A synthetic peptide derived from the immune fragment tuftsin, studied mainly in Russia for anxiolytic and mild cognitive effects.
What it is & how it works
What it is
Selank is a synthetic peptide based on tuftsin, an immune-derived fragment. It’s studied mostly for anxiolytic (anti-anxiety) effects, often alongside Semax.
How it is thought to work
It’s associated with modulation of GABA/serotonin systems and BDNF, the rationale for its reported calming and mild cognitive effects.
The evidence and the caveat
Selank has more human data than many peptides in this encyclopedia — but most of it comes from a single region and hasn’t been replicated in large independent Western trials.
What it's discussed & studied for
- Anxiety / stress modulation
- Cognition and focus discussion
Discussion of a use is not a claim that it works or is approved.
Research status
Has a body of mostly Russian human and animal research; it is used clinically in some regions but is not approved in the US/EU.
Evidence quality
More human data than many peptides here, but most originates from a single region and hasn't been replicated in large Western trials.
Dosing discussion
Intranasal protocols are described in regional clinical use; no Western-approved label exists.
Educational summary of what is discussed in the literature and community — not a dosing recommendation or medical advice.
Safety & harm reduction
Described as well tolerated in the available literature, but that literature is regionally concentrated and not independently confirmed at scale.
Sourcing literacy
Approved/used in some regions; research-market material elsewhere is unverified.
