bpc 157 evidence human studies safety This doesn't mean BPC-157 is side-effect-free. But it does add to the signal. Credit to @dr.kseniamiami for mentioning this study on our recent podcast recording last week which will be out BPC-157: Experimental Peptide Creates Risk

However, and this is the part that is incredibly important, serum B12 alone can be an unreliable marker of deficiency

Several factors contribute to its apparent safety profile: Natural origin: BPC 157 peptide is derived from a protein that already exists in the human body (gastric juice), making it less foreign to our biological systems than synthetic compounds with no natural analogues

FAK-Paxillin Pathway and Cell Motility BPC-157 has been shown to activate the focal adhesion kinase (FAK)-paxillin signalling pathway, which governs cell motility, migration, and adhesion to the extracellular matrix
