What it is and how it works
GHK-Cu is a copper complex of the tripeptide glycine-histidine-lysine. In the cited fibroblast-culture experiment it stimulated collagen synthesis. Cells growing in a laboratory are useful for studying mechanisms, but do not reproduce an entire person’s skin or response to an injected product.

Laboratory study
This label describes the selected source below. It is not a complete ranking of the literature, a safety score, or an approval status.
- Study or assessment
- Maquart et al., 1988 — GHK-Cu and fibroblast collagen synthesis
- Design
- Cell-culture experiment.
- Who or what was studied
- Cultured fibroblasts; not a trial in people.
- What was observed
- The copper-peptide complex increased collagen synthesis under the experimental conditions.
- Limits of interpretation
- This selected study cannot establish an injectable treatment’s safety or demonstrate a visible cosmetic benefit in people. It does not summarize the entire topical literature.
What the evidence means
Evidence must match the formulation and route; a cosmetic claim cannot validate an injectable product.
Approval and regulatory context
An injectable research product should not be confused with an approved medicine or a topical cosmetic.
Safety and uncertainty
Injectable human safety data are limited.
What remains uncertain
A topical formulation, a laboratory reagent, and an injectable product answer different questions. Product-specific studies would be needed to connect a mechanism with a reliable clinical outcome for a given route.
These summaries are introductory and are not a complete account of the literature, adverse effects, contraindications, or interactions. Absence of a listed risk does not mean absence of risk. Different compounds, formulations, and routes cannot be treated as interchangeable.
