Dihexa vs GHK-Cu (Copper Peptide)
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Dihexa
Dihexa is a nootropic peptide derived from angiotensin IV. It has shown remarkable cognitive-enhancing properties in animal studies, being described as potentially millions of times more potent than BDNF.

GHK-Cu is a naturally occurring copper peptide found in human plasma, saliva, and urine. It plays important roles in wound healing, tissue repair, and has shown anti-aging properties in research.
Full details →Side-by-Side Comparison
| Aspect | Dihexa | GHK-Cu (Copper Peptide) |
|---|---|---|
| Mechanism | Acts as a hepatocyte growth factor (HGF) potentiator by binding to its receptor c-Met. Promotes synaptogenesis, neuronal survival, and cognitive enhancement through this pathway. | Attracts immune cells and fibroblasts to wound sites, stimulates collagen and glycosaminoglycan synthesis, promotes angiogenesis, and has antioxidant effects. Modulates gene expression related to tissue repair. |
| Typical Dosage | Research dosing is highly variable due to extreme potency. Typical range: 10-40mg orally or sublingually. Start with lowest doses due to potency. | Topical: Applied as serum or cream 1-2 times daily. Injectable: 1-2mg daily for research purposes. Microneedling protocols often use 0.5-1%. |
| Administration | Can be taken orally, sublingually, or intranasally. Extremely potent - careful dosing is essential. Best used cyclically. | Most commonly used topically for skin applications. Can be injected subcutaneously for systemic effects. Often combined with microneedling for enhanced skin penetration. |
| Side Effects | Limited human data. Reported effects include headache, temporary brain fog during adjustment, and potential mood changes. | Topical use is generally well-tolerated. May cause temporary skin irritation or redness in sensitive individuals. Injectable use may cause injection site reactions. |
