Model

Systematic review (PubMed, Embase and Cochrane CENTRAL from inception through March 2026, following PRISMA) of studies of GHK-Cu as a standalone intervention

Twenty studies were included: 18 preclinical studies and 2 randomized controlled trials. The authors synthesize preclinical data on extracellular matrix synthesis (matrix proteins and glycosaminoglycans), metalloproteinase activity, cell proliferation, inflammatory markers and delivery systems. Their conclusions about the two human trials are not summarized in this profile, and not every included study is listed here.

Systematic review of 36 studies (35 preclinical, 1 in humans): mechanism, musculoskeletal endpoints, biotransformation and safety

Model

Systematic review (PubMed, Cochrane, Embase; through June 2024) of studies on mechanism, musculoskeletal outcomes, biotransformation and safety

Of 544 records identified, 36 studies were included (35 preclinical and 1 in humans). The authors synthesize functional, structural and biomechanical measures from preclinical musculoskeletal models, together with GHR expression and inflammatory cytokine levels; the only study in humans was retrospective. No human safety data were found, and the evidence was graded as level IV and V.

Critical narrative review of preclinical studies in rodent muscle and connective-tissue models

Critical narrative review of preclinical studies in rodent muscle and connective-tissue models

Critical review by an independent group (Loughborough University) of the preclinical literature in small rodent models of muscle and connective-tissue lesions. It notes that only a handful of research groups had studied the peptide in depth, that the effects reported in rodents had yet to be confirmed in humans and that the precise mechanisms still needed to be understood.

Narrative review of gene-expression (Connectivity Map) data on GHK and earlier preclinical studies

“Regenerative and Protective Actions of the GHK-Cu Peptide in the Light of the New Gene Data”

Model

Narrative review focused on gene-profiling data (Connectivity Map) and earlier preclinical studies

Narrative review that compiles the available gene-expression data for GHK and relates them to actions described in skin, pulmonary connective tissue, bone, liver and gastric mucosa in experimental models, as well as antioxidant effects, effects on inflammatory markers and effects on the proteasome system. The authors interpret the gene data as a possible explanation for the diversity of effects; most of the proposed pathways have not been validated in controlled human studies.

Narrative review of in vitro, animal and gene-expression data on GHK by company-affiliated authors

Model

Narrative review of in vitro and animal studies, observations in humans and gene-expression data

Narrative review proposing a role for GHK, as a copper complex, in tissue remodeling through effects on the synthesis and breakdown of glycosaminoglycans, metalloproteinases and their inhibitors, decorin, and the attraction of immune and endothelial cells; it also summarizes animal lesion models and observations in humans. It states that, according to database analyses, GHK changes the expression of thousands of human genes. The authors declare an affiliation with a company that sells GHK-Cu products.

Narrative review by the originating group: the BPC 157 fragment and its early rat lesion models

Narrative review by the originating group of its own preclinical work

Early overview by the originating group of its own work. It refers back to the group's isolation of a gastric juice peptide (BPC, Mr about 40,000), presents the fully characterized 15-amino-acid fragment BPC 157, which the authors consider essential for the activity they studied, and sets out their hypothesis that the stomach mediates responses to stress in other organs. It summarizes the group's lesion models in several organs and proposes the peptide as a possible endogenous mediator.
