Dihexa

Editorial context from existing sources; independent scientific review pending. Numerical findings held. A reported-use topic does not establish direct evidence for that aim.

Dihexa is an experimental peptidomimetic studied in laboratory and animal models. A key 2014 HGF/c-Met mechanism paper was retracted in 2025; the separate 2013 discovery study carries a 2021 notice of concern. Other animal studies report model-dependent findings, including benefits in some memory tasks and a negative result in a rat model of Huntington-like disease. Additional preclinical work supports investigation of HGF/MET involvement, but the sources reviewed do not establish cognitive benefit, safety, or a validated dosing regimen in people. Laboratory potency comparisons must not be presented as proof of clinical superiority over BDNF. Scientific/expert review pending.

Claims that relied on that paper need independent confirmation. The retraction does not establish that every possible claim about Dihexa is false, and it does not supply human efficacy or safety evidence either.

Sources and proposed-mechanism explanation

The proposed mechanism attracted interest, but a plausible pathway depends on reliable supporting experiments.
