Primary entity: SelankClass: Tuftsin-derived neuropeptide — not FDA-approvedCluster: Nootropic neuropeptides
Selank is a synthetic peptide analog related to tuftsin (commonly described as Thr-Lys-Pro-Arg-Pro-Gly-Pro) discussed for anxiolytic and nootropic research themes. It is not FDA-approved. Forums often pair it with Semax; they are different peptides — see Nootropics hierarchy.
Different sequences, different parent motifs (tuftsin vs ACTH fragment). “Nootropic peptide stack” folklore does not merge their evidence bases.
Not FDA-approved. Russian medicinal contexts exist for Selank products in some non-U.S. contexts; that is not FDA approval. U.S. RUO nasal products are not FDA-approved drugs.
Not covered by HHS's Oct 28, 2026 policy, which names six other peptides. Selank left FDA's Category 2 list in 2024 after a withdrawn nomination; FDA's page raises immunogenicity concerns. Not on the final bulks list. See the compounding status guide.
Key takeaways
- Selank = tuftsin-derived synthetic peptide.
- Not FDA-approved in the U.S.
- Hierarchy: nootropic neuropeptide — not a classic stimulant.
- Distinct from Semax despite frequent stacking talk.
- No dosage charts.

What is Selank?
Selank is a synthetic hexapeptide designed as an analog of the immunomodulatory peptide tuftsin, with additional residues in the common literacy description. It is discussed for anxiolytic / nootropic themes in research and has medicinal history in Russia. Taxonomy: Nootropics hierarchy.
| Chemistry | Tuftsin-derived synthetic peptide |
|---|---|
| U.S. FDA approval | No |
| Folk class | Nootropic / anxiolytic peptide |
| Common comparison | Semax |
Also known as
- Selank — primary name.
- Tuftsin analog — parent-motif literacy.
- Form variants (e.g., N-acetyl narratives in commerce) — identity ≠ dose advice.
Do not equate it with benzodiazepines. Different chemistry, evidence, and regulatory story. Not medical advice.
How is Selank classified?
Nootropic neuropeptide bucket in our hierarchy — peptide neuromodulator class, separate from eugeroics and bromantane-like actoprotectors. Not FDA-approved.
What is Selank not?
| Selank is not… | Why that matters |
|---|---|
| Semax | Different peptide |
| FDA-approved anxiolytic | No U.S. approval |
| A benzodiazepine | Different class entirely |
| Something we dose or source | Refusal |
How is Selank thought to work?
Research discussions involve GABAergic / enkephalin / immune-modulatory themes depending on the paper — often framed as anxiolytic-adjacent neuromodulation without classical benzodiazapine structure. Mechanism literacy ≠ proven safe self-medication.
What human vs animal vs label evidence exists?
| Evidence type | What exists (summary) | Maturity |
|---|---|---|
| Human — Russian clinical contexts | National-use literature of varying quality | Human Context-limited — |
| Animal | Anxiety / cognition models | Animal |
| U.S. label | None | None |
What has Selank been studied for?
Themes include anxiety-related and cognitive research narratives plus Russian clinical use history. Studied abroad ≠ U.S. approved drug.
What safety topics come up?
No U.S. PI. Product quality of gray-market nasal sprays is a first-order issue. Not a substitute for evidence-based anxiety care. Not medical advice.
What is Selank's regulatory status?
- U.S.: Not FDA-approved.
- Russia: Medicinal Selank contexts.
- Sport: Verify WADA relevance by current list.

Frequently asked questions
Is Selank FDA approved?
No.
Is Selank the same as Semax?
No. Different sequences and parent motifs.
Is Selank an anxiety medication in the U.S.?
Not as an FDA-approved drug. Do not use this page as treatment advice.
Where does it sit vs bromantane?
Selank is a peptide; bromantane is a non-peptide actoprotector-like synthetic — see hierarchy.
Why no dosage chart?
YMYL policy.
Selank is not FDA-approved. ≠ Semax. Disclaimer.
