| Attribute | Dihexa | Noopept |
|---|---|---|
| Category | Nootropics | Nootropics |
| Research Stage | Preclinical | Preclinical |
| Mechanism of Action | Dihexa binds to the hepatocyte growth factor (HGF) receptor c-Met and potentiates HGF signaling. This drives synaptogenesis — the formation of new synaptic connections — in the hippocampus and prefrontal cortex. HGF/c-Met signaling promotes dendritic spine… | Noopept's mechanism of action is multifaceted and — despite decades of research — incompletely understood. Several convergent pathways have been proposed, each supported by preclinical data but none definitively established as the primary driver of its… |

| Administration | Oral, Intranasal, Subcutaneous | — |
| Side Effects | Very potent — risk of excessive cognitive enhancement leading to anxiety, insomnia. Headache at higher doses. Very limited human safety data. Potential for unknown long-term effects. | Noopept is generally well tolerated in the Russian clinical literature, with side effects that are typically mild and transient. However, "well tolerated in Russian open-label trials" is a weaker safety claim than the rigorous multi-phase trial data underlying… |
