Episode notes
BPC-157 Is Powerful but Not A Panacea
- BPC-157 is an endogenous gastric peptide with broad healing and neuroprotective effects, but dosing and product quality matter.
- Yurth warns BPC alone won't replace foundations like hormones and micronutrients for recovery.
Ask About Pharmacy Oversight And COAs
- Ask your practitioner whether peptides come from a compounding pharmacy with regulatory oversight and sterility testing.
- Elizabeth Yurth cautions that COAs from research vendors follow lower standards and can hide contaminants.
Radfest Injection Incident
- Yurth recounts an incident at Radfest where a doctor injected attendees and about 30 people had adverse reactions, with two hospitalized.
- She uses the example to illustrate risks of unsupervised peptide injections at events.
