As of September 2026, the FDA and the EMA have not approved Selank. The record says it is registered and sold as a drug only in Russia and some CIS countries. The supporting trials are in Russian and have not been independently repeated to Western standards. A vial sold as Selank outside those countries is a separate question, and you cannot check its contents by looking at it.

What is Selank?
Selank is a lab-made chain of seven amino acids, modeled on tuftsin, a natural immune-signalling peptide. The Institute of Molecular Genetics of the Russian Academy of Sciences developed it as an anti-anxiety compound. The record says it is sold in Russian and Ukrainian pharmacies, and that nootropic communities in other countries use it for anxiety and focus.
Does Selank work?
One small Russian trial reported fewer anxiety symptoms. Whether that holds up, nobody knows: no large randomized trial has been independently repeated and peer-reviewed in English.
What we found. 1 completed randomized trial counted on the record. 1 lab-dish study of gene activity.
| Study | Tested in | Status | What it shows |
|---|---|---|---|
| Selank in generalized anxiety disorders and neurasthenia | People | Published. A Russian trial with an English abstract | Reported fewer anxiety symptoms in a small clinical sample |
| Lab study of GABA, Selank and olanzapine | Lab dishes | Published | Changed the activity of one group of genes. The record calls this a proposed mechanism |
A lab-dish study can point to how a compound might act. It cannot show what happens in a person.
How we count a trialIs Selank safe?
The record holds no human safety finding for Selank. It says long-term safety and drug interactions are essentially unknown. The FDA and the EMA have never evaluated it. The human evidence is thin and largely regional. All of that concerns the compound itself. What a seller puts in a vial is a different question, with its own section below.
Is Selank legal?
- United States
- Not approved by the FDA. The record says the FDA has never evaluated it.
- European Union
- No EMA marketing authorisation. The record says the EMA has never evaluated it.
- Elsewhere
- The record says it is registered and sold as a drug only in Russia and some CIS countries. One field names Russian and Ukrainian pharmacies, for anxiety and stress-related conditions.
- Sport
- Not named on WADA's list. That is not clearance.

What is in a vial sold as Selank?
The record says Selank is registered and sold only in Russia and some CIS countries, and that nootropic communities in other countries use it. It does not say how the product reaches them. A "research use only" label guarantees nothing about purity. A certificate of analysis counts only if it names your lot number, a lab with no stake in the result, and the method used. Purity and identity are separate tests.
Three questions to ask the seller:
- Which lot number is this certificate for?
- Who ran the test, and are they independent of you?
- Does the report confirm identity by mass spectrometry, or purity alone?
What don't we know?
- Whether the anxiety finding holds up. Nobody has repeated it independently to Western standards.
- What long-term use does. The record calls long-term safety essentially unknown.
- What it does alongside other medicines. Drug interactions are essentially unknown too.
- What is in any given vial.
The other side
Selank is a registered drug in Russia and some CIS countries. A personal result is real to the person who had it. It cannot separate the compound from the vial, or from a mood already lifting.
What would change this record?
- An independent, peer-reviewed randomized trial run outside Russia, large enough to settle the question.
- A submission to a regulator after that trial.
Three questions to ask next
- What does 'research use only' actually mean?
- How can you tell if a peptide vendor is legitimate?
- How do you read a certificate of analysis?
Ask better questions.
More questions about Selank
Is Selank approved by the FDA?
- No. The FDA has not approved Selank, and the record says the FDA and the EMA have never evaluated it.
Is Selank approved anywhere?
- Only in Russia and some CIS countries, the record says, where it is registered and sold as a drug. One field names Russian and Ukrainian pharmacies. The record holds no official document behind either line.
Has Selank been tested in people?
- Yes, in one small Russian trial on the record. It reported fewer anxiety symptoms and is published with an English abstract. The record says its trials have not been independently repeated to Western standards.
Is Selank the same as Semax?
- No. Selank is modeled on tuftsin and was developed for anxiety. Semax is based on a fragment of ACTH and is approved in Russia for stroke and cognitive uses. The two records name the same Russian institute.
Is Selank banned in sport?
- It is not named on WADA's list. That is not clearance.
