Your Previous Serums Weren't Broken. The Dose Was.
If you've tried copper peptides before and got nothing, it's almost certainly because they were dosed at 0.25–0.5% — a fraction of what the research studied. The ingredient works. Most brands just don't use enough of it. At a full 2%, this is the concentration that actually signals collagen production. Two to three drops, 60 seconds to absorb, done.

Why the dose is the whole story
GHK-Cu has been studied topically since 1973. The research documenting real collagen signaling uses 1–2% concentration. Most brands sell 0.25–0.5% — enough to print on the label, not enough to do anything. Division Twenty is formulated at the full 2%.

Nothing worked until I found this. Sounds dramatic but I'm serious. On to my 7th bottle.
