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

Dream vividness sometimes increases, suggesting improved REM cycling

Cellular Turnover and Pigmentation One of the less-publicized but clinically notable effects of GHK-Cu is its influence on cellular turnover rate
