About Dalargin
Binds delta and mu opioid receptors with peripheral preference due to limited CNS penetration. Reduces gastric acid secretion, promotes mucosal blood flow, and inhibits ulcer formation via prostaglandin-mediated pathways.
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.

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.
