Buying GHK-Cu in the US (2026): price per mg, vial sizes, how to verify the lot
GHK-Cu is listed in 2 vial sizes (50 mg, 100 mg); the lowest price per labelled mg for a single vial is $0.59 on the 100 mg vial, and a 10-vial kit brings that size to $0.53 per mg. Every listed size has a Janoshik report you can confirm with the lab directly using its verify key.

Price per mg by vial size
Price per mg is the listed price divided by the labelled vial content. It is arithmetic, not a measurement: the assayed net content of each lot is on its report, below.
Prices are the catalogue prices at the time this page was built. Any sitewide promotion is applied at checkout and is not reflected here.
Kit or single vial
A kit is 10 vials of the same size sold as one item at one price. A single vial is one vial.
- 50 mg: 10 single vials would be $450 at list price; the kit is $405 (10% less than 10 singles at list price).
- 100 mg: 10 single vials would be $590 at list price; the kit is $531 (10% less than 10 singles at list price).
How to verify our Janoshik report yourself
- Find the verify key for the size you are buying in the card below (it is also printed on the report).
- Go to janoshik.com/verify and enter the key.
- Check that the report the lab returns matches the card: task number, sample name, assayed purity and net content.
- If anything differs, do not rely on our copy. The lab's record is the authority, not this page.
