GHK-Cu pricing across our tracked vendors ranges $2.10 (cheapest) to $16.99 (most expensive) — a 710% spread for what should be the same compound. Median is ~$5.40. That's a huge spread, which usually means the cheapest vendor is either passing on bulk-buying advantage or cutting corners on QC. Always cross-check the cheapest vendor's COA before ordering. Cheapest vendor changes ~weekly based on restocks and discount cycling.
Why this page exists
Peptide prices vary wildly between vendors — sometimes by 3x or more for the exact same compound at the same purity. Vendors use different quantity sizes to obscure comparisons. PeptidePrices normalizes every mg-denominated listing to a 10mg equivalent so you can compare unlike vial sizes on the same basis.
How we rank: Only in-stock listings are shown. Prices are deduplicated per vendor (cheapest variant only). Non-normalized listings (missing quantity data) are excluded. See our full methodology.
