patients often heard influencers first.
10. The workforce gap became obvious
Doctors were asked to practice longevity medicine without being trained for it.
The bottleneck isn’t innovation: it’s education, judgment, and clinical standards.
The Real Takeaway of 2025
Longevity medicine didn’t fail in 2025. It scaled faster than its foundations. 2026 will be about standards, training, and restraint or let the loudest voices define it.
Next week: my 2026 predictions.

Every week, the Longevity Docs WhatsApp group feels like a front-row seat to the future of medicine. Here’s what had doctors buzzing:
The Consent Reckoning: When Optimization Meets Real Risk
(GLP-1s, peptides, stacking - and the patients we don’t expect to see in ICU)
One of the most sobering conversations this week came from physicians working in acute care.
Two “fit and well” patients.
Two life-threatening presentations.
Both under longevity-style optimization protocols.
The discussion wasn’t about blaming innovation it was about consent, contraindications, and responsibility in a field that’s moving faster than long-term data.
What doctors flagged:
Rare but real GLP-1 complications (bowel obstruction, ischemia, pancreatitis), especially in patients with prior GI surgery or adhesions
Polypharmacy by stacking peptides, hormones, and metabolic agents without fully understanding interactions
Patients who look healthy but have hidden risk factors (hematocrit, motility, vascular tone, arrhythmia risk)
The hardest truth shared:
“It’s not sexy, but long consent processes may be the most important intervention we have.”
Several clinicians emphasized visible risk disclosure, structured consent, and slowing down escalation, especially in the “well” patient where benefit margins are narrow.
Key Takeaway:
Longevity medicine will be judged not by its upside but by how it handles downside.
If we don’t lead on consent, contraindications, and restraint, others will define the narrative for us.
Peptide Regulation Shockwave: Demand Is Exploding, Standards Are Not
A short question: “Thoughts on the proposed peptide law?” opened a much bigger conversation.
Doctors quickly moved from curiosity to concern:
Supplier trust collapsing: multiple clinicians expressed hard stops on commonly used vendors
Increased awareness that many suppliers operate in a gray regulatory zone, often labeled “for research only”
Growing fear that poorly regulated access could trigger overcorrection by lawmakers
Several voices were blunt:
“Don’t use them.”
“Nope.”
Not because peptides have no future but because credibility requires discipline.
Key Takeaway: Peptides are no longer niche. They’re mainstream and that’s exactly why the bar must rise. The opportunity for physicians is not broader access, but clear standards around sourcing, indication, consent, and restraint before regulation is imposed from the outside.
Orthobiologics vs Surgery: “Don’t Treat the MRI, Treat the Patient”
A shoulder MRI case sparked one of the most practical, grounded clinical threads of the week.
The patient had a tear.
The MRI looked bad.
Surgery was being pushed.
But experienced clinicians slowed the conversation down.
What emerged:
Many partial rotator cuff tears heal with time, PT, and proper load management
PRP and biologics are best understood as modulating inflammatory imbalance, not magically “regrowing cartilage”
Imaging often overcalls severity, especially when not correlated with symptoms or ROM
Dynamic ultrasound, in expert hands, can outperform MRI for functional assessment
One line captured the spirit of the discussion:
“The most important technology is the doctor who sits between the imaging and the patient.”
Key Takeaway: Longevity medicine isn’t anti-surgery, it’s anti-reflex. Patients need clinicians who can interpret imaging through function, symptoms, and trajectory, not outsource judgment to a report.

Toward precision longevity: aging interventions in the single-cell atlas era
This Frontiers mini-review reveals why longevity interventions work unevenly: different cell types age differently. Single-cell atlases are emerging as the missing layer that explains why the same intervention benefits some tissues but not others. The future of longevity medicine is precision aging, cell-by-cell, not one-protocol-fits-all.
Exercise attenuates the hallmarks of aging: Novel perspectives
Exercise is still the most validated longevity intervention we have, especially for older adults. This review argues exercise may favorably influence all 14 hallmarks of aging, but admits a key gap: much of the “hallmarks” mechanistic evidence is still animal-heavy, and we need better human studies (tissue-specific effects, mtDNA, proteostasis/autophagy, nutrient sensing, ECM remodeling, telomeres).
Every week, I track funding, FDA approvals, product launches, and breakthrough announcements shaping longevity medicine.

Newsletter Disclaimer:
Excellent synthesis of where longevity medicine sits right now. The distinction between scaling and foundation-building is key because growth without standards eventually becomes its own liability. The consent conversation around GLP-1 complications and polypharmacy stacking is something I've seen firsthand in ER settings where patients show up with unxpected metabolic cascades nobody anticipated. The gap between consumer demand and clinical training is only widening and that's where trust erodes fast.
