GHK-Cu Raw Powder (1 Gram)

Description

Our GHK-Cu raw powder gives you 1,000mg of GHK-Cu in one container, for topical formulation work 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.

GHK-Cu research

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 50mg costs $35.00 for 50mg, about $0.70 per mg. GHK-Cu raw powder is $30.00 for 1,000mg, about $0.03 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%.

Storing GHK-Cu raw powder

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. Solutions you make from it belong in the fridge at 2 to 8°C, used within 28 days.

GHK-Cu raw powder purity and lab testing

GHK-Cu raw powder goes through HPLC-MS before it’s sold. Chromatography gives the purity figure, and the mass spectrometer checks the molecular weight against the expected value. GHK-Cu raw powder tests at over 99% purity.

After freeze-drying, each container is vacuum-sealed. Keeping air and moisture out is what lets lyophilized peptide stay stable for months in a freezer.

If you run a long study, try to keep it on one batch and log the number from the label. It removes one variable from your results.

Common questions about GHK-Cu raw powder

How pure is GHK-Cu raw powder?

Over 99% by HPLC-MS. The same test confirms the molecular weight, so it checks identity too.

How much is in GHK-Cu raw powder?

1 gram, which is 1,000mg of powder.

Is this the same compound as the vial?

Yes. It’s the same GHK-Cu, sold loose in a larger amount instead of portioned into a vial.

Is GHK-Cu raw powder in stock?

Yes. GHK-Cu raw powder is in stock and ready to ship.

Is there a bulk discount?

Yes. Choose 2, 10 and 20 grams in the Quantity menu and save between 10% and 20% per gram.
