Description
GHK-Cu copper peptide from Sports Technology Labs is a sterile glass vial holding 50mg of GHK-Cu as freeze-dried powder. GHK-Cu is a copper-binding tripeptide. It’s sold for laboratory research only.
Background on GHK-Cu
GHK-Cu is the tripeptide glycyl-L-histidyl-L-lysine bound to a copper(II) ion. Loren Pickart first isolated GHK from human plasma in 1973, and levels in plasma are reported to fall with age.
It binds copper tightly and is studied for wound healing, collagen production and skin repair. It’s also one of the most common actives in copper peptide skin care.
What GHK-Cu does in cells
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.

What the literature says about GHK-Cu
Maquart and colleagues reported in 1988 that GHK-Cu stimulated collagen synthesis in cultured fibroblasts, and later rat wound-chamber studies found more collagen and glycosaminoglycan buildup.
Gene expression work by Pickart and colleagues suggests GHK can shift the activity of a large number of human genes, many tied to tissue repair and the antioxidant response.

Where GHK-Cu fits in the range
Quick context: GHK-Cu is a copper-binding tripeptide linked to collagen and wound remodeling. Other compounds in the same area:
- BPC-157 is a 15-amino-acid fragment of a gastric protein, studied for new blood vessel growth and tissue repair
- TB-500 is synthetic thymosin beta-4, an actin-binding peptide tied to cell migration
- KPV is the three-amino-acid tail of alpha-MSH, studied for calming inflammation
- PEG-MGF is a pegylated splice variant of IGF-1 studied in muscle repair
They map onto different stages of repair: new blood vessels, cell migration, inflammation and rebuilding the tissue matrix. Compare them in our healing and recovery peptides.
How Sports Technology Labs tests GHK-Cu copper peptide
The current certificate of analysis shows 99.40% by HPLC. The testing is done by MZ Biolabs, an independent lab in Tucson, Arizona, which also checks identity by mass spectrometry.
The COA image is in the product gallery at the top of this page, so you can read the batch result before you order.
HPLC and mass spec answer different questions. HPLC tells you what share of the sample is the main compound. Mass spec tells you the compound is the right molecule. A COA with only one of them leaves a gap.
You also get a 60-day money-back guarantee on the order.
GHK-Cu copper peptide mixing guide
The vial holds 50mg of freeze-dried powder. Divide that by the millilitres of diluent you add and you have the concentration:
- 2mL of diluent gives 25mg per mL
- 3mL of diluent gives 16.667mg per mL
- 5mL of diluent gives 10mg per mL
Diluent isn’t included, and most labs use bacteriostatic water. Let the vial reach room temperature, swab the stopper and let the liquid run slowly down the glass. Swirl, don’t shake, until it’s clear.
Keeping GHK-Cu copper peptide stable
Before mixing, store GHK-Cu copper peptide at 2 to 8°C in its box. After reconstitution it stays in the fridge too, and most labs use it up within 30 days. Freezing the solution isn’t recommended.
Mix one vial at a time. Powder keeps for months, solution for weeks.
