Description
Semax is a short synthetic peptide sold here as a laboratory reagent, not a consumer product. It sits in our Cognitive & Neuro category and is bought by investigators running neuropeptide and ACTH-fragment work in cell and tissue models. If you are sourcing research peptides in Canada and need documentation that matches the vial in front of you rather than a generic PDF, that is the difference this listing is built around.
Overview
Semax is a heptapeptide based on the ACTH(4-10) fragment sequence Met-Glu-His-Phe-Pro-Gly-Pro, with the terminal Pro-Gly-Pro extension that distinguishes it from the parent fragment. It is supplied as a lyophilized powder in a sealed 10 mg vial, either singly or in a box of ten for laboratories running larger series or repeat assays. The material arrives dry and requires reconstitution in a suitable research solvent chosen by the investigator for the assay in question. Every lot is submitted to Janoshik, an independent analytical laboratory, for reversed-phase HPLC purity and mass spectrometry identity confirmation, and the resulting certificate of analysis is matched to the batch you receive. Orders ship cold and discreetly from within Canada with nationwide tracking.
What it is known for
Buyers know Semax as one of the standard reference peptides in ACTH-fragment and neuropeptide research, and they choose this listing for the paperwork rather than the promise: independent HPLC and MS testing through a recognised third-party lab, a certificate tied to the specific batch, and a domestic Canadian supply chain that avoids customs delays and long transit at ambient temperature.
Key features
- Lyophilized 10 mg vial — Dry powder is the most stable form to ship and store, and it lets you set your own concentration and solvent instead of inheriting someone else’s formulation.
- Third-party HPLC purity testing (Janoshik) — Purity is verified by a lab with no commercial stake in the result, so your assay variability is less likely to trace back to the reagent.
- Mass spectrometry identity confirmation — Confirms the molecular mass corresponds to the intended heptapeptide — the check that separates the correct sequence from a mislabelled or degraded one.
- Batch-matched certificate of analysis — The document reflects the lot in your hand, which is what a supervisor, grant record or method section actually requires.
- Box-of-ten option — Lets a lab secure multiple vials from a single lot, removing batch-to-batch variation as a variable across a longer study.
- Cold storage and cold-chain dispatch — Peptide integrity depends on temperature history before it ever reaches your bench, not just after.
- Shipped domestically from Canada — No international border crossing means shorter transit, tracked delivery nationwide and less time in uncontrolled conditions.
- Sealed single-use format — Reduces the handling and moisture exposure that shorten the working life of a reconstituted peptide.
Benefits
- Documentation you can cite — independent purity and identity data tied to your specific batch
- Fewer confounded results, because reagent quality has been characterised before you start
- Flexibility to reconstitute at the concentration and in the solvent your protocol calls for
- Shorter, tracked domestic shipping instead of extended international transit
- The option to buy a full lot at once when experimental consistency matters

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.
- Store the sealed lyophilized vial cold. Keep it dry and protected from light until you are ready to use it.
- Reconstitute with a solvent appropriate to your assay, added gently down the vial wall rather than directly onto the powder. Avoid vigorous shaking.
- Once reconstituted, keep the solution cold and minimise freeze-thaw cycles; aliquot if the material will be drawn on repeatedly.
- Request or download the batch-matched certificate of analysis and confirm the lot number matches the label before you begin.
- Handle in a suitable laboratory setting with appropriate PPE. Purchase is intended for qualified research buyers.
Common questions
What exactly am I receiving?
A sealed vial containing 10 mg of Semax as a lyophilized powder, or a box of ten such vials. No solvent, syringe or reconstitution kit is included — you supply the solvent appropriate to your protocol.
Who performs the testing?
Janoshik, an independent third-party analytical laboratory. They run reversed-phase HPLC for purity and mass spectrometry for identity, and the resulting certificate is matched to the batch shipped to you.
Can I get the certificate of analysis for my specific batch?
Yes. The COA is batch-matched, so you can verify that the lot number on the document corresponds to the number on the vial.
How should I store it before use?
Keep the unopened vial cold, dry and away from light. The lyophilized form is the most stable state, so leave it dry until the day you need it.
Is this the same as a pharmaceutical or supplement product?
No. It is a laboratory research reagent supplied for in-vitro work. It is not a drug, supplement, food or cosmetic and is not for human or veterinary use.
Why buy the box of ten?
Ten vials from one lot means one purity and identity profile across your whole series, which removes batch variation as a source of noise in longer or repeated experiments.
In summary
A characterised Semax reagent with independent HPLC and MS data behind it, a certificate that matches your batch, and cold, tracked shipping from within Canada. Single vial for a short experiment, box of ten when you need one lot to carry a full study. Research use only.
Daniel Wright –
Helps tremendously with ADHD symptoms and regulating the nervous system. I’m able to relax and even have much better short term memory function. I had no idea people developed their own way of being around me before, i.e telling me 5x to do something and then not remembering either time, and because they’ve developed this system but now I have my focus, cognitive function and memory back its actually super annoying for me but also clear as day I could not rely on my brain, and neither could anyone else.
Ps. My time management has also drastically improved. Almost never late now, imagine that!
