Overview

Semax is a synthetic ACTH(4-10) analogue characterized in research for nootropic and neuroprotective activity, including activation of dopaminergic and serotonergic systems and modulation of BDNF-related signaling. The N-acetylated form is studied for peptide stability within the same framework.

Studies span nootropic, neuroprotection, and neuroinflammation research under structured conditions.

History

Semax was developed from research into short ACTH-fragment analogues lacking corticotropic activity but retaining neurotropic effects.

Research has characterized its cognitive and neuroprotective endpoints; the N-acetyl form shares this lineage.

Key Research Areas

Research into Semax-class peptides focuses on nootropic and neuroprotective models. Frameworks evaluate monoaminergic activation, neurotrophic signaling, and neuroinflammation endpoints under controlled preclinical conditions.

2 of the 4 areas below are addressed directly by a paper cited on this page.

ACTH(4-10)-analogue peptide models

Addressed on this page by Eremin 2005, Medvedeva 2014, Safarova 2002. Each is linked to its source record in the references below, so what was measured — and in what system — can be read rather than taken on trust.

  • Eremin, KO. et al. (2005) — Semax, an ACTH(4-10) analogue with nootropic properties, activates dopaminergic and serotoninergic brain systems in rodents
  • Medvedeva, EV. et al. (2014) — The peptide semax affects the expression of genes related to the immune and vascular systems in rat brain focal ischemia: genome-wide transcriptional analysis

Nootropic and cognitive research

Addressed on this page by Eremin 2005, Safarova 2002. Each is linked to its source record in the references below, so what was measured — and in what system — can be read rather than taken on trust.

  • Eremin, KO. et al. (2005) — Semax, an ACTH(4-10) analogue with nootropic properties, activates dopaminergic and serotoninergic brain systems in rodents
  • Safarova, ER. et al. (2002) — Trophic effects of nootropic peptide preparations cerebrolysin and semax on cultured rat pheochromocytoma

Monoaminergic and neurotrophic studies

No paper cited on this page reports on monoaminergic or neurotrophic. This heading marks where N-Acetyl Semax Spray 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.

Neuroinflammation frameworks

No paper cited on this page reports on neuroinflammation. This heading marks where N-Acetyl Semax Spray 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 2002 and 2014 — 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 Semax Spray, 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.

Also called

N-Acetyl Semax Spray is also referred to as NA-semax, acetyl semax, and technically as N-Acetyl Semax (Semax analogue).

Preclinical only

N-Acetyl Semax Spray is commonly described online in connection with sharper focus, better memory and improved mood. In the research literature the same compound is filed under ACTH(4-10)-analogue peptide models, nootropic and cognitive research and monoaminergic and neurotrophic studies.

The 3 papers cited on this page, published between 2002 and 2014 (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.

Verification for N-Acetyl Semax Spray is per lot, not per product. The current 10mg lot NASA-CA-26F-10 returned 99.303% purity, 11.58 mg measured, 115.8% of the labelled 10 mg, assayed by Janoshik. Those figures are the laboratory's, published in full rather than reduced to a badge.

The lot code printed on the vial matches the code on the certificate for N-Acetyl Semax Spray. Matching the two is what confirms the unit in hand came from the batch that was tested — a certificate not tied to a lot code proves nothing about any particular unit.

Researchers who buy N-Acetyl Semax Spray in Canada through Eppix Labs receive the lot described by the certificate above: the code printed on the vial label is the code on the certificate, and both are searchable on the batch verification page.

Storage

Reconstitution
Not applicable — supplied in solution
Format
Pre-mixed solution

N-Acetyl Semax Spray ships as a prepared solution rather than as lyophilized powder, so it is already past the point at which a powder would be reconstituted. That shortens handling but tightens storage: a compound in solution is less stable than the same compound dry, and refrigeration from arrival onward is the relevant control.

The stability window for a solution is shorter than the shelf life of a sealed lyophilized vial of the same compound. Records for laboratory work in this format should note the date the unit was opened, not only the date it was received.

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.

Included
  • 1 × sealed spray unit (10mL - 100 mcg per spray / Single Vial), batch-labelled
  • The batch-linked Certificate of Analysis for the exact lot shipped
  • Discreet outer packaging with no product names on the exterior
  • Canada Post Xpresspost, tracked, typically 1–2 business days from Canadian stock
Not included
  • Laboratory consumables of any kind
  • Dosing, administration or protocol guidance of any kind

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 semax. 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.
