The Precision Peptide Genetic Test reveals predispositions across GLP-1R, GIPR, and related metabolic genes (FTO, MC4R variants)

Published in Pharmaceuticals (PMID: 38675421), this 41-page open-access review proposes that BPC-157, while not meeting classical neurotransmitter criteria, functions as a cytoprotection mediator with neurotransmitter-like activity through a network of interconnected evidence. What Makes BPC-157 Unique BPC-157 is a 15-amino acid peptide (sequence: GEPPPGKPADDAGLV, molecular weight 1419) native and stable in human gastric juice for over 24 hours, showing no sequence homology with known gut peptides
