The order is the editors' score, not the price, because the cheapest untested vial is not a bargain. The listing shown is each shop's 50 mg single-vial price, the size most shops carry; where a shop does not stock that size we show its nearest listing and say so. Prices were read during our October 2026 check, before coupons and shipping. Every listing is sold for laboratory research use only.

Questions
Who is the best GHK-Cu supplier?
Licensed Peptides, on our formula: 8.2 out of 10, the highest score among the 41 shops that list it. Licensed Peptides names two accredited laboratories and keeps three separate document libraries, which puts it near the top of our index for paperwork. The score is the same one we give the shop everywhere on this site; nothing is reweighted for the peptide.
Who sells GHK-Cu cheapest at 50 mg?
Trident Peptide UK, at $20.26 for 50 mg against a typical $49.50. It scores 3.1, below the 6.5 we like to see before calling a low price a bargain. The price page lists every size and every shop.
Which GHK-Cu suppliers show a certificate on the product page?
18 of the 41: Licensed Peptides, Ascension Peptides, Paramount Peptides, Core Peptides, Koi Peptides, Sports Technology Labs, Evolve Peptides and Alpha Labs Peptides and 10 more. A certificate on the page is the least a shop can do; a lot number on it that matches the vial is the thing to check, and our lab-report guide shows how in five minutes.
