✱ Overview
What is Semax?
Semax is a synthetic peptide based on a fragment of adrenocorticotropic hormone (ACTH 4–10), modified to resist breakdown. It lacks the hormonal activity of full ACTH.
It has been studied in Russia in stroke recovery and other neurological contexts. Rigorous international trials are limited.
✱ Mechanism
How it works
Animal studies indicate Semax may increase expression of BDNF and its receptor TrkB, molecules that support neuron survival and synaptic plasticity.
Effects on dopaminergic and serotonergic signaling have also been described in rodents. Human mechanistic data are sparse.
✱ Key research areas
What the science says — and how sure it is.
01
Neuronal signaling
Experimental hypothesis
Rodent studies describe effects on dopamine and serotonin systems.
02
Neurotrophic pathways & neuroplasticity
Experimental hypothesis
Rodent studies show increased BDNF/TrkB expression and changes in synaptic gene expression.
03
Experimental neurological applications
Experimental hypothesis
Small clinical studies in stroke from Russia; not independently confirmed.
04
Cognitive research
Experimental hypothesis
No reliable evidence of cognitive enhancement in healthy humans.
