N-Acetyl Selank is an N-acetylated form of Selank, a synthetic heptapeptide analogue of the immunomodulatory peptide tuftsin, studied in research for anxiolytic and neuromodulatory signaling.
Experimental models examine its peptidergic activity under controlled laboratory conditions.
Third-party tested for purity, ID, quantity.
Selank is a synthetic tuftsin analogue characterized in research for anxiolytic and neuromodulatory activity, including effects on GABAergic and monoaminergic signaling and on neurotrophic-factor expression. The N-acetylated form is studied for its peptide stability profile within the same research framework.
Studies span anxiolytic-model and neuroprotection research under structured conditions.
Selank was developed from research into stable analogues of the endogenous peptide tuftsin with neuromodulatory activity.
Research has characterized its anxiolytic and memory-related endpoints in model systems; the N-acetyl form shares this lineage.
Research into Selank-class peptides focuses on anxiolytic and neuromodulatory models. Frameworks evaluate peptidergic signaling, anxiolysis, and neurotrophic endpoints under controlled preclinical conditions.

Neuromodulation frameworks
No paper cited on this page reports on neuromodulation. This heading marks where N-Acetyl Selank is discussed in the category rather than a question the cited literature answers, and it is worth knowing which of these areas has work behind it and which does not.
The references section of this page cites 3 primary papers published between 2018 and 2022 — a thin record. Every citation is linked to its PubMed or DOI record so it can be read rather than taken on trust, and the summaries above describe what those papers report rather than what the compound is claimed to do.
Research compounds attract claims that outrun their evidence. Below are the ones most often encountered for N-Acetyl Selank, set against what the papers cited on this page actually report. Where the record is thin or contested, that is stated rather than smoothed over.
N-Acetyl Selank is also referred to as NA-selank, acetyl selank, and technically as N-Acetyl Selank (Selank analogue).
N-Acetyl Selank is commonly described online in connection with sharper focus, better memory and improved mood. In the research literature the same compound is filed under tuftsin-analogue peptide models, anxiolytic-signaling research and neurotrophic and memory studies.
The 3 papers cited on this page, published between 2018 and 2022 (2 in animal models) describe laboratory and animal work. None reports a controlled trial in humans. Findings in cell culture or in a rodent model describe what happened in that system; they do not establish that the same occurs in humans, and this compound is not approved for human use.
Nothing above is a statement of what this material does. It is a summary of what has been published and what has not. Eppix Labs supplies research materials only and provides no dosing, administration or protocol guidance.
Every lot of N-Acetyl Selank is independently assayed before it is released, and the certificate for the lot shipped is published rather than summarised. Where a certificate for a current lot is not yet posted, the lot has not yet been released against it.
Researchers who buy N-Acetyl Selank in the United States through Eppix Labs receive a batch-labelled vial whose certificate is published against that lot code, so the material can be matched to its analysis rather than to a generic specification.
- Lyophilized storage
- −20 °C long-term; stable at room temperature in transit
- After reconstitution
- 2–8 °C
- Light
- Protect from UV and direct light
- Freeze-thaw
- Avoid repeated cycles
- Vehicle
- Bacteriostatic water in most published protocols
- Format
- Lyophilized powder
N-Acetyl Selank is supplied as lyophilized powder. In the dry state the material is comparatively stable, which is why it ships at ambient temperature without a cold chain; once reconstituted it is a peptide in solution and the handling constraints tighten considerably. At 7 residues it is short enough to be produced by solid-phase synthesis, and the published sequence on this page is what an identity assay is checked against.
Repeated freeze-thaw cycling is the handling error most likely to degrade material of this class, because each cycle concentrates solutes at the ice boundary. Where a protocol calls for the same vial across multiple sessions, the published literature generally describes aliquoting after reconstitution rather than re-freezing the whole volume.
Vials may appear empty on arrival. Lyophilized material collects at the base of the vial and is often not visible until the vial is inspected under direct light.
- 1 × sealed glass vial in the strength selected (10mg / Single Vial, 10mg / 5-Pack, 10mg / 10-Pack available), batch-labelled
- Batch documentation for the lot shipped, once its certificate is published
- Discreet outer packaging with no product names on the exterior
- FedEx, tracked, typically 1–3 business days domestically
- Bacteriostatic water or any other reconstitution vehicle
- Syringes, needles or filters
- Dosing, administration or protocol guidance of any kind
Reconstitution materials are sourced separately. The reconstitution calculator on this site works out concentrations for a given volume, but it is an arithmetic tool for laboratory record-keeping and not a protocol.
No. Eppix Labs products are supplied exclusively for laboratory research. We do not provide dosing, administration, or usage guidance.
Each unit contains the labeled quantity of n acetyl selank. Independent third-party analysis verifies purity, identity, and net content per batch.
The unit contains only the research compound. Any laboratory materials required for reconstitution or experimental procedures must be sourced separately.
Duration depends entirely on research design, storage conditions, and laboratory protocol.
