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.
