GHK-CU
Tax included where applicable. Shipping calculated at checkout.
GHK-Cu is a naturally occurring copper-binding tripeptide found in human plasma, with levels declining 60% between age 20 and 60. At nanomolar concentrations, it stimulates collagen synthesis, wound healing, and blood vessel formation. Gene profiling revealed it modulates over 4,000 human genes towards a healthier expression pattern.

Research Overview
About this compound
What does the research say?
GHK-Cu is a naturally occurring tripeptide (Gly-His-Lys) with a high affinity for copper(II) ions. It was first isolated from human plasma in 1973. At age 20, plasma GHK levels average about 200 ng/ml, but decline to approximately 80 ng/ml by age 60. This decline coincides with the noticeable decrease in the body's regenerative capacity.
At concentrations as low as 1 nanomolar, GHK-Cu stimulated synthesis of collagen, dermatan sulfate, chondroitin sulfate, and decorin. It accelerated wound healing and increased blood vessel formation in multiple animal models. GHK-Cu also restored viability to fibroblasts damaged by anticancer radiation therapy. Gene expression profiling revealed that GHK modulates the activity of over 4,000 human genes, with a clear pattern of resetting gene expression towards a healthier state.

Why does quality matter with GHK-Cu?
GHK-Cu is a copper-peptide complex. The copper(II) ion must be properly chelated to the peptide for biological activity. Products with incorrect copper ratios, free copper, or degraded peptide will not replicate the published effects.
At Camo Chem, every batch is tested by an independent 3rd party laboratory. We publish the full Certificate of Analysis for every batch, and you can verify the results directly with the lab. We do not self-certify. Ever.

FAQ
Frequently asked questions
GHK-Cu is a naturally occurring copper-binding tripeptide (Gly-His-Lys:Cu) with CAS number 89030-95-5. First isolated from human plasma in 1973, it has been studied for nearly five decades for its role in tissue remodelling, wound healing, and gene expression regulation. It is sold exclusively as a research compound.
Every batch meets a minimum of 98% purity as verified by HPLC. Testing is performed by an independent 3rd party laboratory. The CoA is available on this page.
By an independent laboratory with no commercial relationship with our company. We do not self-certify. Our CoAs are verifiable directly with the testing lab.
Yes. GHK-Cu is supplied as a lyophilised powder and must be reconstituted before use. It may show limited solubility in bacteriostatic water; sterile water is an alternative.
In lyophilised form, store in a cool, dry place. After reconstitution, refrigerate at 2-8°C.
