Manufacturer statement
The product page shows no product-specific COA link for GHK-CU 50mg; the COA archive page lists a separate GHK-CU 100mg Janoshik test link and the site claims batch verification / quality checking in general.

I found a public independent Janoshik report on the supplier’s COA archive, but it is for TB-500 10mg, not the GHK-CU 50mg listing. The product page itself does not expose a product-specific COA for the listed vial size, so there is no direct analytical evidence for this exact item.
