Questions about copper peptide labels
Which copper peptide serum has the highest GHK-Cu percentage?
Of the serums in this registry, koppā's GHK-Cu Serum states the highest GHK-Cu percentage: 2% in a 45 ml bottle. NIOD states 1% GHK-Cu, The Ordinary 1% copper peptides, COSRX 0.5% and Peach & Lily 0.2%. Among creams, Neurogan states 4% in its Advanced Face Repair Cream.
Which copper peptide serum is the best value?
Use the listed bottle price, pack size and stated concentration as separate comparison points. A percentage does not predict results, and brands may use different concentration bases.
What does "copper peptides 1%" mean on a label?
It depends on the wording. "2% GHK-Cu" is the peptide by weight of the formula. "Copper peptides 1%" can cover more than one copper ingredient, and a "complex" percentage is the weight of a blend, so it says less about GHK-Cu itself. Look for Copper Tripeptide-1 in the ingredient list.
Why do so many products not state a percentage?
Brands are required to list ingredients, not amounts. Nine of the 23 products here list a copper peptide without saying how much. koppā states its GHK-Cu percentage on every label: 2% in the serum, 0.5% in the capsule cream and the balm stick.
How often is the registry checked?
Each row shows the date its brand page was checked. We re-check rows before every update and correct anything we get wrong; send corrections to hello@koppabeauty.com. The full table can be downloaded as a CSV file from the link above it.
