Selank: what it is, what the evidence says, and its real status

Semax's calmer sibling, studied for calm and anxiety.

Can you actually get it?

Plain-English verdict: No availability record.

Regulatory status: No regulatory record.

How does Selank work?

A synthetic analog of the peptide tuftsin, proposed to modulate GABA and anxiety-related pathways.

What it does — and what it does not do

What it does: Researched for calm, anxiety, and stress-resilience support.

What it does not do: It is not an anxiety medication and is not a substitute for mental-health care.

How honest is the evidence?

Evidence grade C — Mixed / early human evidence.

A grade measures how much human evidence exists, not whether a molecule is good, safe, or worth your interest. Read our grading methodology for what each grade means.

What we still don't know: Controlled human evidence is limited; durability of effect is unclear.

WADA status: Not prohibited.

Who should not take it

Not characterized in Western practice; not a substitute for mental-health care.
