Description
GHK-Cu raw powder is 1 gram (1,000mg) of GHK-Cu as a dry powder, made in the USA for formulation and lab research. It isn’t for human or veterinary use.
GHK-Cu is the most common active in copper peptide serums and creams, so formulation labs buy it in gram amounts to make test batches.
About GHK-Cu
GHK-Cu is the tripeptide glycyl-histidyl-lysine bound to a copper ion. GHK occurs naturally in human plasma, saliva and urine, and its levels fall with age.
It’s used widely in skin and wound research, and in cosmetic formulas.
GHK-Cu mechanism
GHK binds copper tightly and can deliver it to cells. Copper is a cofactor for lysyl oxidase, the enzyme that cross-links collagen and elastin, and for antioxidant enzymes.
In cell and animal studies GHK-Cu increased collagen and glycosaminoglycan production, attracted repair cells to wounds, and changed the activity of many genes involved in tissue remodeling.
Published GHK-Cu studies
Loren Pickart, who first isolated GHK in 1973, has published reviews of its effects on collagen synthesis, wound contraction and gene expression in cell and animal studies.
Maquart and colleagues reported that GHK-Cu increased collagen in rat wound chambers.

Why buy GHK-Cu as raw powder?
Price, mostly. GHK-Cu 100mg costs $59.00 for 100mg, about $0.59 per mg. GHK-Cu raw powder is $58.00 for 1,000mg, about $0.06 per mg. If you need more than a vial or two, the raw powder is far cheaper.
Raw powder also lets you set your own concentration and choose your own base, whether that’s water, a serum or a cream. A pre-filled vial fixes those choices for you.
Handling GHK-Cu raw powder
Weigh it on an analytical balance in a dry room. Fine peptide powders pick up moisture and static fast, so open the container only for as long as you need, and close it straight away. GHK-Cu and AHK-Cu are blue, a color that comes from the bound copper, and they dissolve readily in water.
Work out your target concentration before you weigh anything. For example, 10mg in 10mL of water gives 1mg/mL, which is 0.1%. Most cosmetic formulas use peptides well below 1%.
GHK-Cu raw powder storage
Keep the powder sealed in the freezer at -20°C, away from light and moisture, with a desiccant if you have one. Let the container warm to room temperature before opening it so no condensation forms on the powder.

Lab-tested GHK-Cu raw powder
We only sell U.S.-made products, and GHK-Cu raw powder is no exception. Each batch is tested by an outside U.S. lab for identity, content and purity, with a 99%+ HPLC purity standard.
You don’t have to take our word for it. The certificate of analysis for the current batch is in the image gallery at the top of this page, next to the product photo, and it shows the test date and the results.
On top of purity, each batch is screened for endotoxins, heavy metals and sterility. For cell culture work that screen is often the more important number.
