Description
Cortagen is a lyophilized peptide reagent intended strictly for controlled laboratory research. It sits in the anti-aging and cellular category of our research peptides Canada catalogue, and is supplied in a form researchers can reconstitute themselves in the solvent and at the concentration their protocol calls for. It is not a drug, supplement or cosmetic, and it is not for human or veterinary use.
Overview
Each unit is a single 20mg vial of Cortagen presented as a lyophilized powder — a dry, sealed format chosen because it keeps a peptide stable in transit and in cold storage far better than a pre-mixed solution would. The researcher adds a suitable solvent at the point of use, which means the working concentration is set by the experiment rather than by the supplier. Cortagen is also available in a box of ten vials for laboratories running longer studies or repeat assays, where drawing from the same production batch across a series of experiments removes one source of variability. Every batch is analyzed by Janoshik, an independent third-party laboratory, for purity by HPLC and identity by mass spectrometry, and the certificate of analysis you receive is matched to the batch in your hands.
What it is known for
Buyers know Cortagen for the documentation that accompanies it. Independent HPLC and MS testing through Janoshik, with a batch-matched COA rather than a generic reference document, is the difference between a reagent you can cite in a methods section and one you have to take on faith. Combined with domestic dispatch — Canadian-owned, shipped cold and tracked from within Canada rather than held at a border — it removes the two problems researchers most often report with imported peptide reagents: unverifiable identity and unpredictable transit conditions.
Key features
- Lyophilized powder format — Dry peptide is markedly more stable than reconstituted peptide, so the vial survives shipping and cold storage with its integrity intact until you choose to open it.
- Third-party HPLC purity analysis — Purity is measured by an independent lab with no commercial stake in the result, so the figure on your COA is an assessment rather than a marketing claim.
- Mass spectrometry identity confirmation — Confirms the material in the vial is the compound named on the label — the check that separates a verified reagent from an assumption.
- Batch-matched certificate of analysis — The COA corresponds to the specific lot you received, so your records, methods write-up and any internal QA review all trace back to real analytical data.
- 20mg single-vial and ten-vial box options — A single vial suits pilot work and method development; the box of ten lets a longer study run on consistent material and reduces per-vial handling and reordering.
- Cold storage and discreet, tracked Canadian dispatch — Temperature-conscious handling and domestic shipping mean no customs hold and no unexplained gap in the cold chain, and you can see where the parcel is throughout.
- Researcher-controlled reconstitution — You set solvent and concentration to match your protocol instead of working around a fixed pre-mixed dilution.
Benefits
- Analytical documentation you can file, cite and defend during internal review or audit
- Consistent material across a study when ordered as a ten-vial box from one batch
- Shorter, more predictable transit than imported reagents, with tracking from dispatch to delivery
- Full control over solvent choice and working concentration at the bench
- Confidence that identity and purity were assessed by a lab independent of the seller

Typical applications
- In-vitro laboratory research within the anti-aging and cellular research category
- Method development and assay optimization where a documented reagent is required
- Multi-run studies needing consistent material from a single tested batch
- Institutional research programs that require batch-level analytical documentation on file
Important information
- Research use only. Not a drug, supplement, food or cosmetic. Not for human or veterinary use, ingestion or administration, and not intended to diagnose, treat, cure or prevent any disease.
- Keep the vial cold and sealed until you are ready to use it; lyophilized peptide is more stable dry than in solution.
- Reconstitute with a solvent appropriate to your protocol and handle under conditions suited to your laboratory’s procedures.
- Once reconstituted, treat the material as a prepared solution with a shorter working life than the sealed vial — plan the experiment around when you open it.
- Request or download the certificate of analysis for your specific batch and keep it with your records.
- Check that the size you order matches your study design; buying a ten-vial box in one order is the reliable way to keep a batch consistent across runs.
Common questions
What form does Cortagen arrive in?
As a lyophilized powder in a sealed vial. You reconstitute it yourself with a suitable research solvent at the concentration your protocol requires.
Is the certificate of analysis specific to my vial?
Yes. The COA is matched to the production batch your vial came from, and covers HPLC purity and mass spectrometry identity performed by Janoshik, an independent testing lab.
Why third-party testing rather than in-house?
An external lab has no commercial interest in the outcome. For anyone who needs to justify reagent quality to a supervisor, a grant body or an internal QA process, independent analysis carries weight that a self-issued figure does not.
Should I order the single vial or the box of ten?
A single 20mg vial is suited to pilot work or a one-off assay. The box of ten is the better choice for extended studies, because running on material from one batch removes reagent variability as a confounding factor.
Where does it ship from?
From within Canada. Orders are shipped cold, packaged discreetly and tracked nationwide, so there is no international customs delay affecting transit time or storage conditions.
Can this be used on people or animals?
No. Cortagen is sold strictly as a laboratory research reagent for in-vitro use. It is not a drug, supplement, food or cosmetic and must not be administered to humans or animals.
In summary
Cortagen from Pure Peptides Canada is a lyophilized 20mg research reagent backed by independent HPLC and mass spectrometry testing and a batch-matched certificate of analysis, dispatched cold and tracked from within Canada. Choose the single vial for pilot work, or the box of ten to keep a study running on consistent material. For laboratory research use only.
