What is Semax + Selank Blend?

Semax + Selank Blend (Dual neuropeptide stack β€” cognitive activation + anxiolysis) is a Pre-blended Semax + Selank (equimolar per vial). Pre-blended combination of Semax (BDNF/NGF upregulation, monoaminergic activation β€” alerting/cognitive) and Selank (GABA-A modulation, BDNF upregulation, anxiolysis β€” calming). Complementary profiles: cognitive enhancement with anxiolytic co-effect. Shared BDNF upregulation with distinct primary mechanisms.

Research Applications

Complementary Neuropeptide Combination

Activation (Semax) + anxiolysis (Selank) β€” distinct primary mechanisms

Shared BDNF Upregulation

Both compounds increase BDNF via different pathways

Cognitive + Anxiolytic Research

Dual profile research without separate reconstitution

vs Individual Components

Blend vs Semax-alone vs Selank-alone β€” interaction research
