What it is
Selank with an acetyl group at the N-terminus, sold as a research chemical.
How it is proposed to work
Marketed as longer-acting through resistance to aminopeptidase cleavage. The chemistry is plausible; the human consequence is uncharacterised.
Approved medical uses
None. N-Acetyl Selank has no approved human medical indication in the jurisdictions we track. Any use is outside an approved label.
Human research
Each entry states what the study found and, separately, what it cannot show.
No adequate published human research. This absence is the reason for the evidence grade above — it is not a gap we can fill with animal data.
Preclinical research
Animal and laboratory work. Useful for generating hypotheses; it cannot establish that something works in people.
No preclinical studies catalogued.
Potential safety concerns
- CautionInsufficient
No clinical data for this variant. Selank's use history does not transfer to a modified molecule.
Known interactions and contraindication considerations
- Uncharacterised.
This list is not exhaustive and is not a substitute for a clinician reviewing your full medication history.
Regulatory status
Status is shown per jurisdiction and is accurate only as of the date stated. Where a compound is approved, the approval is bound to a specific formulation, manufacturer and indication — shown in the detail column.
| Jurisdiction | Standing | Detail |
|---|---|---|
United States FDA | Unapproved / investigational as of 11 Aug 2026 | No marketing authorisation. The FDA has not evaluated this compound — that is an absence of any opinion, not a negative finding. |
European Union EMA | Unapproved / investigational as of 11 Aug 2026 | No marketing authorisation. |
India CDSCO | Unapproved / investigational as of 11 Aug 2026 | Not approved for human use. A first-time synthetically manufactured peptide falls under the new-drug pathway. |
Russian Federation Ministry of Health / Roszdravnadzor | Unapproved / investigational as of 11 Aug 2026 | The registered Russian medicine is Selank. This variant is not that product. |
How it is being used
What the grey community actually runs, the reasoning they give, and our read on whether it follows from known biology. This is observation, not evidence, and not a recommendation.
No community use documented for this compound yet. Absence here means our editorial team has not reviewed and verified a pattern — not that none exists.
Active clinical trials
No registered trials currently tracked for N-Acetyl Selank.
What remains unknown
The questions that would change our assessment if they were answered.
- Does it differ from Selank in any way a person would notice?
