Description
GHK-Cu 50mg from Blue Sky Peptide is 50mg of GHK-Cu in a sealed glass vial. GHK-Cu is a copper-binding tripeptide. This batch tested at 99.96% purity. It’s for in-vitro and lab research only.
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.
How GHK-Cu acts in the lab
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 research says about GHK-Cu
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.

How GHK-Cu compares
Labs choosing GHK-Cu 50mg usually weigh it against a few close relatives. GHK-Cu is the copper-binding tripeptide studied for collagen and skin repair, while:
- BPC-157 is the 15-amino-acid repair peptide with the largest body of rodent research
- TB-500 is the 43-amino-acid actin-binding protein, studied for cell movement and wound repair
- KPV is a three-amino-acid alpha-MSH fragment studied for calming inflammation
- ARA-290 is an 11-amino-acid peptide from erythropoietin that protects tissue without raising red cells
These are the main peptides in repair research. Each covers a different step, from blood vessel growth and cell movement to calming inflammation and rebuilding the skin matrix. See them all on our healing and recovery peptides page.
Reconstituting GHK-Cu 50mg
Here’s the math for 50mg of peptide:
- 2mL of water gives 25mg/mL
- 3mL of water gives 16.67mg/mL
- 5mL of water gives 10mg/mL
Go with whichever number is easiest to work with in your protocol, and label the vial with the concentration and the date you mixed it.
Most labs use sterile bacteriostatic water. Let the vial reach room temperature, run the water slowly down the inside of the glass, then roll the vial gently until the powder dissolves. Don’t shake it. Shaking can shear peptide chains.
Storing GHK-Cu 50mg
Freeze-dried GHK-Cu 50mg is stable at room temperature for shipping, but for anything longer keep it in a freezer at -20°C, away from light. Once mixed, keep it in the fridge at 2 to 8°C and use it within about four weeks.
If you keep several vials going at once, our vial storage case holds ten upright with room for labels, and the hard storage box protects them in a shared freezer or in transit.
GHK-Cu 50mg quality and batch records
Our GHK-Cu 50mg batch measured 99.96% pure by HPLC with mass spectrometry confirming the identity. We print the real number, so you know what’s going into your experiment.
Every vial is labeled with the compound, the amount and the batch. If your lab keeps paperwork on file, email us the batch number from the label and we’ll send the certificate of analysis for it.
If a result looks off, check the batch number first, then your handling notes. Most problems with GHK-Cu come from storage or mixing, not the material.
