Selank is a synthetic peptide studied mainly for anxiety-related and cognitive
endpoints. Its evidence base has a specific characteristic worth understanding
up front.
Chemical identity & structure.
Selank is a synthetic heptapeptide (seven amino acids). It is derived from
tuftsin, a naturally occurring immunomodulatory peptide fragment, with an
added stabilizing sequence that extends its duration of action relative to
tuftsin itself. It was developed by Russian researchers.
Mechanism of action.
The mechanisms reported for Selank should be read as still being characterized.
The literature describes effects on the GABA system (relevant to its reported
anxiolytic profile), modulation of brain-derived neurotrophic factor (BDNF),
effects on the metabolism of enkephalins (endogenous opioid peptides), and
immune-modulating activity inherited from its tuftsin origin. No single
mechanism is established as primary.
Key research findings.
Research reports anxiolytic ("anti-anxiety") effects without the sedation and
dependence associated with conventional benzodiazepines, along with reported
effects on attention and stress resilience.
The research / citation base.
This is the key honest point: the Selank literature is **predominantly from
Russian research groups**, and independent replication outside that body of work
is limited. Selank is used clinically in Russia but is **not approved by the FDA
or EMA**. Western-standard large trials are essentially absent. The mechanism and
efficacy picture should be treated as preliminary.
Human clinical trial data.
A Russian randomized trial (Zozulia et al., 2008) compared Selank with medazepam
in 62 patients with generalized anxiety disorder or neurasthenia
(PubMed); the abstract does not
state administration parameters, so VialTalk lists none.
Quality & sourcing notes.
A defined heptapeptide should carry a batch-specific COA with mass-spectrometry
identity and HPLC purity. Given that much of the literature is hard to
independently verify, sourcing diligence matters.
