Ben Greenfield Injects This on Every Flight. Here Is His Complete Travel Protocol.

KPV for Travel-Related Gut Issues00:00

Ben Greenfield experiences significant digestive disruption when traveling, often developing loose stools from minor dietary deviations that do not occur at home. He now travels with KPV peptide and injects it every morning, which eliminates nearly all gut issues during travel. The guest confirmed loving KPV as well, noting it was recommended by Gabriel Lyon and produces a noticeable physiological calming effect. Greenfield stated he continues only interventions he can clearly feel working.

Larazotide, Oral BPC-157, and Peptide Safety Considerations00:30

Larazotide was mentioned as an option, though it is primarily for general gut inflammation rather than leaky gut or barrier repair. Oral BPC-157 was suggested as another approach for gut inflammation. Greenfield acknowledged the lack of long-term human clinical research on peptides but emphasized they are short chains of amino acids that act with precision on targeted systems. He noted that reported side effects typically stem from low-quality Chinese imports purchased from non-CGMP "bargain bin" websites rather than the peptides themselves.

Peptide Industry Regulatory Changes01:31

The industry is undergoing significant regulatory pressure, with cease-and-desist letters being issued to many fly-by-night peptide websites. One site the guest previously used has shut down. Peptide Sciences was identified as one of the larger operations that has closed. Greenfield predicts that familiar peptides such as the GLPs and SS-31 (a mitochondrial brain-support peptide) will transition into pharmaceutical channels, while others will become available through 503A compounding pharmacies operating under good manufacturing practices. The era of directly purchasing peptides online via influencer discount codes is likely ending.
