EP 120 Peptides Demystified: What They Are, What They Do, and Who Should Stay Away

Episode Summary In this episode of Longevity Unlocked, Coach Kyle and Dr. K explore the science behind peptides, explaining what they are, how they work, and why they have become a major topic in longevity and biohacking. They cover key categories including healing, growth hormone, longevity, brain, immune, and metabolic peptides, separating evidence-based science from marketing claims. The discussion highlights BPC-157 and TB-500 for healing, CJC-1295, Ipamorelin, and Tesamorelin for growth hormone support, Epithalon for longevity, and Dihexa and BDNF for cognitive health. The episode also emphasizes the risks of unregulated peptide sourcing and explains why most peptides are not recommended for people under 18, with brain peptides discouraged for anyone under 25. Listeners will walk away with a clearer understanding of: What peptides are and how they differ from amino acid supplements. Why BPC-157 and TB-500 support healing but don't repair structural damage. How growth hormone peptides differ and when medical oversight is needed. Why Epithalon stands out as a longevity peptide. How Dihexa and BDNF support brain function. Why peptide sourcing and age guidelines matter. This episode is the most thorough, practical breakdown of peptides we've done — designed to help you understand what you're actually taking before you take it. Key Takeaways Peptides are amino acid chains that trigger specific biological functions. BPC-157 and TB-500 support healing but do not repair structural injuries. Growth hormone peptides range from Ipamorelin to advanced protocols requiring medical supervision. Epithalon supports longevity, while Dihexa and BDNF support brain health. Thymosin Alpha-1 boosts immunity but may worsen active Lyme disease. IGF-1 LR3 carries serious risks, including low blood sugar and potential cancer concerns. Peptides are not recommended for people under 18, and brain peptides should be avoided under 25. Use only vendors with FDA-approved API sourcing and lot-specific COA testing.
