Aug 27, 2026 · 27m

Summary

This episode of Sliced Bread investigates the trend of unregulated experimental peptides, such as the "Wolverine Stack," marketed for healing and anti-aging. Host Greg Foot and longevity expert Dr. Andrew Steele examine the scant scientific evidence, noting that most data comes from animal studies or tiny, flawed human trials. The discussion highlights significant risks, including contamination, incorrect dosing, and potential cancer acceleration, concluding that current claims are largely marketing hype rather than proven medical benefits.
