Retatrutide Masterclass: How To Use It Optimally (Dose, Frequency, Diet, Exercise, & Supplements)

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?
