Science
Verification is non-negotiable.
Products on our catalogue are verified in a Canadian lab before they ship. We publish the data so you can confirm what's in the vial before you order.
Our verification stack
Verified in Canada before a product lists.
Vetted manufacturing sources.
Every compound reaches a Canadian testing lab through a rigorous procurement process — we evaluate and vet multiple manufacturers, and reject those who do not meet our sourcing standards. This is the entry requirement — uncompromisable.
Third-party lab verification — done in-country, before shipping.
Every batch is independently tested at a Canadian laboratory before it lists. Verification happens in-country with full chain of custody — not sent overseas, where samples can spend weeks in transit and customs. The report we publish is from an independent Canadian lab, not the manufacturer or a third-party lab outside of Canada.
What every batch is tested for
Four assays. Each one definitive.
1 - HPLC purity.
High-performance liquid chromatography measures the percentage of the compound that is the target peptide versus impurities and synthesis byproducts.
2 - LC-MS identity.
Liquid chromatography–mass spectrometry confirms the molecular structure matches the claimed compound.
3 - LAL endotoxin.
Limulus Amebocyte Lysate assay quantifies bacterial endotoxin contamination — critical for any compound intended for parenteral research use.
4 - Sterility.
Microbial culture confirms no bacterial or fungal contamination.
Why lyophilized
The format that preserves the molecule.
Every compound we ship is lyophilized — freeze-dried and sealed in a vacuum or inert-gas vial. Lyophilization is the standard for research peptide stability. A lyophilized vial maintains structural integrity for 2–3 years unopened at room temperature.
By contrast, a reconstituted (liquid) peptide degrades meaningfully in 28–60 days even refrigerated.
This means no cold chain in transit, no degradation between supplier and you, and a longer usable window once the vial is in your hands.
Canadian operations
A Canadian company. Domestic dispatch.
PRL is a Canadian company. Products are independently verified and shipped from our Canadian facility. Once your order is dispatched there are no border crossings, no customs delays, and no cold-chain breaks in transit.
Orders ship within 48 hours of confirmation in tracked, unmarked packaging, anywhere in Canada.
