10mg lyophilized vial
01 · Overview
Selank is a synthetic heptapeptide built on tuftsin, a naturally occurring immune-system peptide, developed at the same Moscow institute that produced Semax. Where Semax lifts and sharpens, Selank settles and steadies — it modulates GABA and serotonin signaling to take the edge off anxiety without the sedation, fog, or dependence that come with benzodiazepines.
It's approved in Russia for anxiety and neurasthenia and is one of the most commonly paired peptides in nootropic protocols: Semax for drive, Selank for calm. Most users take it intranasally for fast CNS delivery.
02 · Fit
People whose 'brain fog' is really anxiety — a loud stress baseline that eats focus, sleep quality, and patience.
03 · Mechanism
Selank is a synthetic analog of the immunomodulatory peptide tuftsin. It modulates GABAergic and serotonergic tone, reduces anxiety-related signaling, and supports stable mood without sedation or dependence.
04 · Use cases
05 · Protocols
Reference protocols paraphrased from published research and common clinical practice. Individual response varies. Work with a qualified provider before running anything below.
Daily anxiety support
Protocol
250–500mcg intranasal once daily
Duration
2–4 weeks on, 1–2 weeks off
Notes
Cycling keeps the response crisp; effects are subtle but build over the first week.
Acute stressful period
Protocol
500mcg twice daily (morning and early afternoon)
Duration
Up to 2 weeks
Notes
Avoid dosing late in the evening if you notice any sleep disruption.
Baseline reconstitution
Reconstitute with 2ml BAC water for 5mg/ml intranasal dropper preparation.
06 · Combinations
The classic pairing is Selank + Semax — calm plus focus. Also stacks well with NAD+ for baseline energy. If anxiety is disrupting sleep, some users pair it with magnesium glycinate and a hard caffeine cutoff instead of adding more peptides.
07 · Safety
08 · Trivia
09 · FAQ
Semax for low drive, brain fog, and flat motivation. Selank for high anxiety, stress reactivity, and a nervous system that won't settle. Many people use both.
It shouldn't. Unlike benzodiazepines it reduces anxiety signaling without sedation — most users describe it as 'the volume knob on stress turning down.'
Some feel a subtle settling within an hour of the first dose; the fuller effect builds over 5–7 days of consistent use.
