The copper is chelated to the peptide and used locally by skin cells
Impurity Markers to Check Common synthesis-related impurities in tripeptide products include truncated sequences (Gly-His or His-Lys fragments), residual coupling reagents, and counterion residues from purification
Structural and tissue-repair peptides like BPC-157, TB-500 (Thymosin Beta-4), and collagen peptides carry the lowest documented interaction risk because they operate through angiogenesis, wound healing, and anti-inflammatory pathways with negligible CNS penetration
