• Do Peptides Cause Cancer? BPC-157, TB-500, CJC-1295 & More
    Sep 5 2026
    "Do peptides cause cancer?" is one of the most common questions about BPC-157, TB-500, and the GH peptides—and it's also the most misunderstood. You're normally given one of two answers: yes, be terrified, or no, don't worry about it. Neither is right, because this was never a yes-or-no question. Cancer doesn't work that way—and once you understand how it actually does work, the question reshapes into something far more useful for deciding how to use these compounds. In this video, Dr. Quinn Stillson (MD + strength coach) breaks down the complete framework: the three stages of cancer development, exactly which peptides act at each stage and how, actual estimated risk numbers for every peptide on the list, and what you should do differently because of it. Every peptide is placed against real-world comparators—obesity, alcohol, sedentary time, acromegaly, EPO, and organ transplant immunosuppression—so you know what "increased cancer risk" actually means in practice. In this video, you'll learn: What it actually means for something to "cause" cancer—initiation, promotion, and progression Why ~60% of men over 79 already have prostate cancer—and why that isn't as scary as it sounds Why no peptide can INITIATE cancer (and the one contaminant that can) Which peptides may actually LOWER your cancer risk (GLP-1s, Thymosin Alpha-1, MOTS-c, Epitalon, GHK-Cu) Melanotan I vs II: the human data, the case reports, and the UV confounder nobody mentions GH peptides: why the feedback system matters, and why IGF-1 LR3 and PEG-MGF are different Follistatin's two-faced relationship with cancer—promoter or suppressor? BPC-157: does it promote angiogenesis or just modulate it? Evaluating the anti-tumor claim TB-4/TB-500: the most concerning peptide on the list, and exactly why Arsenic in research-use-only vials—the Belgian study that found 10x the injectable limit Why "if peptides caused cancer, wouldn't we know by now?" is wrong—the Xeljanz lesson Estimated risk ranges for EVERY peptide, compared to obesity, alcohol, and smoking The four things that actually reduce your risk: screening, sourcing, dosing, and cycling Best for: – Anyone using BPC-157, TB-500, CJC-1295, Ipamorelin, IGF-1 LR3, or Melanotan – People who've heard peptides cause cancer and want the actual evidence – Anyone with a personal or family history of cancer considering peptides – Biohackers and clinicians who want mechanisms and numbers, not fear or dismissal – Anyone deciding whether the risk-benefit of a specific peptide is worth it Timestamps 00:00 Do Peptides Cause Cancer?

  • Retatrutide Masterclass: How To Use It Optimally (Dose, Frequency, Diet, Exercise, & Supplements)
    Jun 26 2026
    Retatrutide is the most powerful weight loss peptide ever studied—but the drug is only half the equation. HOW you use it determines whether you walk away lean, strong, and metabolically healthier, or whether you lose muscle, watch your skin and hair suffer, tank your energy, and STILL leave fat loss on the table. The same appetite suppression that makes Retatrutide so effective is exactly what gets people into trouble when they lose weight too fast. In this video, Dr. Quinn Stillson (MD + strength coach) breaks down the complete practical framework for using Retatrutide optimally—the monitoring, training, diet, supplementation, and the full dosing, frequency, timing, and cycling strategy. Every recommendation is built from the clinical evidence and tied back to the single most important variable: finding YOUR optimal rate of weight loss. This is Part 2—the "how to" guide. If you haven't decided whether Retatrutide is right for you yet, watch Part 1 first. In this video, you'll learn: Why your speed of weight loss is the master variable—and how it drives muscle, bone, skin, hair, and metabolic outcomes The complete lab panel to run on Reta, how often, and how to interpret it Vitals monitoring: resting heart rate, HRV, and blood pressure—and when they signal it's time to stop How much lean mass loss is too much (and why "lean mass" isn't what you think) The optimal exercise routine: resistance training specifics + fasted zone 2 cardio logic Tier 1–3 diet framework: calorie deficit, protein targets, hydration, timing, and quality How to avoid GI side effects (nausea, constipation, and the nausea spiral) The top supplements on Reta—plus collagen, calcium, and EAAs Why oral/sublingual Reta is a scam and it