How Much Does GHK-Cu Cost in 2026?

GHK-Cu — the copper tripeptide — reads as one of the cheapest peptides on a per-milligram basis, and that's largely a dosing artifact. It's handled in tens to hundreds of milligrams, not the microgram-to-single-milligram amounts that make peptides like BPC-157 look expensive, so the per-mg number lands low: roughly $0.40 to $0.68 per mg across research vendors in mid-2026.

Because per-mg looks so small, per-vial context matters more here. A single 50 mg vial runs about $32, single 50–100 mg vials sit at $0.55–$0.68/mg, and the big multi-vial or gram-scale kits push the effective cost down to about $0.40/mg. This is research-vendor pricing for the injectable/subQ material sold 'for research use only' — not the price of a cosmetic serum and not a treatment cost.

The main lever is order size. GHK-Cu synthesis, lyophilization, shipping, and cold-chain handling are largely fixed costs, so spreading them across more total milligrams is what drops the effective price. A single 50–100 mg vial lands near the top of the range ($0.55–$0.68/mg), while large multi-vial and gram-scale kits bottom out around $0.40/mg. Convert every listing to dollars-per-milligram before comparing — but with GHK-Cu, also sanity-check the per-vial figure, because a low per-mg number can hide a large minimum order.

The second lever is testing, and it's the reason we only surface vendors that publish independent third-party Certificates of Analysis (COAs) for the actual batch you're buying. It's worth being precise about which GHK-Cu you're pricing: 'Copper Tripeptide-1' is a regulated topical cosmetic ingredient found in skincare, while the injectable/subQ GHK-Cu priced on this page is sold strictly for laboratory research use — the two are the same molecule but are not interchangeable products, and only the research material carries a batch COA showing identity and purity.
