Know your compound
Selank is a synthetic peptide built from tuftsin, a small immune-signaling fragment your body already makes. It's a lab cousin of Semax, both developed in Russian research programs to study calm and cognition.
What caught researchers' attention: in rat studies it eased anxiety markers as well as benzodiazepines — but without the drowsiness or dependence those drugs are known for. That points to a different route through the GABA system, the brain's main "slow down" signaling network.

The research
The published findings behind this compound — the headline numbers, in plain terms, each cited to source. Preclinical results are directional (animal / in-vitro) and shown for context, not as therapeutic claims.
In rodent anxiety models, Selank eased anxiety markers about as well as benzodiazepines — but published animal work reported no sedation or dependence.
Relative depiction; effect not quantified in source.
In a rat chronic-stress model, adding Selank to diazepam calmed the animals more than diazepam given alone.
Directional finding; magnitudes are relative, not measured values.
In human nerve-cell cultures, Selank shifted the activity of several genes tied to GABA signaling — the brain's main 'slow-down' network — hinting at how it may act.

Mechanism
An anxiolytic research peptide studied for calming without the downsides of sedatives.
Studied in rat models for easing anxiety markers as effectively as benzodiazepines.
Investigated for that calming effect without the drowsiness or dependence of sedative drugs.
Researched for effects on gene expression, including BDNF-related signalling.