must be subq The four dosing principles and your best STARTING dose for YOUR situation Dose escalation: how and when to move up (and why the standard max dose is too high) Should you split your dose across the week? What the data actually shows Best time of day to inject—optimizing for tolerability over efficacy How long to stay on, whether to cycle, weaning, and switching to other GLP-1s Best for: – Anyone currently on or starting Retatrutide who wants to use it optimally – People worried about losing muscle, hair, or skin quality on a GLP-1 – Lifters and athletes wanting to protect lean mass during weight loss – Biohackers and clinicians wanting an evidence-based protocol, not a one-size-fits-all cycle – Anyone who watched Part 1 and is ready for the practical guide Timestamps 00:00 Why Using Retatrutide Incorrectly is Ineffective and Dangerous 01:50 Optimal Rate of Weight Loss - The Dangers of Losing Weight Too Fast 06:55 Lab Monitoring - Lab Panel, Frequency, and How to Interpret 12:59 Vitals Monitoring - Heart Rate, HRV, Blood Pressure 15:32 Body Composition Monitoring - How Much Lean Mass Loss is Too Much? 23:25 Optimal Exercise Routine - Specifics for Strength Training and Cardio on Reta 28:30 Diet - Best Calorie Deficit, Amount of Protein, and Water 34:20 Diet - Protein Timing + Quality & Carbs with Reta 39:24 How to Avoid Side Effects (Nausea, Constipation, etc) 41:07 Best Supplements on Reta - Top 5 + Collagen, Calcium, EAA’s 46:12 Form of Administration - Can You Take Retatrutide Orally? 46:58 Dosing Principles - Variable Responses and Balancing Efficacy, Cost, & Side Effects 48:38 Best Starting Dose Depending on YOUR Situation 53:31 Dose Escalation - How and When to Increase Your Dose 59:38 Max Dose for Retatrutide - Why the Standard Max Dose is Too High 01:00:57 Optimal Frequency - Should You Split Up Your Reta Dose Throughout the Week? 01:05:24 Best Time of Day to Inject Reta - Optimizing for Side Effects and Efficacy 01:07:19 How Long to Stay on Reta - Should You Cycle?

  • Full Body MRI: Who Should (& Should Not) Get One
    Oct 17 2026
    Should you get a full body MRI? Most people decide based on cost. That's the wrong question. Even with unlimited money, for the average person the scan sends roughly 10 people down a path of potential harm for every 1 it potentially helps. But there is a specific group of people where it's worth it, and this video shows you how to find out if you're one of them. In this video, Dr. Quinn Stillson (MD, A4M board-certified in longevity medicine) walks through the actual evidence on whole body MRI screening, the kind sold direct-to-consumer by Prenuvo, Ezra (now Function Health) and others: what a standard scan can and can't see, how likely it is to find something that matters for YOU, the real numbers on incidental findings, biopsies and overdiagnosis, and a step-by-step framework for deciding. No sales pitch, no "it's a scam." Just the data, finding by finding. The result: a three-tier system for who should get one, who shouldn't, and how to do it right if you do. In this video, you'll learn: Why a full body MRI is NOT the same as an MRI of every body part (and what that costs you in detail) The cancers it actually sees well vs. the ones it's nearly blind to (colon, breast, lung, prostate) Which sequences a scan needs (T1, T2, STIR, DWI, Dixon) and the tell for a scan that's skipping them The add-ons: brain MRA, FLAIR, volumetrics, cardiac strain, body composition. Which are worth it The real cancer detection rate (1.57%) and how your genes, family history and medical history change it The non-cancer findings that can change what you do: fatty liver, AAA, spine fractures, pancreatic cysts, brain aneurysms, meningiomas Tracking data (brain volume, muscle quality, organ volumes): what the scan adds over DEXA and bloodwork Why ~30% of people get an indeterminate finding and only 2-4% have something serious The hidden costs: anxiety, extra imaging, radiation, biopsies, surgery for benign findings Overdiagnosis: why 42-58% of screen-detected kidney cancers were never going to hurt anyone The decision framework: elevated AND spread-out risk, the tracking gate, age, and anxiety The three tiers (and the "do not get one" list) How to do it right: the 3 questions to ask the provider, ONCO-RADS, and planning repeat scans Best for: – Anyone considering a Prenuvo, Ezra or other direct-to-consumer full body MRI – People with a family history or genetic risk trying to figure out if the