GHK-Cu is a small, naturally occurring copper peptide that scientists study in the laboratory. If you have read about copper peptides and wondered what GHK-Cu actually is, this simple guide explains where it comes from, what preclinical research has looked at, and how it is handled as a research material. Everything below describes laboratory science only. GHK-Cu sold by Dissolv Labs is a research-use-only (RUO) chemical and is not a drug or a product for people.
What is GHK-Cu?
A peptide is a short chain of amino acids, which are the tiny building blocks that make up proteins. A copper peptide, or tripeptide in this case, is a peptide made of three amino acids that holds on to a copper atom. GHK-Cu is exactly that: its longer chemical name is glycyl-L-histidyl-L-lysine copper complex. The letters G, H, and K stand for the three amino acids (glycine, histidine, and lysine), and Cu is the chemical symbol for copper. So GHK-Cu means the GHK tripeptide bound to copper. Because it is so small, GHK-Cu is easy for researchers to make and study in laboratory settings.
Where does GHK-Cu come from?
GHK-Cu is not a man-made invention. GHK is a naturally occurring tripeptide found in human blood plasma, and it also appears in other body fluids. It was first isolated by biochemist Loren Pickart, who reported in the 1970s that a small fraction taken from human plasma had interesting effects on liver tissue in the laboratory. Later work by Pickart and colleagues identified that fraction as the GHK tripeptide and showed that it naturally binds copper, forming the GHK-Cu complex. Scientists have also noted that the amount of GHK in human plasma tends to be higher in younger people, which is one reason it has drawn research interest, as described by Pickart and Margolina.
What does the research say about GHK-Cu?
Most of what is known about GHK-Cu comes from preclinical research, meaning studies done in test tubes (in vitro) or in animals rather than in people. It is important to attribute each finding to the scientists who reported it, and none of these findings are promises about what GHK-Cu does in humans.
In a 2018 review in the journal Cosmetics, Pickart and Margolina summarized laboratory reports suggesting that GHK-Cu can influence pathways connected to wound repair and to the production of collagen, a structural protein, in cell and tissue studies. In an earlier 2012 review in Oxidative Medicine and Cellular Longevity, Pickart, Vasquez-Soltero, and Margolina discussed laboratory and animal findings on how the GHK-Cu tripeptide interacts with copper and with cellular pathways tied to oxidative stress. A 2020 review by Dou and colleagues in Aging Pathobiology and Therapeutics examined GHK in the context of aging-related pathways studied in preclinical models. These are review articles that gather and describe earlier experiments; they report on research directions, not proven human benefits.
Is GHK-Cu FDA approved?
No. GHK-Cu is not an FDA-approved drug. The GHK-Cu material sold by Dissolv Labs is offered strictly as a research-use-only chemical for laboratory study. It is not a medicine, not a supplement, and not intended for human or animal use. Saying that GHK-Cu is a naturally occurring copper-binding tripeptide is a plain scientific fact; it does not mean the compound has been approved or reviewed as a treatment for any condition.
How researchers store and handle GHK-Cu
GHK-Cu is typically supplied as a dry powder for laboratory work. General laboratory practice for research peptides is to keep the sealed powder cool and protected from light and moisture, and to record lot numbers for reference. Because this article is educational and GHK-Cu is a research-use-only material, it does not include any preparation steps, amounts, or methods of use. Researchers should follow their own institution's safety guidelines and the documentation that comes with the material.
GHK-Cu vs BPC-157
People researching peptides sometimes compare GHK-Cu with BPC-157, but they are different compounds studied in different areas. GHK-Cu is a three-amino-acid copper-binding tripeptide, and its preclinical literature focuses largely on copper-related pathways connected to skin, collagen, and wound repair. BPC-157 is a different, longer peptide sequence, and its separate preclinical research has mostly looked at other tissue and gut-related pathways in animal models. Both are research peptides, but they have different structures and research histories, so findings about one should not be assumed to apply to the other.

Frequently asked questions
Is GHK-Cu the same as GHK?
GHK is the plain tripeptide (glycyl-L-histidyl-L-lysine), while GHK-Cu is that same tripeptide bound to a copper atom. Researchers often study the copper-bound form because the copper appears to be part of how the peptide behaves in laboratory experiments, as described by Pickart and Margolina.
Does GHK-Cu occur naturally in the body?
Yes. GHK is a naturally occurring tripeptide reported in human blood plasma and other body fluids. This is a scientific description of where the molecule is found, not a claim about health effects.
Can I use GHK-Cu from Dissolv Labs on skin or take it?
No. GHK-Cu from Dissolv Labs is sold as a research-use-only material for laboratory study. It is not a cosmetic, drug, or supplement, and it is not intended for human or animal use.
The bottom line
GHK-Cu is a naturally occurring copper-binding tripeptide, first isolated by Loren Pickart, that has been examined in preclinical and in-vitro research connected to copper, collagen, and wound-repair pathways. It is not an FDA-approved drug, and the GHK-Cu offered by Dissolv Labs is a research-use-only material that is not for human or animal use.
