In rats given BPC-157, serotonin levels in the brain increase in specific regions while simultaneously decreasing in other regions, such as the hippocampus.[ref] A 2020 study found that BPC-157 reduced leaky gut syndrome by stabilizing gut permeability after NSAID use.[ref] Reducing leaky gut theoretically can affect the gut-brain axis and reduce inflammation

Appetite Regulation and Eating Behavior Research Satiety and Food Intake Studies Research on individual components revealed distinct but complementary appetite effects[17]: Cagrilintide reduced food intake through amylin-mediated satiety pathways in rodent models GLP3 decreased meal size and frequency through multiple receptor mechanisms Combined approaches showed additive effects on appetite suppression Food noise reduction reported anecdotally in human studies (reduced food preoccupation) Critical Research Limitation: While individual components (GLP3 and cagrilintide) have extensive phase 2 and phase 3 clinical trial data, research specifically examining the combined GLP3 + Cagrilintide formulation as a blend is extremely limited
