It occurs naturally in human blood plasma, where its apparent job is to carry copper to the cells that need it and to signal that tissue has been injured.\n\nOne disclosure, because it should change how you read the rest. The operator of this site has a commercial interest in compounds described here. That is a reason to weigh what is on this page against the sources it cites rather than against its tone, and every claim below carries the source that supports it for exactly that reason.\nTwo facts frame everything else here. The first is that the peptide runs out. Plasma GHK measures about 200 ng/mL at age 20 and falls to about 80 ng/mL by age 60 — a 60% decline across four decades, reported in the same terms in two separate reviews.\n\n[[embed:source:s2]]\n\n[[embed:source:s4]]\n\nThe second is that GHK-Cu is one of the few compounds in this library with a genuine human evidence base, because it spent thirty years as a cosmetic ingredient rather than a research chemical. That evidence is entirely topical. Injected GHK-Cu, which is how most people discussing it online are using it, has no completed human trial of any kind.\n\n## Copper is the cargo, and copper is also the hazard\n\nStrip the peptide away and what GHK-Cu delivers is copper in a form a cell can accept. Copper is a required cofactor for roughly a dozen enzymes. Two of them explain most of the interest in this molecule.\n\nLysyl oxidase is the enzyme that cross-links collagen and elastin. Newly made collagen is soft, soluble and mechanically useless until lysyl oxidase welds the strands together; without copper the enzyme never activates, and connective tissue never gains tensile strength. Copper-zinc superoxide dismutase is the other — the main enzymatic defence against superoxide inside a cell.\n\nThe activation step is physically specific. Lysyl oxidase acquires its copper inside the Golgi apparatus, and a 2026 delivery study built its entire design around that fact, using GHK-Cu as the copper source feeding a Golgi-targeted system. Lysyl oxidase activity rose to 1.78 times control, and collagen alignment improved in a rabbit fascia defect.\n\n[[embed:source:w_bmq20ziw]]\n\nThat is the upside. The downside is that copper is a heavy metal with a narrow useful range, and injecting it bypasses the one organ that regulates how much of it enters the body. Dietary copper absorption falls from about 75% when intake is low to about 12% when intake is high — the gut throttles itself. A subcutaneous injection does not.\n\nThe arithmetic is worth doing rather than gesturing at. Copper tripeptide-1 has the formula C14H23CuN6O4+ and a molecular weight of 402.92 g/mol. Copper's atomic weight is 63.546. Copper is therefore 63.546 ÷ 402.92 = 15.77% of the mass of the complex.\n\n[[embed:source:w_h4l8y6l7]]\n\n| GHK-Cu dose | Elemental copper delivered | Share of the 900 mcg adult RDA | Share of the 10,000 mcg upper limit |\n|---|---|---|---|\n| 0.5 mg | 79 mcg | 9% | 0.8% |\n| 1 mg | 158 mcg | 18% | 1.6% |\n| 2 mg | 315 mcg | 35% | 3.2% |\n| 3 mg | 473 mcg | 53% | 4.7% |\n| 5 mg | 789 mcg | 88% | 7.9% |\n\nThe upper limit is an oral figure, set on the basis of liver damage, and it assumes intestinal regulation is working. Read the right-hand column as reassuring and the calculation has been misread. Read the third column instead: 3 mg daily by injection adds roughly half an adult's entire daily copper requirement, unregulated, on top of diet.\n\n[[embed:source:w_mt4pif88]]\n\nWilson's disease is a hard stop. It is an autosomal recessive mutation in ATP7B that leaves the body unable to clear copper; untreated it produces cirrhosis, acute hepatitis, haemolytic crisis and neurological damage, and treatment is lifelong copper chelation. Giving a copper delivery vehicle to someone with Wilson's disease means giving them the exact substance their disease cannot handle.
