NA Semax

Description

NA Semax is an acetylated analogue of Semax, offered here as a lyophilized peptide reagent for in-vitro laboratory work. It sits in our cognitive and neuro category and is one of the more frequently requested research peptides in Canada among labs comparing Semax-family analogues side by side. Every vial ships with third-party analytical backing, so the material you plan an experiment around is the material you actually receive.

Overview

Each vial contains NA Semax as a lyophilized (freeze-dried) powder, produced to a defined specification and sealed for cold storage. Lyophilization is the standard format for short peptides of this type because the dry solid is far more stable in transit and on the shelf than a pre-made solution, and it lets the researcher choose the reconstitution solvent and working concentration that suit the assay. Sizes are 10mg and 50mg, available as a single vial or a box of ten for labs running repeat work or multiple arms of a study. Orders are fulfilled from Canada with nationwide tracked, discreet shipping.

What it is known for

Buyers know NA Semax as the N-acetylated member of the Semax group — the modification is at the N-terminus, which is why researchers select it when comparing analogue behaviour against the unmodified parent peptide. Within our catalogue it is chosen for the documentation trail more than anything else: independent analysis by Janoshik covering HPLC purity and mass spectrometry identity, with the certificate matched to the batch in the box rather than a generic file. For research groups that need traceable material and Canadian domestic shipping without a cross-border customs wait, that combination is the deciding factor.

Key features

• Lyophilized powder format — The dry solid tolerates shipping and cold storage far better than a solution, and it leaves the choice of solvent, volume and working concentration entirely with the researcher.
• Third-party HPLC purity testing — Purity is verified by an independent analytical lab rather than asserted in-house, so an unexpected result in your assay is less likely to trace back to the reagent.
• Mass spectrometry identity confirmation — Confirms the material in the vial is the compound named on the label — the check that matters most when running analogues from the same family alongside each other.
• Batch-matched certificate of analysis — The COA corresponds to your specific batch, which is what a lab notebook, an internal QA review or a published methods section actually needs.
• 10mg and 50mg vial sizes — Lets a group trial the compound at small scale before committing, then scale up without changing supplier or batch source mid-project.
• Boxes of ten — Keeps a longer study on consistent material and reduces the number of separate orders and reconciliations across a project.
• Cold storage and Canadian domestic dispatch — Shipments stay within Canada with tracking, avoiding customs holds and the temperature uncertainty of a long international transit.
• Sealed single-use vials — Each vial is opened only when needed, limiting moisture ingress and cross-contamination risk across a series of experiments.

Benefits

• You know what you received, at what purity, for that specific batch — not an average from a previous production run.
• Reconstitution stays under your control, so the peptide fits your protocol rather than the protocol bending around a fixed pre-made concentration.
• Domestic tracked shipping shortens the gap between ordering and bench work and removes border delays from the schedule.
• Vial and box options let procurement match spend to the stage of the project, from pilot work through to a full study series.
• Documentation is ready if your institution requires reagent traceability for internal review or grant reporting.

Specifications

Typical applications

• In-vitro laboratory research within cognitive and neuro-focused study programs
• Comparative work against other peptides in the Semax family
• Analytical method development and reference work requiring a characterized peptide
• Preparation of stock solutions at researcher-defined concentrations for downstream assays

Important information

• Research use only. This product is not a drug, supplement, food or cosmetic, is not intended to diagnose, treat, cure or prevent any disease, and is not for human or veterinary use, ingestion or administration.
• Reconstitute with a solvent appropriate to your protocol and handle under conditions suited to peptide work.
• Keep vials cold and sealed until use; minimize repeated temperature cycling of both the dry powder and any reconstituted solution.
• Request the batch-matched COA if your institution requires reagent documentation on file before the material is used.
• Confirm the size and quantity you need before ordering — 10mg and 50mg vials are supplied singly or in boxes of ten.

Common questions

What is the difference between NA Semax and Semax?

NA Semax is the N-acetylated form — an acetyl group is added at the N-terminus of the peptide. Researchers typically stock it when the study design calls for comparing a modified analogue against the parent compound.

Is a certificate of analysis included?

A batch-matched COA is available for every vial, covering HPLC purity and mass spectrometry identity from an independent third-party lab. It corresponds to the batch you receive, not a generic sample.

Why is it supplied as a powder rather than a solution?

Lyophilized peptide is more stable in shipping and storage than a pre-mixed liquid, and it lets each lab choose its own solvent and working concentration instead of inheriting someone else’s.

How should it be stored?

Keep the sealed vial in cold storage until you are ready to reconstitute, and handle any prepared solution according to your own laboratory protocol.

Do you ship across Canada?

Yes. Orders are dispatched from Canada with nationwide tracking and discreet packaging, so shipments stay domestic and avoid customs delays.

Can this be used by or on people or animals?

No. It is a laboratory reagent intended for in-vitro research only and is not a drug, supplement or food. It is not for human or veterinary use of any kind.

In summary

NA Semax from Pure Peptides Canada is a lyophilized research reagent backed by independent HPLC and mass spectrometry testing and a batch-matched certificate of analysis, available in 10mg and 50mg vials or boxes of ten and shipped tracked from within Canada. If your work needs a documented, traceable peptide rather than an unverified one, this is the version to order.
