Details
What it is
The tripeptide glycine-histidine-lysine complexed with copper(II). GHK occurs naturally in human plasma, where its concentration falls with age, and it binds copper with a high enough affinity to take it from albumin. The blue colour of the powder is the copper complex, not a dye.
Also sold as: copper tripeptide-1, GHK-copper, glycyl-histidyl-lysine copper
- As suppliedLyophilised powder, research grade. Deep blue.
- Into solutionWater-soluble.
Class: Copper tripeptides.
Third-party testing
Our supplier sent samples of this line to Janoshik, an independent analytical laboratory. Enter the task number and key at janoshik.com/verify to read the report on the laboratory's own site, not a copy from us.
These results are for the sample the supplier submitted. They are not a result for the lot you receive, and where a report names a strength, it covers that strength only. See how to read a certificate of analysis.
Reconstitution and handling
Handling
- As suppliedLyophilised powder
- Sealed, refrigeratedMonths
- In solutionRefrigerate, use short-term
Concentration is mass divided by the volume you added. A 50mg vial made up to one millilitre of solvent gives 50mg per millilitre; to two millilitres, half that. Record the volume you used: a solution whose concentration is not written down is a solution you cannot use quantitatively.
The full procedure is on our reconstitution guide, with a concentration calculator; what is known about keeping these materials is on storage and stability. Bacteriostatic water and acetic acid are both in our catalogue and can be ordered with a product or on their own.