scan actually helps them – Longevity enthusiasts who want the tracking data and need to know if it's worth it – Anyone who already got one and is staring at an "indeterminate finding" – Clinicians who want the numbers, not the marketing Timestamps 00:00 Should You Get a Full Body MRI? Why This Is Not a Cost Question 01:51 Full Body vs Dedicated MRI - Why It Sees Less 03:54 Cancers It Detects & Misses 05:38 Other Findings It Detects & Misses (Aneurysms, Cysts, Fractures, Etc) 07:10 Not All Scans Are Equal: Sequences & Skimping 09:11 Add-Ons - Body Comp, Brain MRA & Volumetrics, Heart Strain, Organ Aging 11:12 Cancer Detection Rate in YOU & Why It's Individualized 12:50 Genes, Family History, & Medical History: What Raises YOUR Odds 15:42 Fatty Liver, AAA & Spine Fractures 18:19 Pancreatic Cysts, Heart Strain & Brain Aneurysms 21:30 Tracking: Muscle Quality, Brain Volume, & Organ Aging 23:28 Risk #1 - The 30% Problem (Indeterminate Findings) 24:54 Anxiety, Extra Imaging, Biopsies & Surgery 28:31 Overdiagnosis - Was the Cancer ACTUALLY Going to Hurt You? 31:26 Should YOU Get One?

  • Retatrutide vs Semaglutide & Tirzepatide: Should YOU Actually Take It?
    Jun 5 2026
    Retatrutide is the most powerful weight loss peptide ever studied—a triple agonist hitting GLP-1, GIP, AND glucagon receptors, producing up to 28.7% body weight loss in Phase 3 data. But being the BEST at weight loss doesn't automatically make Retatrutide the best peptide for YOU. The answer depends on your starting weight, your metabolic health, your cardiovascular risk, and whether you're chasing fat loss or longevity. In this video, Dr. Quinn Stillson (MD + strength coach) breaks down the complete science behind Retatrutide and compares it head-to-head against Semaglutide (Ozempic/Wegovy) and Tirzepatide (Mounjaro/Zepbound)—separating what the data actually shows from what the peptide community assumes. We cover the structure, the triple-receptor mechanism, the real clinical data, the emerging side effect signals, and the longevity question most channels completely skip. By the end, you'll have a clear risk-benefit framework for deciding whether Retatrutide is right for your specific situation. In this video, you'll learn: What Retatrutide is and why the GIP backbone makes it structurally unique How biased agonism changes the GLP-1 potency story What GLP-1, GIP, and glucagon receptor activation each actually do The truth about the "increased energy expenditure" claim Real weight loss data vs Semaglutide and Tirzepatide The muscle/lean mass loss concern—and what the data shows Metabolic effects: liver fat, triglycerides, LDL, HDL, blood pressure, heart rate Why the level of evidence matters more than people think New side effects: dysesthesia, arrhythmias, discontinuation rates Should YOU take it if obese or diabetic? Should YOU take it if NOT obese or diabetic? Retatrutide and longevity: the GIP/Sirt1 and glucagon/AMPK paradoxes Best for: – Anyone considering Retatrutide for weight loss or body composition – People comparing GLP-1, dual, and triple agonists – Longevity-focused individuals weighing peptides for healthspan – Clinicians and biohackers wanting an evidence-based breakdown – Anyone tired of the hype who wants honest risk-benefit analysis Timestamps 00:00 Retatrutide = Best Peptide for Weight Loss, But Is It The Best Peptide For YOU? 01:15 Retatrutide Structure & How it Activates GLP-1, GIP, and Glucagon Receptors 05:31 GLP-1 Receptor Effects - Longevity, Weight, & Glycemic Control 08:12 GIP Receptor Effects - Metabolic Synergy & Questionable Longevity Effects 10:52 Glucagon Receptor Effects - Increased Energy Expenditure But Longevity Harm? 16:29 Retatrutide Weight Loss Effects (vs Semaglutide & Tirzepatide) 18:51 Muscle Loss Concern with Retatrutide (vs Semaglutide & Tirzepatide) 21:03 Retatrutide Metabolic Effects (Cholesterol, Liver Fat, Glycemic Control, Blood Pressure, HR) 25:30 Lower Level of Evidence for Retatrutide (vs Semaglutide & Tirzepatide) 28:17 Retatrutide Side Effects: Dysesthesia, Arrhythmias, More Severe GI Effects 30:05 Should YOU Take Retatrutide (If You’re Obese or Diabetic)? 33:20 Should YOU Take Retatrutide (If You’re NOT Obese or Diabetic)? 36:25 Retatrutide for Anti-Aging & Lifespan Extension (vs Semaglutide & Tirzepatide) 41:02 Is Retatrutide the Best GLP-1 for YOU & Free Peptide Guide Get the free peptide guide at my website: quinnstillsonmd.com Purchase the Hume Body Pod below (FSA/HSA eligible) — up to 50% off!

