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 Semax
Semax is believed to upregulate brain-derived neurotrophic factor (BDNF) and other neuroprotective factors, enhancing neuronal survival and synaptic plasticity. It modulates the dopaminergic and serotonergic systems, contributing to its reported effects on mood and focus. Its mechanism of action differs from classical stimulants — it does not act on adrenergic receptors and does not produce typical stimulant tolerance or dependence patterns.

Davunetide
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.

Semax
Selank
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.
