Semax + Selank

Overview

Pre-mixed blend of Semax (an ACTH(4-10) analog) and Selank (a heptapeptide tuftsin analog), both developed at the Russian Institute of Molecular Genetics. The individual compounds are registered as prescription drugs in Russia (intranasal); neither is FDA- or EMA-approved. The blend itself is NOT clinically validated — no controlled trial has tested Semax and Selank co-administered.

Mechanism of Action

Extrapolated from component-level research (primarily Russian-language): Semax has been reported to upregulate BDNF/NGF expression and modulate monoaminergic tone; Selank has been reported to modulate GABA-A signaling, enkephalin-degrading enzymes, and serotonergic tone. Any additive effect of co-administration has not been studied in controlled trials.

Research Summary

Each component has separate published research, largely in Russian literature, with limited independent Western replication. The blend format is a vendor convention, not a clinically validated protocol.
