In this episode of the Longevity & Lifestyle Podcast, Claudia von Boeselager sits down with Dr. Alexander Grinberg, one of the few physicians who has worked with peptide therapeutics since the 1980s.Long before peptides became a social media trend, Dr. Grinberg was involved in clinical research using peptide bioregulators in patients with autoimmune disease, immune dysfunction, radiation exposure, viral illnesses, and regenerative medicine. Drawing on more than 35 years of clinical and scientific experience, he explains what peptides can realistically do, where the evidence is strongest, and why personalized medicine matters far more than following influencer protocols.They discuss the biggest mistakes people make when self-experimenting with peptides, why proper diagnostics are essential before starting treatment, cancer considerations, mitochondrial health, immune function, bioregulators, GLP-1 medications, and what the future of peptide medicine may look like.Whether you're curious about BPC-157, GHK-Cu, Epitalon, MOTS-c, SS-31, or simply want to separate scientific evidence from marketing hype, this conversation offers one of the most balanced and informative discussions on peptides available today.In this episode you'll learn:Why peptides are far more powerful than most people realizeThe biggest risks of self-prescribing peptide protocolsWho should avoid certain peptides altogetherThe blood tests and biomarkers to check before startingWhy longevity treatments should always be personalizedThe fascinating history of peptide medicine dating back to the 1980sHow peptides may support healthy aging, immune health and regenerative medicineThe future of peptide therapeutics and precision longevity medicineTimestamps00:00 Introduction01:18 Why peptides need to be treated like real medicines03:30 Blood tests and biomarkers before using peptides05:45 Cancer risks, contraindications and safety07:25 How Dr. Grinberg became one of the first peptide physicians12:10 The history of peptide research in the Soviet Union13:15 Personalized peptide medicine explained19:20 The dangers of self-experimenting with peptides20:00 Growth hormone peptides and cancer concerns22:00 How physicians evaluate peptide protocols25:00 Bioregulators vs modern peptides30:00 Autoimmune disease and peptide therapies36:00 Mitochondrial peptides and healthy aging42:00 GLP-1 peptides beyond weight loss48:00 The future of peptide medicine55:00 Final thoughtsIf you enjoyed this episode, please subscribe, leave a review, and share it with someone interested in longevity, regenerative medicine, and evidence-based health optimization.Connect with Claudia von BoeselagerWebsite: https://llinsider.comNewsletter: https://llinsider.com/newsletterFollow the Longevity & Lifestyle Podcast for weekly conversations with the world's leading experts in longevity, health optimization, and performance.#Longevity #Peptides #Biohacking #HealthyAging #PrecisionMedicine

My guest today is Roger Love - one of the world’s most renowned voice coaches. He has worked with top performers, executives, actors, and public figures, and his work sits at the intersection of voice, confidence, emotional expression, breath, nervous system regulation, communication, and identity. In this conversation, we explore how the way you sound shapes the way people perceive you and the way you perceive yourself.We get into Roger’s framework for mastering the five core voice variables — pitch, pace, tone, melody, and volume — and why most people unknowingly sound monotone, anxious, apologetic, or less confident than they really are. He explains how voice patterns influence emotion, why public speaking fear is really fear of judgment, and how changing the sounds of confidence can actually help build confidence in real life.We also discuss the connection between voice and longevity, Roger’s work using singing and airflow to help people with stuttering and post-stroke speech challenges, and why he believes your voice may be one of the most overlooked tools for improving relationships, self-expression, business, and quality of life.This episode is for anyone who wants to communicate with more clarity, warmth, authority, and authenticity.Timestamps00:00 Why your voice may be shaping your entire life 00:59 Intro to Roger Love and why voice matters beyond performance 02:54 Roger’s origin story — singing, happiness, and becoming a voice coach at 16 08:02 The 5 core voice variables: pitch, pace, tone, melody, and volume 09:50 How emotion shapes the way you should speak — fast vs. slow, loud vs. soft 11:18 Why people remember how you make them feel more than the words you say 16:00 Why monotone voices lose people — and how melody creates engagement 19:23 The “leading tone” technique to keep people listening and prevent interruptions 20:02 How vocal musicality creates emotion, attention, and connection 21:20 Voice, relationships, and longevity — Roger’s perspective on why communication keeps us young 23:14 Roger’s documentary Find Your Voice and the story of helping a lifelong stutterer 25:23 “Solid airflow” and Roger’s approach to stuttering and speech transformation 26:12 Singing, stroke recovery, and helping his mother speak again 27:32 Why public speaking fear is really fear of being judged 28:52 “The sound creates the reality” — how confident speech builds real confidence 46:32 Why voice is a learnable skill, not a fixed trait 47:34 Why nobody is stuck with the voice they have 49:37 The voice makeover idea that could change your life#RogerLove #CommunicationSkills #PublicSpeaking #Confidence

Dr. Darshan Shah is a board-certified surgeon, longevity physician, entrepreneur, and founder of Next Health. After performing more than 20,000 surgeries and training at the Mayo Clinic, Darshan realized something most people never hear from the medical system: treating disease is not the same as creating health. In this episode, he shares the personal health crisis that changed his life, the longevity pyramid he uses with patients, the key biomarkers and scans to know before disease appears, why muscle and metabolic health matter so much, how toxins and hormone disruption are affecting people earlier than ever, and what hyper-preventive medicine may look like in the years ahead.Timestamps 00:00 Intro 01:21 Darshan’s personal health crisis despite medical success 05:51 Why modern medicine treats disease but misses true health 09:51 The longevity pyramid and the few habits that move the needle most 13:27 Why tracking glucose can change how you eat 14:11 Why sitting all day harms metabolic health 17:29 Why muscle and grip strength predict longevity 19:46 DEXA scans, body composition, and key longevity baselines 22:14 The blood markers to know before disease shows up 26:51 Functional medicine testing - gut health, hormones, and stress 30:54 Microplastics, toxins, and why hormones are getting disrupted earlier 35:24 How to detox your home without getting overwhelmed 36:48 Hyper-preventive medicine for heart disease, cancer, brain health, and lung health 43:15 Peptides, stem cells, and when advanced therapies actually make sense 44:04 Why chronic disease may not need to be your destiny 45:24 What’s next for Darshan and Next Health #Longevity #HealthOptimization #MetabolicHealth #PreventiveMedicine #Biohacking

Dr. Bilal Chughtai is a board-certified urologist and expert in women’s urinary health, recurrent urinary tract infections, the urinary microbiome, and preventative urology.In this episode, Claudia speaks with Dr. Chughtai about why bladder health deserves far more attention in the longevity conversation - especially for women dealing with recurrent UTIs, menopause, changing hormones, and the often-overlooked effects urinary health can have on cognition, confidence, intimacy, travel, and quality of life.They explore why UTIs are so common in women, why they often become more frequent with age, how estrogen loss during menopause changes the bladder environment, and why repeated antibiotic use may not always be the best long-term solution.
