They also get into coaching, confidence, and the mental side of competing, sharing practical protocols and personal stories most guests won't share on camera. 🏋️♂️ WORK WITH ME Apply for coaching → https://theoptimizationlab.cc/bio 📘 FREE RESOURCES Mitochondrial Enhancement Blueprint → https://theoptimizationlab.cc/bio Pillars of Fat Loss → https://drive.google.com/file/d/13mtEyUY7WDu2ONRfq-bKwWHP_gjMh4Zs/view Elbow Tendinopathy → https://drive.google.com/file/d/1eHboUOYedtomxHy2MMyKWcHmAqa1F6Yk/view 💪 FOLLOW ME Instagram: https://instagram.com/optimalnathan 🧠 TIMESTAMPS 00:00 - Intro: peptides, hormones, and bodybuilding truths 00:29 - Meet David DeMesquita: credentials and background 01:57 - David's non-traditional path into health coaching 03:14 - The Wolverine stack: TB-500 and BPC-157 for tendons 04:41 - Injecting tendons: pain, microdefects, reattachment 06:57 - Different protocols: hamstring vs. wrist injuries 07:46 - Personal stories: torn hamstrings and recovery time 11:26 - Peptides for micro-injury repair and mitochondrial health 13:33 - Myostatin inhibition and MOTS-c: fact vs. hype 14:57 - MOTS-c's real role: performance, not anabolic 15:55 - MOTS-c, insulin sensitivity, and stress response 17:59 - Growth hormone vs. IGF-1: fat loss vs. muscle 20:00 - Retatrutide and metabolic regulation 22:33 - Growth hormone: fat loss, muscle, and aging 23:38 - Thyroid under steroids: TBG, T4, and T3 28:04 - Managing thyroid health: balancing and supplements 31:53 - Enhanced vs. natural: physiological differences 32:50 - How exogenous hormones alter stress and emotion 34:01 - Long-term cycles: labs, organs, and psychology 35:25 - Emotional regulation and mental health on high-dose steroids 36:24 - Steroids and emotional highs and lows 37:10 - Personal stories: emotional stability on androgens 38:35 - How androgens affect emotional perception 39:04 - Muscle-building, emotional regulation, and burnout 40:37 - Hormones, reward systems, and addiction tendencies 41:06 - GLP-1 drugs like Retatrutide (Reta) and reward pathways 43:09 - Impulsivity and hunger on GLP-1 therapies 44:32 - Drug approval challenges for experimental compounds 46:10 - Mitochondrial peptides, stress, and cellular health risks 49:12 - SLU-PP-332 and mitochondrial function: why monitoring matters 51:18 - Balancing demand and biological capacity in cycles 52:20 - Excessive dosing risks and realistic expectations 53:17 - Peptides as tools, not magic bullets 54:00 - Receptor desensitization and half-life explained 55:22 - Risks of overusing peptides without proper cycling 56:19 - How cycling affects insulin sensitivity 58:36 - Case studies: insulin drops and baseline health 59:00 - Psychological resilience as a coaching skill 1:00:39 - Mental focus and stage prep beyond the physical 1:02:01 - Belief and confidence in athlete success 1:03:25 - Coaching: managing noise, doubt, and confidence 1:04:09 - Building mental toughness and trusting the process 1:05:03 - The human element: coaching beyond physiology 1:05:57 - Emotional and mental health effects of long-term use 1:08:07 - Presentation, stage presence, and posing 1:08:43 - Final thoughts: coaching, confidence, and honesty
