Cheapest Copper Peptide Serum Per Millilitre
Share
Bottle prices in this category range from $12 to $150, and the sizes range from 15ml to 150ml. Comparing sticker prices tells you almost nothing.
Here is cost per millilitre, with the disclosed concentration next to it, because those two numbers only mean something together. We sell one of these and we are not the cheapest.

Why the cheapest is not the cheapest
COSRX tops the table at $0.17 per ml and does not state a concentration. Good Molecules is second at $0.40 and states 5 ppm, which is 0.0005%.
Compare that against a product stating 1%, which is 10,000 ppm. On disclosed figures, Good Molecules is 2,000 times more dilute. Per unit of copper peptide rather than per millilitre, the ranking inverts almost completely.
This is the trap. The cheapest product per ml can easily be the most expensive per unit of the thing you came for, and you can only see that when concentration is stated. For six of the products above you cannot make the calculation at all.
The value picks, honestly
Best value with a disclosed concentration: The Ordinary at $1.07 per ml with 1% in the name and a published pH. Nothing else combines that price with that level of disclosure.
Best value at a high concentration: Neurogan at $0.92 per ml and a stated 4%, which is the cheapest per ml of any product stating above 1%. Note that higher is not linearly better and 4% makes cycling mandatory rather than optional.
Cheapest entry into the category: Good Molecules at $12, provided you understand you are buying a multi-peptide serum with a trace of copper rather than a copper peptide treatment. Their own page tells you that, which is more than most manage.
Where we sit
$2.00 per ml, ninth of fourteen. Roughly double The Ordinary. What you get for it is an unambiguous 1% GHK-Cu, a single stated pH of 6.0, an aqueous silicone-free base and amber glass. Whether that is worth the difference is a judgement we are obviously not neutral on, and the table above lets you make it without us.
