Research peptides are legal to purchase and possess when properly labeled for laboratory research use. They are not approved by Health Canada for human therapeutic use, and a “research use only” label does not make human injection legal. The distinction Health Canada draws is about labeling and marketing — not the compound itself.
Public advisories on canada.ca named unauthorized injectable peptide sellers including a company called Canada Peptide, an advisory tied to a Calgary wellness centre, action against a seller called Prime Research, and a permanent injunction against a company called Canlab Research. Coverage from CBC News and Global News confirmed the injunction, and the College of Physicians and Surgeons of Alberta separately warned members about unauthorized injectable peptides reaching patients.
| Signal | Lower risk | Red flag |
|---|---|---|
| Lab testing | Independent third-party (e.g. Janoshik) | Seller's own in-house numbers only |
| Lot matching | COA lot number matches the vial received | Generic COA, no lot verification |
| Labeling | Explicit "research use only," no dosing-for-humans language | Marketed with human dosing/injection instructions |
| Claims | No therapeutic/medical claims | Promises of treatment, cure, or guaranteed results |
No. Growth Guys is not named in any of Health Canada's 2026 advisories. It publishes independent Janoshik lab results and labels products for research use — the same pattern this checklist describes as lower-risk. That's a fact worth verifying yourself rather than taking on faith: check the verification log and run the vendor-check quiz before buying from any source, including this one.
