GHK-Cu price comparison

Eros Peptides currently lists GHK-Cu at $0.25 per mg (GHK-Cu 100MG, $24.99), the lowest of the 52 vendors we compare. The median is $0.59 per mg, so shopping around can save a lot.

Across 52 vendors, injectable GHK-Cu ranges from $0.25 to $1.70 per mg, with a median of $0.59. Larger vials generally cost less per mg, which is why we normalize every listing to a price per milligram.

A 50 mg vial of GHK-Cu costs between $14.99 and $84.97 across 41 vendors, with a median of $38.50. The cheapest is Eros Peptides at $14.99.

50 of the 61 vendors listing GHK-Cu say they publish certificates of analysis (COAs). A COA is the vendor’s own claim and can be copied or re-dated, so we also show independent test ratings (Finnrick) on each vendor page where they exist, and let you filter to “COA claimed” vendors.

We also track capsules, other oral, sprays, tablets listings for GHK-Cu. They are priced per mg of active ingredient too, but usually cost more per mg than lyophilized vials. Use the form filter above to compare them.

PubMed lists 150 papers on GHK-Cu: 1 randomized controlled trial, 3 human clinical studies and 29 animal or lab-only studies, plus 4 registered clinical trials. We grade the evidence base as “Moderate”: At least one randomized trial or a meaningful body of human studies, but not a deep trial base. This describes how much research exists, not whether it works.
