About Dihexa
HGF/MET receptor potentiator; promotes new synapse formation; estimated 7 orders of magnitude more potent than BDNF in synaptogenesis models
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.

Selank
No established clinical contraindications. This is an investigational compound with limited human data and has not been evaluated by the FDA for safety in this context. Consult a qualified clinician.
Selank
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.
