Iron Radio: Popular Peptides in Strength Sports (Sermorelin, TB-500, PEG-MGF) + Show Updates

On Iron Radio, hosts Dr. Lonnie Lowery and Dr. Mike T. Nelson (with Coach Phil Stevens joining later) discuss what an AI scan identified as popular peptides in strength sports, focusing on sermorelin, TB-500, and PEG-MGF. They review purported mechanisms and typical injection use, emphasize limited human data and anti-doping restrictions, and share anecdotes about mixed results—especially for sermorelin and tissue-healing peptides often paired with BPC-157—while raising questions about GH/IGF-1 testing, pituitary responsiveness with age, and product quality from research chemical sources versus compounding pharmacies.

They also touch on movement and brain health, mention Dr. Tommy Wood’s book, note Iron Radio’s updated distribution/feed changes and Mike’s newsletter, and preview Phil’s upcoming meet as he manages knee pain while preparing his 10-year-old son to attempt national-record lifts.

Iron Radio: Top 3 Reasons to Compete in Strength & Physique Sports

Hosts Coach Phil Stevens and Dr. Lonnie Lowery discuss their top three reasons to compete in strength and physique sports: competition provides direction and purpose that sharpens training and nutrition through a clear timeline and accountability; it forces honesty and adherence to strict standards under rules, exposing true performance and differentiating meet PRs from gym PRs; and it ends “someday” thinking by offering a tangible “receipt” of achievement via judged results and public performance. Lonnie adds that competing is also a courage test—overcoming fear and being evaluated in public—while both note the importance of using competition anxiety productively and focusing on personal progress. They also emphasize the value of team support and leading by example, especially when coaching and training with others, and encourage listeners to try competing rather than waiting for perfect conditions.

Iron Radio: AI’s Impact on Coaching & Peer Review, Urolithin A in Sports Nutrition, and Cold Water Immersion Updates

On Iron Radio, hosts Dr. Lonnie Lowery and Dr. Mike T. Nelson discuss how AI may speed content distribution, assist with business tasks, and potentially replace some lower-level coaches while still lacking context for peer review and research interpretation, raising concerns about regulation, healthcare profit motives, and data-center resource demands. They revisit urolithin A (a gut microbiota–derived metabolite linked to mitochondrial effects), referencing a 2025 Frontiers in Nutrition paper and Mike’s personal and client experiences, noting modest perceived recovery/HRV benefits, high cost, and possible responder differences due to gut conversion. Mike also summarizes a broad review on cold exposure and metabolism across organ systems, highlighting mixed recovery data, evidence that immediate post-hypertrophy cold-water immersion can reduce muscle protein synthesis via reduced blood flow, lack of clear anti-inflammatory marker changes, and practical guidance based on season, logistics, and athlete preference.
