Peptide research brief BPC-157: mechanism, in vitro studies, and gaps in human evidence Common name BPC-157 Classification Synthetic peptide fragment (gastric pentadecapeptide) Sequence GEPPPGKPADDAGLV Molecular formula C62H98N16O22 Molecular weight 1419.55 Da CAS 137525-51-0 BPC-157: mechanism, in vitro studies, and gaps in human evidence The proposed bpc-157 mechanism of action centers on a pro-angiogenic signaling cascade reported across rodent and cell-culture experiments, with VEGFR2 receptor activation and downstream endothelial nitric oxide synthase (eNOS) phosphorylation as the most frequently cited nodes (Hsieh et al., 2017
