GHK-Cu is currently in stock at 63 shops, all of which have third-party lab tests on file. Prices range from $12.00 to $197.00 per vial, with a median of $0.600 per mg. Vial sizes range from 2mg to 200mg. Last updated 11 September 2026.
256 shops are known to sell GHK-Cu — 68 with a live listing, 188 evidenced by a lab test in the last year. 108 listings are identified, of which 90 can be compared per milligram.
Bigger vials cost less per milligram. The vial, freeze-drying, labelling, lab test and shipping cost roughly the same whether it holds 5mg or 100mg, so per-milligram price falls as fill size rises. Compare within your size band rather than across the whole list.
