Unlike receptor-defined peptide systems such as GLP-1 receptor agonists, amylin analogs, or growth-hormone / GHRH-related receptor-targeted peptides, BPC-157s reported effects have been attributed in published research to modulation of several intersecting signaling pathways without a definitively established primary molecular target

While formal pharmacokinetic parameters (Cmax, AUC, t1/2) have not been published in peer-reviewed literature for oral dosing in humans, its low molecular weight (173 Da), positive charge, and water solubility support intestinal absorption
