Show notes

Send us Fan Mail That "miracle" peptide in an unlabeled vial isn't the same science as your GLP-1, and the FDA is meeting this week to decide the fate of seven of them. Registered dietitian and GLP-1 user Ana Reisdorf sits down with Tanna Donalson, PA-C, owner of Redbud Medical in Denver, where she prescribes, manages, and monitors peptides for her patients every day. After 15 years in trauma and emergency medicine, Tanna built a practice around exactly this: knowing what each peptide is, what it actually does for a patient, and how to run it safely. Together they break down why semaglutide (Ozempic) and tirzepatide (Zepbound, Mounjaro) belong in a category all their own, the seven peptides on the FDA's table, and the two questions that reveal whether a peptide provider is legit. IN THIS EPISODE - What a peptide actually is, and why your GLP-1 is NOT the same thing as BPC-157 or TB-500 - The seven peptides the FDA is reviewing: BPC-157, KPV, TB-500 (the "Wolverine complex"), MOTS-c, DSIP, Semax, and Epitalon - The "funding gap" — why peptides that can't be patented never get human clinical trials - Six things the FDA worries about in an unlabeled vial, from identity and purity to the cancer/angiogenesis risk - The two questions that tell you if a peptide provider is legitimate (503A/B pharmacies and third-party certificates of analysis) ABOUT THE GUEST Tanna Donalson is a Physician Assistant and Owner of Redbud Medical in Denver Colorado. Her background is in Trauma and Emergency Medicine and she is now specializing in Women's Health and Wellness, Peptides, Weight Loss, Hormones and all things preventative care to help people live longer, healthier lives.
