Science
Verification is non-negotiable.
Products on our catalogue are verified in our 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 source.
Every compound reaches our Canadian lab through a rigorous global procurement process — we evaluate and vet multiple manufacturers, and reject many who do not meet our sourcing standards. This is the entry requirement — uncompromisable.
Canadian 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.
HPLC purity.
High-performance liquid chromatography measures the percentage of the compound that is the target peptide versus impurities and synthesis byproducts.
LC-MS identity.
Liquid chromatography–mass spectrometry confirms the molecular structure matches the claimed compound.
LAL endotoxin.
Limulus Amebocyte Lysate assay quantifies bacterial endotoxin contamination — critical for any compound intended for parenteral research use.
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.
