Cheapest GHK-Cu price FAQ
What's the cheapest GHK-Cu?
The cheapest GHK-Cu right now is $0.04/mg at Atomik Labz for the 1000 mg option, after code PEPTIDEPUB15.
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.
Used in pets?
Chronic wounds, post-surgical healing, skin and coat quality. Frequently used topically as well as by injection.
How it's given: Topical on wounds/skin, or subcutaneous.
Educational, not veterinary advice. No controlled trials exist in pets; avoid in animals with active cancer. Work with your vet.
Formulated & specialty options
Ready-made blends and formulated products that include GHK-Cu. Priced per product, not per milligram, so they sit outside the raw comparison above.