  • I Ranked Every Way to Build Muscle & Lose Fat - Most Aren't Worth It.
    Sep 19 2026
    Most people building muscle and losing fat are optimizing the wrong variable. The single fastest studied way to gain muscle adds 13 lbs of lean mass in 10 weeks — but effectiveness alone tells you nothing about whether something is worth doing. The interventions with the biggest body composition effects are very often the worst things you can do for your long-term health. In this video, Dr. Quinn Stillson (MD + strength coach) ranks EVERY body recomposition intervention on three axes: how much muscle and fat it actually moves in kilograms, what it costs you on the longevity axis, and how much human evidence actually exists. Everything gets plotted on one graph — from creatine to trenbolone — so you can see the trade-off for yourself instead of being told what to think. The result: five free, unglamorous interventions get you 80–90% of the best body composition you can reach without paying for it somewhere else. Everything else is competing for what's left. In this video, you'll learn: Why testosterone is the perfect case study for how dose and duration drive BOTH efficacy and longevity harm Tier 1: the exact resistance training volume, cardio prescription, step count, deficit size, protein target, and sleep parameters — with the kg effect size for each How much muscle and fat you can actually gain and lose naturally (the FFMI ceiling) Why GLP-1s are Tier 1b and not Tier 1 — and what most people get wrong about muscle loss on them Comprehensive lab optimization: the full panel and what fixing your deficiencies is actually worth Creatine's real effect size — and why it nearly matches TRT at 1% of the cost GH peptides: the honest efficacy number, who's a candidate, and why the gains are rented, not owned Myostatin/activin inhibitors (bimagrumab) — the best recomp data in existence, and why you can't get it MOTS-c, 5-Amino-1MQ, SLU-PP-332 — what the animal data shows and why it likely won't transfer Anabolic steroids: what they actually give you, what the cardiovascular data really says, and how much you keep after stopping Supraphysiologic GH: 27 RCTs, increased lean mass, zero strength improvement SARMs, insulin, clenbuterol, and DNP — ranked honestly, not dismissed Why HMB, collagen, omega-3, citrulline, and EAAs didn't make any tier Best for: – Anyone who wants to build muscle and lose fat without trading away healthspan – People currently using or considering peptides, TRT, or anabolic steroids – Lifters who've plateaued and are deciding what to add next – Clinicians and biohackers who want effect sizes and evidence grades, not opinions – Anyone tired of being sold supplements that do nothing Timestamps 00:00 Efficacy, Longevity, & Strength of Evidence - The Ranking Axes 01:59 Testosterone (Men & Women) - Doses for Efficacy + Longevity 07:41 Importance of Tier 1 & How We’re Ranking the Interventions 09:18 Optimizing Resistance Training for Muscle Growth 12:24 Optimizing Aerobic Training for Body Recomp 16:41 Tracking NEAT (Non-Exercise Activity Thermogenesis) 18:22 Calorie Deficit - How Large Should Your Deficit Be? 20:09 Protein - Daily Amount & Timing 22:45 Sleep Optimization for Body Recomp - Duration, Timing, Alcohol 26:14 How Much Muscle Can You Actually Gain Naturally with Tier 1? 28:29 How to Track Body Composition at Home 30:16 GLP-1s - Why They’re NOT Tier 1 35:00 Cagrilintide & Amylin Agonists - Add-Ons to GLP-1s? 36:24 Myostatin/Activin Inhibitors (Bimagrumab) - The Future of Body Recomp? 38:12 Tier 2 - Lab Optimization (+ Starting Lab Panel for Body Recomp) 42:56 Creatine - Why It’s Still UNDERrated 45:27 Tier 3 - GH Peptides - ACTUAL Effect Size (Overrated?) 51:33 Tier 4 - MOTS-c - Do You Need it to Optimize GLP-1 Use? 54:24 5-Amino-1MQ & SLU-PP-332 - Worth The Cost? 56:59 Tier 5 - Anabolic-Androgenic Steroid Use (Long-Term) 01:01:21 Short-Term Anabolic Use - Lower Risk? 01:05:08 Efficacy of Short-Term Anabolic Use - Do Gains Last After Stopping? 01:09:34 Growth Hormone (Supraphysiologic) & GH vs GH Peptides 01:13:17 SARMs, Insulin, Clenbuterol, & DNP 01:15:40 Why Most Interventions Aren’t Worth It Get the free peptide guide at my website: quinnstillsonmd.com Purchase the Hume Body Pod below (FSA/HSA eligible) — up to 50% off!

