Supplier comparison
GHK-Cu, uncomplexed GHK and finished cosmetic formulations are not the same comparison category. This page focuses on supplier listings identified as research GHK-Cu material. This comparison is for laboratory research and is not a product recommendation.
Compare exact listings ↓What matters for GHK-Cu
1. Confirm the material
Confirm that the record identifies the copper complex rather than GHK alone, along with the expected peptide identity and labeled amount.
2. Compare the same quantity
Common 50 mg and 100 mg listings should be compared separately or by price per mg. Formulated products should not be mixed with raw research material.
3. Connect the evidence
Review peptide identity, copper or complex information, purity, measured content and the lot-to-report connection.
Each price is tied to a specific vial size. Price per mg is calculated from the amount printed on the listing.
A general report library is distinguished from documentation connected to the exact product and current offered lot.
The lowest price is not treated as the strongest documentation, best supplier, or evidence of product identity or suitability.
For laboratory research only
Listings now default to lowest tracked price per mg. The highlighted price badge is a catalog-price signal only, not a quality, safety, or documentation ranking.
The document count covers six basic checks. “Not found” means we could not confirm it from the public records we reviewed—not that the testing never happened.

How to use this page
First confirm that the listing names the intended molecule, form and vial quantity. Then inspect whether the available analytical record connects the product, lot, laboratory, method and result.
Public discount estimates are shown only when PDD has a documented percentage. Shipping, tax, minimum-order conditions and later catalog changes can alter the final cost.
Before procurement, verify the live listing and request current-lot records when the public evidence does not establish that connection.
Evidence boundary
Documentation coverage describes what PDD located in public records. It is not proof of safety, efficacy, authenticity, sterility, regulatory compliance or suitability. Affiliate compensation does not change inclusion, evidence states or default ordering.
No. The copper complex and uncomplexed peptide are analytically distinct and should not be silently combined.
Not directly. Finished formulations introduce additional ingredients, concentrations and product specifications.
It does not capture copper content, formulation, shipping, tax or the strength of the supporting documentation.
