How does Selank work?
Synthetic analog of tuftsin (an immunomodulatory peptide). Binds GABA-A receptors indirectly through neurotrophic factor BDNF modulation, producing anxiolytic effect without GABAergic sedation or dependence. In plain terms, Selank is russian-origin synthetic peptide. Anxiolytic and cognitive support without the sedation profile of benzos. Mechanistic detail like this comes largely from preclinical and early research, the human picture is limited.
What people use it for
- Users with situational anxiety or cognitive load
- People wanting focus support without stimulants
- Anyone tapering off anxiolytics under provider guidance
