Evidence Assessment for the Degradation Claim The scientific claim that mixing these peptides causes degradation due to pH incompatibility fails to meet evidentiary standards for several reasons: Structural incompatibility with the mechanism: The postulated copper-catalyzed oxidation pathway requires methionine or cysteine residues in the target peptides

In Canada, synthetic injectable peptides are generally regulated as prescription drugs under the Food and Drugs Act, and Health Canada has issued public advisories (April 2026 and earlier) cautioning that unauthorized injectable peptide products are illegal regardless of whether they are labelled 'for research use only.' Research-grade AOD-9604 supplied by Koipeptides is intended for in vitro laboratory study only and is not authorized for any human or veterinary application
Unlike many performance or recovery compounds that are completely foreign to the body, BPC-157 is modeled after a naturally occurring fragment of gastric juice, which is partly why it has drawn so much attention in both research and athletic communities
Without this protein, your stomach simply cannot absorb B12, no matter how much you take orally