  • Selank Deep Dive: Anxiety, Cognition, Immune System - Mechanisms, Risks, Forms, & Dosing
    Feb 20 2026
    Selank is far more than just an anti-anxiety peptide - it's a synthetic heptapeptide derived from Tuftsin (a natural immune molecule in your body) that has been approved in Russia since 2009 and even made over-the-counter in 2017. But what does the science actually show? And how do its mechanisms, risks, and clinical data stack up? In this video, Dr. Quinn Stillson (MD + strength coach) breaks down the full science behind Selank: how it modulates GABA, glutamate, opioid, and monoamine systems to reduce anxiety, why its immunomodulatory Tuftsin-derived properties matter, how it compares to benzodiazepines, and what the Russian clinical studies actually demonstrate - while clearly separating evidence from speculation. Whether you're dealing with anxiety, brain fog, immune dysfunction, gut issues, or building a cognitive performance stack—this is the definitive deep dive on Selank. In this video, you'll learn: What Selank actually is and how it was derived from Tuftsin Why Russia approved it as an OTC drug—and what that means for the evidence base How Selank modulates GABA, glutamate (NMDA), opioids, and monoamines for anxiolytic effects How Selank compares to benzodiazepines in head-to-head human studies Why Selank likely avoids tolerance and dependence unlike benzos Immunomodulatory, anti-inflammatory, and antiviral mechanisms Cognitive performance, memory, and nootropic effects Benefits for depression, adjustment disorder, pain, stroke recovery, and gut health Safety concerns, drug interactions, and theoretical long-term risks Intranasal vs. subcutaneous Selank—when to use each Optimal dosing for nasal spray and injectable forms Frequency and cycling strategies to maximize benefit and minimize risk Who benefits most from Selank—and who should be cautious Best for: – Anyone dealing with anxiety, stress, or mood disorders – Those looking for a benzodiazepine alternative without dependence risk – Individuals seeking nootropic or cognitive performance support – People with autoimmune, inflammatory, or recurrent infection concerns – Those with gut symptoms tied to stress or anxiety – Clinicians exploring peptide-based psychiatric and immune therapies – Biohackers wanting an evidence-based breakdown of Selank Timestamps 00:00 Why Selank Is MUCH More Than an Anti-Anxiety Peptide 00:44 Selank’s Approval and Over-the-Counter Status in Russia 03:00 How Selank Was Derived from an Immune System Molecule (Tuftsin) 05:32 Immunomodulating Effects of Selank - Anti-Viral, Anti-Inflammatory, & More 07:19 Anti-Anxiety Mechanisms of Selank (GABA, Glutamate, Opioids, Serotonin) 11:38 Selank’s Studied Anti-Anxiety Benefits (Animal & Human Studies) 13:14 Selank vs Benzodiazepines - Tolerance, Dependence, and Side Effects 16:09 Cognitive Performance (Nootropic) Effects of Selank (Memory & Learning) 18:04 Other Mental Health Benefits of Selank (Depression & Adjustment Disorder) 19:28 Pain Reduction & Stroke Recovery with Selank 20:50 Gut Health Effects of Selank (Anti-Ulcer & Microbiome Regulation) 22:07 Risks & Safety Concerns of Selank (Tolerance, Dependence, Long Term Impact) 24:14 Possible Drug Interactions or Immune Dysregulation with Selank 26:05 Who Might Benefit from Selank?

