System Verdict
Impressive peptide cocktail with 1% Copper Tripeptide-1, but efficacy held back by unproven synergistic concentrations and water-based instability of GHK-Cu. Efficacy score of 3.7 reflects strong Tier 1 Copper Tripeptide-1 (clinically studied for collagen stimulation) paired with synergistic peptides like Matrixyl (Palmitoyl Tripeptide-1/7) and Argireline (Acetyl Hexapeptide-8), plus humectants and amino acids for barrier support; deducting 0.8 for unknown exact peptide concentrations (likely sub-0.1% for most except Copper at 1%), potential pH instability (citric acid present but no specified pH), and lack of encapsulation in dropper packaging which risks oxidation of sensitive copper peptides[1][2][3].
