Description
PE-22-28 is a synthetic peptide supplied as a lyophilized powder for laboratory research use only. It sits in the cognitive and neuroscience side of the catalogue, where it is used by investigators designing in-vitro work rather than by anyone looking for a finished product. If you are sourcing research peptides in Canada and need documentation you can file with your results, this listing ships from within the country with analytical paperwork tied to the specific batch in your vial.
Overview
Each unit is a single sealed vial containing 10 mg of PE-22-28 as a lyophilized powder, also available in a box of ten vials for laboratories running longer or repeated protocols. The lyophilized format is what keeps a short peptide stable in transit and in storage; the material is reconstituted by the end user in a solvent appropriate to the intended assay, so you control concentration and vehicle rather than inheriting someone else’s. Vials are held cold before dispatch and shipped from Canada with tracking, packaged discreetly and without external branding that identifies the contents.
What it is known for
Buyers know this listing for its documentation. Rather than relying on an in-house claim of purity, every batch goes to Janoshik, an independent analytical laboratory, for HPLC purity testing and mass spectrometry identity confirmation. The certificate of analysis you receive is matched to the batch in your hands, not a generic sample report reused across production runs — which is the difference between a number you can cite in a methods section and a number you have to take on faith.
Key features
- Third-party HPLC purity testing — Purity is quantified by an independent lab, so the figure behind your reagent has not been generated by the party selling it.
- Mass spectrometry identity confirmation — Confirms the material is the peptide named on the label, which rules out the substitution and mislabelling problems that make unsourced research chemicals unusable.
- Batch-matched certificate of analysis — The paperwork corresponds to your specific vial, so results can be traced back to a documented lot if you need to defend or repeat them.
- Lyophilized powder format — Freeze-dried peptide is far more stable in storage and shipping than a solution, and it lets you choose the reconstitution solvent and concentration your protocol calls for.
- 10 mg single vial or box of ten — Run a pilot experiment without committing to bulk, or secure ten vials from the same production run when consistency across a longer study matters.
- Cold storage before dispatch — The material is not left sitting at ambient temperature in a warehouse before it reaches you.
- Domestic shipping from Canada, tracked — No customs holds, no border delays and no uncertainty about how long a temperature-sensitive vial has been in transit.
- Discreet, unbranded packaging — Deliveries to shared labs, campus mailrooms or residential addresses arrive without advertising their contents.
Benefits
- Analytical documentation you can reference directly in research records, rather than a supplier’s unverified claim
- Confidence that the compound in the vial matches the compound on the label
- Control over solvent and working concentration, because the peptide is supplied dry
- Predictable domestic delivery timelines with tracking from dispatch to door
- The option to buy a matched set of vials from one batch when experimental consistency is the priority

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.
- Keep the vial sealed and cold until use, and protect it from light and moisture. Lyophilized peptide is stable in this state; once reconstituted it should be handled as a short-lived preparation.
- Reconstitute with a solvent appropriate to your assay. Solvent choice and working concentration are the researcher’s responsibility.
- Request or download the batch-matched certificate of analysis and confirm the lot number matches the vial before you begin work.
- Buying the box of ten is the reliable way to secure vials from a single batch; separate orders placed over time may draw from different production runs.
Common questions
What form does PE-22-28 arrive in?
A sealed vial containing 10 mg of lyophilized powder. It is not pre-mixed and requires reconstitution in a solvent suited to your protocol.
Who performs the testing?
Janoshik, an independent third-party analytical laboratory. They run HPLC for purity and mass spectrometry for identity confirmation on each batch.
Is the certificate of analysis specific to my vial?
Yes. The COA is matched to the batch your vial comes from, rather than being a single historical report reused across all stock.
Where does it ship from?
From within Canada, cold-stored before dispatch and tracked nationwide, in packaging that does not identify the contents externally.
Can I order more than one vial from the same batch?
The box of ten is supplied together, which is the practical way to keep material consistent across a longer study.
Can this be used in humans or animals?
No. It is sold strictly as an in-vitro laboratory reagent and is not a drug, supplement or veterinary product. It must not be ingested or administered.
In summary
PE-22-28 supplied as a 10 mg lyophilized vial, independently tested by HPLC and mass spectrometry, with batch-matched analytical documentation and tracked domestic shipping. Available as a single vial or a box of ten for work that needs consistency across a run. Strictly for in-vitro laboratory research.
