Long-form research on longevity, regenerative medicine and everyday wellness — updated weekly.
What to Expect at Your First Longevity Medicine Consultation
A first longevity consultation looks less like a standard check-up and more like a full systems review. Here is what actually happens, what gets tested, and what to ask before committing.
Hormone Replacement Therapy and Heart Health: Separating Myth From Evidence
A single 2002 headline reshaped how a generation of women and their doctors thought about hormone therapy. Two decades of reanalysis tell a considerably more nuanced story.
Micronutrient Testing: Building a Truly Personalized Supplement Stack
Most supplement routines are assembled from podcasts and guesswork. Testing replaces the guessing with data — and often removes more products than it adds.
Peptide Therapy for Cognitive Longevity: Semax, Selank and Nootropic Peptides
These compounds circulate widely in online longevity communities with confident claims attached. The evidence behind them is thinner and narrower than the discussion suggests.
Rapamycin vs. Metformin for Longevity: Comparing the Evidence
Both are decades-old prescription drugs now discussed as longevity interventions. They work through different pathways, carry different risks, and have very different bodies of evidence behind them.
Heart Rate Variability: A Daily Window Into Your Biological Age
The tiny variations between heartbeats reveal how well your nervous system adapts to stress. It is one of the few longevity-relevant markers you can measure every morning at no additional cost.
Collagen Peptides for Skin Longevity: What the Evidence Supports
Oral collagen is one of the few supplements with randomized trial support for skin outcomes. It is also one of the most oversold. Here is where the line between the two sits.
Sleep Apnea and Accelerated Aging: The Hidden Longevity Risk
Most people with obstructive sleep apnea do not know they have it. For a longevity protocol, few undiagnosed conditions undermine progress as thoroughly or as silently.
Genetic Testing for Longevity: How Pharmacogenomics Shapes Personalized Protocols
Two people can take the same dose of the same drug and end up with completely different blood levels. Pharmacogenomics explains part of why — and it is a very different thing from the disease-risk reports sold direct to consumers.
Preserving Muscle Mass on GLP-1 Weight Loss Medications
A meaningful share of the weight lost on GLP-1 medications is lean tissue, not fat. Protein intake, resistance training and body composition tracking are what separate a good outcome from a smaller, weaker version of the same body.
Time-Restricted Eating vs. Alternate-Day Fasting: Which Fits a Longevity Protocol?
Both protocols restrict when you eat rather than dictating what. They share mechanisms but differ sharply in intensity, evidence base and how many people can actually sustain them.
Grip Strength as a Longevity Biomarker: What the Research Shows
A cheap handheld device predicts long-term health outcomes about as well as some expensive panels. Grip strength is not magic — it is a window into whole-body muscle function and neurological integrity.
Epigenetic Clocks Explained: DunedinPACE vs. Horvath vs. GrimAge
Three of the best-known epigenetic clocks answer three different questions: how old your tissue looks, how fast you are aging right now, and how likely you are to develop disease. Choosing the wrong one makes the result meaningless.
Continuous Glucose Monitoring for Non-Diabetics: What Your Numbers Really Mean
A CGM gives a metabolically healthy person more glucose data in two weeks than a lifetime of annual checkups. Here is how to read it — ranges, variability, confounders — without turning useful signal into anxiety.
TRT vs. Peptide Secretagogues: Comparing Two Approaches to Hormonal Optimization
One replaces a hormone from outside. The other asks the body to make more of its own. They act on different axes, with different reversibility, different fertility implications and different risk profiles — and both require medical supervision.
Fisetin and Quercetin as Senolytics: Do Natural Compounds Clear Zombie Cells?
Two plant flavonoids sold as supplements are being studied as senolytics. The preclinical biology is genuinely interesting; the human evidence is early, the doses are far above dietary intake, and the marketing has run well ahead of both.
PRP vs. Cortisone Injections for Knee Osteoarthritis: Which Lasts Longer?
Cortisone works fast and fades fast. PRP works slowly and may hold longer. Here is how the two injections differ in mechanism, evidence, risk and cost — and how to decide which fits your knee.
Exosome Therapy for Hair Loss: What the Early Evidence Shows
Exosomes are being marketed aggressively for hair restoration. The biology is genuinely interesting, the early clinical data is small and preliminary, and the gap between those two facts is where most patients get lost.
NAD+ IV Therapy vs. Oral NAD+ Supplements: What Actually Raises Your Levels
Intravenous NAD+ and oral precursors like NMN and NR take completely different routes to the same molecule. Here is what the evidence says about absorption, tolerability, cost and what each route can realistically deliver.
GLP-1 Peptides and Longevity: Beyond Weight Loss
Semaglutide and tirzepatide are being discussed as longevity tools, not just weight loss drugs. Here is what the mechanisms suggest, what the trials have shown, and the muscle loss risk that deserves far more attention.
