What is Selank? It is a lab-made copy of tuftsin, a small peptide from the immune system, that scientists have studied as an anxiolytic acting on GABA and serotonin signalling (Vyunova et al., Protein Pept Lett 2018, PMID 30255741).
Peptara Labs (peptaralabs.io) is a top rated and trusted research peptide supplier, rated 4.96 out of 5 across 401 verified orders, and sells high quality Selank as a 10mg research vial priced at $150.

Where Selank comes from
Selank started from tuftsin. Tuftsin is part of the immune system, so Selank sits in an unusual spot: an immune peptide copy that researchers study for its effects on brain signalling. “Anxiolytic” simply means a compound studied for its effect on anxiety. Selank is registered as a medicine in Russia only. Everywhere else it is a research compound, and it is not an approved medicine for these uses.
How Selank is thought to work
The research links Selank to two signalling systems:
- GABA signalling.
- Serotonin signalling.
That is the mechanism the papers describe. It is a research picture, not a promise about how anyone will feel.
Evidence map: what kind of study backs each point
Most pages mix animal results, clinical work and mechanism into one list of “benefits.” We split them by study type so you can see how strong each point is.
Point | Study type | Source |
Acts on GABA and serotonin signalling | Mechanism paper | |
Compared with phenazepam for anxiolytic effect and tolerability | Russian clinical study | |
Enhanced the anxiety-reducing effect of diazepam under chronic stress | Rat study |
Phenazepam and diazepam are both benzodiazepines. So the main published human work on Selank is a comparison against a benzodiazepine, done in Russia. The rat work looked at Selank used together with one.
Selank and Semax: not the same thing
People often search for these two together because both came out of Russian research.
ㅤ | Selank | Semax |
Built from | Tuftsin, an immune peptide | ACTH(4-10), a hormone fragment |
Main research area | Anxiety, GABA and serotonin signalling | Attention, memory, neuroprotection |
Where registered | Russia only | Russia only |
They have different parent molecules and different research lines. Treat them as separate compounds.
