The few that do, like certain peptide capsules , rely on protective coatings, permeation enhancers, or the unusual gastric stability of specific peptides like BPC-157
Instead, its research-relevant effects appear to involve modulation of several signalling pathways most prominently angiogenesis via the VEGF pathway, gastric and gut-lining protective signalling, and to a lesser extent growth factor modulation and nitric oxide system interaction
It also exerts a neuroprotective effect by maintaining mitochondrial integrity
