What it is studied for
Selank has been studied for anxiety symptoms and changes in nerve signalling. A study of 62 people compared it with medazepam; separate rat experiments measured changes in genes involved in neurotransmission.
What the evidence says
Small human studies and animal research
The small human comparison reported similar anxiety outcomes between groups, but that alone cannot establish broad effectiveness or long-term safety. FDA says important human safety information for Selank acetate is missing.
