Prices are for research materials sold for laboratory use only. PeptidePub may earn a commission from vendor links or codes at no cost to you. This does not affect testing grades or rankings. See our methodology. Best value is the lowest $/mg among vendors with verifiable published testing; Best tested is the vendor passing the most of our 7 testing checks.
Which size should I buy?
Bigger vials cost less per mg. Right now the cheapest 1000 mg option is $0.05/mg, about 81% less per mg than the cheapest 50 mg option at $0.27/mg.
The saving only counts if you can use the vial within its storage window. This peptide's guide lists a reconstituted use-within window of 30 days. See handling and storage.
Smaller vials cost more per mg but waste less if a vial sits open past its window. Filter to 50 mg and Filter to 1000 mg.

What's the cheapest GHK-Cu?
The cheapest GHK-Cu right now is $0.05/mg at Certified-Pep for the 1000 mg option, after code peptidepub.
How is GHK-Cu price per mg calculated?
PeptidePub normalizes each vial by dividing the effective checkout price by the listed size in mg. That lets different vial sizes sit in one cheapest-first comparison.
Are discount codes included in these prices?
Yes. When a vendor has a confirmed code percent in the catalog, PeptidePub applies that discount before calculating effective price and effective price per unit. Codes without a confirmed percent are shown, but they are not used to lower the calculated price.
How often are prices updated?
The catalog is refreshed daily from vendor data sweeps, and the page reflects the current catalog values at build time. When vendor pricing or codes change, the comparison and cheapest-offer answer update from the same source data.
