4.8K views · 2w ago · 17:05

Are we thinking about GLP-1 medications completely wrong? While widely used for weight loss, a September 2026 Nature study showed that semaglutide extended median lifespan in older mice by 12%, while human trial data revealed favorable improvements across multiple epigenetic aging clocks. In this episode, Dr. Richard Visser examines whether GLP-1 receptor activation directly slows aging or simply reverses metabolic stress. Dr.

989 views · 3w ago · 20:16

When taking GLP-1 medications like Wegovy, Zepbound, or Ozempic, rapid weight loss is celebrated, but losing 20 kilograms does not mean you lost 20 kilograms of fat. Without a muscle-preserving strategy, up to 39% of total weight loss can come from lean tissue, sacrificing the metabolic muscle needed for longevity. In this episode, Dr.

Topics: Why losing 20kg on a GLP-1 is not always a victory · The 2026 meta-analysis: Quantifying lean mass loss on GLP-1s · Why muscle is metabolic tissue and your biological insurance · The danger of severe appetite suppression and protein starvation · Rule 1: Protein-first nutrition (1.6 to 2.0g/kg) · Rule 2: Progressive resistance training (Why walking isn't enough)

Rapamycin: The Longevity Drug Your Doctor Wont Prescibe You

608 views · 1mo ago · 19:01

But what actually changed following the May 2026 evidence review? In this episode, Dr. Richard Visser breaks down the biology of glutathione synthesis, examines the real data from small human trials and larger dose-response studies, and separates mouse model hype from human reality.

Topics: GlyNAC is everywhere: Sorting hype from reality · What is GlyNAC? Providing raw materials for glutathione · Why aging and oxidative stress travel together · Human trial data: Mitochondrial function, strength, and gait speed · The discontinuation study: What happens when you stop taking GlyNAC · The 114-person dose trial: Why baseline deficiency matters

Which one does your body actually need?! HGH VS Peptides

2.6K views · 1mo ago · 33:58

When exploring longevity, muscle preservation, and body composition over 40, the conversation invariably turns to growth hormone and peptides. But the internet is split: one side warns against human growth hormone in favor of natural peptides, while the other dismisses peptides as weak. In this episode, Dr. Richard Visser cuts through the false dichotomies to provide a comprehensive decision framework.

Topics: The HGH vs. peptides debate: Why both sides are too simplistic · Core physiology: How the hypothalamus, pituitary, and liver produce IGF-1 · Age-related decline vs. true adult growth hormone deficiency (GHD) · Compound breakdown: Sermorelin, Tesamorelin, Ipamorelin, and CJC-1295 · The data on CJC-1295 with DAC: Understanding basal elevation and pulses · The IGF-1 diagnostic trap: Why a single blood test isn't enough

3.1K views · 2mo ago · 22:21

Guest: Follistatin Gene Therapy

What if you could turn off the genetic brakes that limit muscle growth? Researchers and biohackers are investigating Follistatin gene therapy—a treatment designed to suppress Myostatin, the protein that controls muscle size. While animal models display extraordinary "double muscling" phenotypes and early human trials offer hope for severe muscular diseases, unregulated gene therapy poses unique risks.

Topics: The double muscling phenotype: How Myostatin works · The reversibility problem with gene therapy · Why muscle is a vital metabolic organ, not cosmetic tissue · Myostatin: The evolutionary brake system · Follistatin isoforms: FS288, FS315, and FS344 explained · Traditional drugs vs. AAV viral gene vectors
