Plausible degradation pathways include: Serum aminopeptidases (cleaving from the N-terminus) Endopeptidases (internal bond cleavage) Hepatic uptake and degradation Renal clearance (though direct renal excretion of intact peptide of this size is typically limited) Whether BPC-157 generates active metabolites i.e., smaller peptide fragments that retain biological activity is not established in the public literature
