The Science of Age-less Living

In this episode of The Science of Age-less Living, Dr. Ethan Hausman-Marquis unpacks Humanin — a molecule with one of the most remarkable origin stories in longevity science. Discovered in 2001 in the surviving neurons of an Alzheimer's-affected brain, Humanin turned out to be encoded not in our nuclear DNA but inside the mitochondrial genome, making it the founding member of an entirely new class...

SS-31 — also known as elamipretide — occupies a category no other compound in this series can claim: it is the first mitochondria-targeted therapy ever to receive FDA approval. In this episode, Dr. Ethan traces the compound from its accidental discovery in a Weill Cornell pharmacology lab through to its September 2025 accelerated approval for Barth syndrome, unpacking the biology of cardiolipin —...

Pinealon is one of the least discussed compounds in mainstream longevity medicine — and that obscurity is itself worth examining. Derived from pineal gland tissue and developed within a serious, decades-long Russian bioregulatory peptide research programme, it sits at the intersection of two of the most compelling areas in ageing biology: the decline of the pineal gland as a master regulator of ci...

SEMAX is one of the most discussed cognitive compounds in the longevity and nootropic world — and arguably one of the most poorly understood. In this episode, Dr. Ethan does what this series always does: follows the science wherever it leads, without the hype and without the dismissiveness. The story of SEMAX starts not in a supplement company's marketing department, but in a Soviet government res...

GHK-Cu — glycine-histidine-lysine complexed with copper — is one of the most structurally simple compounds in this series and one of the most mechanistically interesting. It is a tripeptide: three amino acids, naturally present in human plasma, saliva, and urine, with plasma concentrations that fall from roughly 200 nanograms per millilitre in young adults to near-undetectable levels by the time m...

In the mid-1990s, antiretroviral therapy was transforming HIV from a death sentence into a chronic condition — and creating an unexpected syndrome in its wake. Patients on the new combinations were developing visceral fat accumulation, peripheral fat loss, dyslipidaemia, and a measurably blunted growth hormone rhythm. A small Canadian biotech in Montréal saw the lever. Native GHRH had a half-life...

In this episode of The Science of Age-less Living, Dr. Ethan explores Thymosin Alpha-1, one of the most clinically studied and widely prescribed peptides in the world. Originally isolated from the thymus gland in the 1970s, Thymosin Alpha-1 has evolved from an obscure immune peptide into a prescription immunomodulator used in more than 35 countries. We examine the remarkable history of its discove...

Klotho was discovered in 1997 when a disrupted gene caused mice to develop every hallmark of premature ageing within weeks — osteoporosis, arteriosclerosis, muscle wasting, cognitive decline — and die at a fraction of their expected lifespan. The inverse experiment extended lifespan by twenty to thirty percent. The protein was named after Clotho, the Greek Fate who spins the thread of life. It rem...

This is the first episode in a new series: the Top 20 Peptides. Over twenty episodes, Dr. Ethan Hausman-Marquis examines the most researched compounds in longevity and regenerative medicine — the real biochemistry, the honest evidence base, and the regulatory context behind each one. No hype, no discount codes. Just the science. We start with BPC-157. Derived from a naturally occurring sequence in...

In this episode of The Science of Age-less Living , Dr. Ethan Hausman-Marquis reveals why many people using peptide therapy only achieve partial results — and how an easy, science-backed fix can unlock the missing 30–40% of their potential. He explains that peptides (such as BPC-157, CJC-1295/Ipamorelin, Thymosin Alpha-1, and collagen peptides) are powerful signaling molecules that tell your body...

Most longevity medicine is built on guesswork, trends, and short-term thinking. In this episode, Dr. Ethan Hausman-Marquis breaks down why that approach fails—and what actually drives measurable, long-term results. Inside The Catalyst Clinic, longevity is treated as a structured clinical system, not a collection of supplements or peptides. From strict patient selection to deep data collection, adv...

In this episode of The Science of Age-less Living, Dr. Ethan dives deep into the fascinating world of peptides — the tiny but powerful molecular messengers that play a central role in how we age. You’ll discover how peptides are encoded in your genes, follow the remarkable cellular factory process of transcription and translation that builds them, and learn how these short chains of amino acids ac...

In this illuminating episode of The Science of Age-less Living , Dr. Ethan Hausman-Marquis takes you on a deep dive into the very foundation of life itself: the central dogma of molecular biology.

Using vivid analogies, Dr. Hausman-...

In this profound episode of The Science of Age-Less Living , host Dr. Ethan Hausman-Marquis explores the atomic fate of the human body after death—specifically through cremation—as a lens to reframe longevity, aging, and what it truly means to preserve life. Drawing on Carl Sagan’s iconic line that “we are made of star stuff,” the episode traces the cosmic origins of the body’s atoms (carbon from...

In this episode of The Science of Age-less Living , Dr. Ethan cuts through the noise around “anti-aging” and peptide culture to lay out what longevity medicine actually is: evidence-based risk management, not influencer-driven optimization. You’ll hear why the biggest threats to lifespan and healthspan are still cardiovascular disease, metabolic dysfunction, neurodegeneration, and cancer—and why n...

In this episode of The Science of Age-less Living , Dr. Ethan argues that aging is not primarily about accumulated damage (oxidative stress, inflammation, telomere shortening), but a loss of timing and synchronization in the body’s biological clocks. The master clock (SCN in the brain) and peripheral clocks in organs coordinate hormones, gene expression, metabolism, repair, and immunity in precise...

In this episode of The Science of Ageless Living , Dr. Ethan Hausman-Marquis unpacks autoimmune fatigue in conditions like MS, lupus, and rheumatoid arthritis—and why it’s so often misunderstood. Fatigue isn’t laziness or deconditioning; it’s a biological safety response to chronic inflammation. He explains how inflammation disrupts neurotransmitters, autonomic balance, and oxidative stress, with...

Why do we age? Is it simply the passage of time — or something far more precise, and far more modifiable? In this episode of The Science of Age-less Living , Dr. Ethan Hausman-Marquis takes you deep into the real biology of aging, revealing why growing older is not an inevitable countdown, but a consequence of accumulated cellular damage and declining repair capacity. You’ll learn why aging is bes...
