GHK-Cu prices
246 sellers, 408 listings, 16 vial sizes, read from each store's public product feed on 2026-10-30. A seller with a recent certificate from a named lab ranks above a cheaper one without. Every card says why it sits where it does.
50 public certificate files we opened name GHK-Cu. That is a count of files, not a grade, and compounds are not ranked against one another. A seller-published certificate is not a blind test. Certificate search.

Some seller links may pay this site when you buy through them. A payment never changes a seller's tier or rank, and no seller has a say in any page.

The figure is the same ungated market median the range on this page uses: every seller found. Certificate tier still ranks the cards. The purity gate is written and off, so this is not a tested-sellers-only series.
How the ranking works
- LC
- Lab-confirmed: the issuing laboratory echoed this certificate back
- A
- Current certificate, independent laboratory named, laboratory not yet checked
- B
- Certificate published, but no laboratory link, older than a year, or the laboratory did not recognise the published lookup
- C
- No certificate could be read
- Grade first, then price per milligram within the grade. A cheap vial that is not the real compound is not cheap, so no price moves a seller above a better certificate. Sort by price if you want price alone. The grade stays on the card.
- The grade is what we could read on the seller's site on the date shown, not what the seller claims. If a login page or a robot block hid the certificates, the card says so. A later check in a normal browser may raise that grade.
- Prices are list prices before any discount code, shipping, tax or customs. Multi-vial packs are counted at their total milligrams, and their per mg price reflects that.
- The dot on each card shows where that price sits between the cheapest and the priciest seller of the same vial. The tick is the middle price. A bigger vial's lower price per mg is never mistaken for a better seller.
- Every seller links to its own page: the company behind it, address, store platform, labs named, a sample certificate, shipping and payment terms, and every warning sign we found.
We never charge for knowledge. No vendor has a say in what a page says. Sellers are ranked by the certificate they publish, then by price. Every seller, graded · Laboratories named · How this is counted
