What is GHK-Cu?
GHK-Cu is a copper-binding tripeptide made of three amino acids, glycine, L-histidine and L-lysine, holding a single copper(II) ion. Put simply, it is the copper tripeptide: one small peptide carrying one atom of copper. It occurs naturally in the human body and is one of the most studied peptides in skin and tissue research. It is supplied strictly for laboratory and educational research.

What makes GHK-Cu unusual is that it is not a synthetic invention. It occurs naturally in human blood plasma, saliva and urine. It was first isolated by Dr Loren Pickart in 1973, who noticed that a fraction of human plasma could make aged liver tissue behave more like young tissue in the laboratory. The active fraction turned out to be GHK.
How GHK-Cu is thought to work
GHK-Cu is best understood as a signalling and delivery molecule. Research points to a few overlapping mechanisms that are studied together rather than in isolation.
Mechanisms studied in the research
- Copper delivery: copper is a cofactor for enzymes involved in building and cross-linking collagen and elastin, the proteins that give skin its structure and bounce. GHK has a very high affinity for copper and shuttles it to where cells can use it.
- Stimulating the matrix: in laboratory studies GHK-Cu has been shown to stimulate the production of collagen, elastin and glycosaminoglycans, the cushioning molecules in skin, and to support the fibroblasts that manufacture them.
- Resetting gene expression: published gene-profiling research suggests GHK may shift the activity of many human genes toward a more youthful pattern in laboratory models, associated with repair pathways and with lower inflammatory and stress signalling.
- Antioxidant and anti-inflammatory activity: GHK-Cu has been studied for its ability to neutralise reactive oxygen species and to calm inflammatory signalling, both central to how tissue recovers from damage.
The systems-level effect is what excites researchers most, because it goes beyond a single target. Imagery and illustrations used in our materials are for educational purposes only.
GHK-Cu and skin
Skin is where the copper peptide earned its reputation. Across published research, GHK-Cu has been studied for a cluster of related effects.
What the research has looked at
- Studied for its effect on collagen and elastin production and on skin firmness and elasticity
- The look of fine lines and skin thickness in ageing and photodamaged skin
- The skin barrier and overall skin density and tone
- The appearance of damage from sun exposure and oxidative stress
This is why GHK-Cu became a staple ingredient in serious cosmeceutical formulations long before the current peptide wave. The same properties studied for skin repair after injury are the ones associated with smoother, firmer, healthier looking skin over time. In a research context, GHK-Cu is studied both as a topical and as a reconstituted peptide.
GHK-Cu and hair
The copper peptide is also studied in hair research. GHK-Cu has been observed to enlarge hair follicles and extend the growth phase of the hair cycle in laboratory and animal models, and copper peptides have been investigated for their effect on follicle size and the appearance of thicker hair.
Because the same repair and matrix-building pathways are involved, hair is a natural extension of the skin research, and it is one of the reasons GHK-Cu shows up so often in peptide discussions. It remains an area of investigation, not a promised outcome.
Tissue repair and recovery
Beyond skin and hair, GHK-Cu has a long history in wound healing research. Studies have looked at its role in attracting repair cells to a site of injury, supporting the formation of new blood vessels (angiogenesis), and improving the quality of healed tissue in laboratory and animal models.
This regenerative angle is exactly why GHK-Cu pairs so naturally with recovery peptides in a research blend, and it sets up the logic behind GLOW.
GHK-Cu in the GLOW blend
At NovaPeptides, GHK-Cu is the lead peptide in GLOW, our regenerative research blend. Rather than GHK-Cu on its own, GLOW combines three peptides that are each studied for skin, recovery and tissue repair, so the research story is broader than any single one.
What is in GLOW
- GLOW total: a 70mg regenerative peptide blend
- GHK-Cu: the copper peptide, studied for skin, collagen and repair
- BPC-157: a body-protection peptide studied for tissue and gut repair
- TB-500: a thymosin fragment studied for recovery and flexibility
The idea behind a blend is synergy: GHK-Cu brings the copper-driven skin and collagen research, while BPC-157 and TB-500 add their own well-studied recovery and repair profiles. Together they make GLOW one of the most complete regenerative research kits we offer. Researchers can enquire about GLOW via WhatsApp; supplied for research use only.
Research handling and reconstitution
GHK-Cu and the GLOW blend ship as a lyophilised (freeze-dried) powder. In a research setting it is reconstituted with bacteriostatic water before use. For GLOW, reconstituting the 70mg blend with 3mL of bacteriostatic water gives a working concentration where each 0.01mL click on a U-100 pen delivers about 0.23mg of the blend.
We keep the complete calculations, including how the 70mg GLOW blend converts to clicks on a U-100 pen, on our interactive pen and dosing guide. It is provided for research reference only and is not a recommendation for human use.
Purity and testing
With copper peptides, quality is everything, because identity and purity determine whether research is meaningful. Every NovaPeptides batch, including the GHK-Cu in GLOW, is independently tested and documented on a verifiable Novagen Laboratories Certificate of Analysis, and ships with a verifiable Certificate of Analysis for purity, content and identity.
No smoke, no mirrors. Each batch is independently verified for purity, content and identity. Ask us and we will send the report.
This lab-proof transparency, rather than any named expert or treatment claim, is how we stand behind the catalogue. Content is prepared by the NovaPeptides Research Team using research and education references.
Verified by Novagen Laboratories
Every NovaPeptides batch, including the GHK-Cu in the GLOW blend, ships with a verifiable Novagen Laboratories Certificate of Analysis covering identity, content and purity. Each certificate carries a unique key so you can confirm it is genuine yourself.
Verify any batch yourself
No smoke, no mirrors. Copy the unique key printed on the COA, enter it at Novagen Laboratories, and the certificate is confirmed as genuine. Ask us on WhatsApp and we will send the report for your current batch.

At NovaPeptides, GHK-Cu is supplied within the GLOW blend as a complete, ready-to-assemble research kit rather than a loose vial, with the reusable dosing pen, bacteriostatic water, needle heads, an extraction syringe and a thermal hard case, plus a verifiable Novagen Laboratories Certificate of Analysis. Because the right concentration depends on how much bacteriostatic water you reconstitute with, we keep the click-by-click method on a U-100 pen in one place.
