About Davunetide
Stabilizes microtubules by interacting with tubulin and microtubule-associated proteins. Activates SIRT1, reduces amyloid-β toxicity, and enhances synaptic plasticity. Protects against tau hyperphosphorylation.
About Selank
Selank is believed to modulate the expression of GABA-A receptor subunits and increase BDNF levels, contributing to its anxiolytic and neuroprotective profile. It appears to regulate serotonin transporter gene expression and influence dopaminergic signalling. Unlike classical anxiolytics, it does not appear to produce tolerance or physical dependence in animal models.

Semax
Research suggests Semax and Selank may produce complementary cognitive and stress-modulating effects when combined. Semax is studied for BDNF upregulation and cognitive enhancement, while Selank is studied for anxiolytic and immune-regulatory activity — distinct mechanisms with potential overlap in neuroprotective signaling.