  • CJC-1295, Ipamorelin, Tesamorelin & Sermorelin: Deep Dive on the Best GH Peptides
    Apr 5 2026
    Growth hormone peptides like CJC-1295, Ipamorelin, Tesamorelin, and Sermorelin are some of the most popular compounds in longevity and performance medicine—but most people using them are asking the wrong question. They want to know which peptide increases GH the most. But more GH isn't always better, and the way you increase it matters just as much as how high you drive it. In this video, Dr. Quinn Stillson (MD + strength coach) breaks down the full science behind GH peptides: how growth hormone actually works, why CJC-1295 with DAC disrupts normal physiology, what the clinical data on Tesamorelin and Sermorelin actually shows, why Ipamorelin is the only GHRP worth recommending for most people, and how to weigh the real benefits of these peptides against their real risks—including insulin resistance, cancer progression, and potential lifespan tradeoffs.

  • GHK-Cu (Copper Peptide) Deep Dive: Mechanisms, Benefits, Risks, Forms, & Dosing
    Jan 24 2026
    GHK-Cu (Copper Peptide) is one of the most biologically active and versatile peptides ever discovered—playing a critical role in tissue repair, skin regeneration, hair growth, inflammation control, and gene regulation. Naturally present in human plasma, saliva, and urine, GHK-Cu declines with age, and that decline may contribute to slower healing, skin aging, hair loss, and impaired regenerative capacity. But what does the science actually show? And how far do the benefits really extend beyond skincare? In this video, Dr. Quinn Stillson (MD + strength coach) breaks down the full science behind GHK-Cu: how it binds copper, regulates over 4,000 human genes, modulates inflammation, stimulates collagen and extracellular matrix repair, enhances angiogenesis, and supports stem-cell–like regenerative signaling. We explore the human, animal, and mechanistic data on skin aging, hair regrowth, wound healing, musculoskeletal repair, cardiovascular health, gut and lung tissue integrity, neuroprotection, and even cancer-related pathways—while clearly separating evidence from speculation. Whether you're interested in skin rejuvenation, hair restoration, injury recovery, or building a serious longevity stack—this is the definitive deep dive on GHK-Cu. In this video, you’ll learn: What GHK-Cu actually is and why it naturally declines with age How GHK-Cu regulates thousands of genes involved in repair and inflammation Why it’s one of the most powerful peptides for skin regeneration and collagen synthesis The evidence for hair regrowth and follicle stimulation Effects on wound healing, angiogenesis, and connective tissue repair Anti-inflammatory and antioxidant mechanisms Potential benefits for cardiovascular, lung, gut, and nervous system health GHK-Cu and cancer pathways: what’s protective vs theoretical Topical vs injectable GHK-Cu—what the data suggests Dosing ranges, frequency, cycling strategies, and timing Copper toxicity concerns, safety considerations, and lab monitoring Who may benefit most—and who should be cautious Best for: – Anyone focused on skin health, hair regrowth, or anti-aging – Individuals recovering from injuries or chronic inflammation – Longevity-focused individuals optimizing tissue repair and regeneration – Clinicians exploring regenerative and peptide-based therapies – Biohackers wanting an evidence-based breakdown of copper peptides – Those curious about injectable vs topical peptide strategies Timestamps 00:00 GHK-Cu - Most Versatile Peptide? 00:41 Structure and Mechanism of GHK-Cu 02:19 Skin Regeneration & Anti-Aging Effects of GHK-Cu 08:08 Hair Growth Effects of GHK-Cu 09:23 Anti-Inflammatory & Anti-Oxidant Actions of GHK-Cu 12:03 Musculoskeletal, Gut, Lung, & Liver Healing from GHK-Cu 18:27 Anti-Cancer Actions of GHK-Cu 21:21 Cardiovascular Effects of GHK-Cu (Decreasing Fibrinogen) 23:10 Neuroprotection & Neurologic Effects of GHK-Cu 25:41 Longevity & Anti-Aging Effects of GHK-Cu 28:00 Copper Toxicity Risks and Lab Monitoring While on GHK-Cu 31:15 Cancer Risk With GHK-Cu 32:19 Overall Safety Profile and Topical Safety 33:05 Limiting Burning Sensation with Injectable GHK-Cu 33:51 Who Might Benefit from GHK-Cu?
