Peptides: Oral and Injectable

Peptides are everywhere, but how much do we actually know about the oral and injectable versions? Dr. Zain and Courtney continue their peptide conversation by exploring collagen supplements, GHK Copper, BPC 157, ipamorelin, and CJC 1295. They discuss what the current evidence shows, where research is still limited, and why the way a peptide is sourced and delivered matters. The conversation also covers hormone related peptides, potential risks, FDA approval, compounded products, online pharmacies, and the importance of working with a physician instead of self medicating. Dr. Zain and Courtney also break down the difference between established, emerging, and investigational treatments and explain how they evaluate peptides based on their intended goal, supporting evidence, method of administration, and known and unknown risks. They finish by discussing marketing claims surrounding aging and longevity and why improving healthspan may be more meaningful than simply extending lifespan. 00:00 Introduction to oral and injectable peptides 01:00 Collagen peptides and the evidence 03:00 GHK Copper 05:00 BPC 157 and tissue repair 06:00 Ipamorelin and CJC 1295 07:00 Hormones and potential health risks 09:00 FDA approval and experimental peptides 11:00 Understanding the evidence ladder 13:00 Evaluating peptide marketing claims 15:00 Healthspan versus lifespan 16:00 Questions clinicians should ask about peptides 18:00 Where peptides could fit into future healthcare 20:00 Balancing innovation with patient safety 22:00 Taking a closer look before using peptides
