Why people look it up
Selank is discussed for anxiety and mental clarity after small human studies and brain-related laboratory work.
Anxiety symptomsLIMITED HUMAN EVIDENCE
A small 62-person comparison reported anxiety-related outcomes; evidence remains limited. Read source ↗
Brain-network effectsLIMITED HUMAN EVIDENCE
A small imaging study examined connectivity, not proven clinical improvement. Read source ↗
Everyday focus or cognitionINSUFFICIENT EVIDENCE
The anxiety comparisons do not establish cognitive enhancement in healthy people. Read source ↗

Evidence, sources & vial math
What the research actually showsHuman studies, evidence limits and mechanisms
What has actually been studied?
Small comparative studies in people with anxiety-related disorders reported signals, but they are not large, independently replicated trials of this vial. Cognitive and performance claims are less established.
Evidence limits: Human reports use differing formulations and routes; an independently checked regimen for this vial and broad clinical benefit are not established.
Product status: Research-vial listings are not FDA-approved medicines. Approved-use labels on this page refer only to the named finished prescription product.
Human research
Selank compared with phenazepam in anxiety-related disorders 2014
What was found: Authors reported anxiolytic and mild nootropic signals with Selank.
Main limit: No placebo arm or independently extractable amount in the accessible abstract; the record cannot establish a regimen or benefit for this dry vial.

Study and prescription-product amounts describe those sources. They do not select an amount for an online research vial.
How researchers think it might work
Selank has been studied for possible effects on brain signaling related to anxiety. The exact mechanism in people remains uncertain.
Show scientific explanation
A rat experiment found changes in expression of genes involved in GABAergic neurotransmission after Selank exposure. This supports a mechanistic hypothesis, not a confirmed human receptor mechanism or broad clinical benefit. Read supporting source ↗

Vial & syringe math
Change the vial total and final liquid volume to see what each U-100 syringe mark represents.
The starting 1 mL is a math example. Enter your final mixed volume to update the numbers.
100 U-100 syringe units = 1 mL. These results assume the labeled amount is evenly mixed through the final liquid volume.
