Peptide Testing Labs

In this directory, a single-peptide analysis runs from CA$249 to CA$280 at the Canadian laboratories that publish a price, and from US$150 to US$450 in the United States and Europe. Endotoxin and heavy-metal add-ons are typically US$100 to US$300 each. Roughly half the laboratories listed quote per job rather than publishing a list.

Two to four days at the fastest laboratory here, three to five days at several, and five to ten business days at most. Compendial sterility to USP <71> takes 14 days by the culture method, which is why rapid PCR and ATP-bioluminescence alternatives exist.

Yes. There are Canadian laboratories in Ontario, Alberta and Quebec accepting domestic samples, several with published Canadian-dollar prices. Keeping the parcel inside Canada removes the customs step that makes cross-border testing slow and uncertain.

Identity answers what the compound is, usually by mass spectrometry. Purity answers how much of what was detected is that compound, usually as chromatographic area percent. Net peptide content answers how many milligrams of active peptide the vial actually holds. A vial can be 99% pure, correctly identified, and still badly underfilled, so a certificate carrying only one of the three leaves the other questions open.

ISO/IEC 17025 accreditation means a recognised body has assessed the laboratory against a published scope. It is stronger than the phrases "ISO 17025 aligned" and "ISO 17025 pending" that several laboratories here use, but it is scope-specific: confirm the method you need is on the accredited scope rather than assuming the badge covers everything the laboratory runs.

Usually one unopened vial, plus a second vial for any microbiology test, since sterility and endotoxin cannot share the vial used for purity. Most laboratories ask that testing details go on a slip of paper inside the package and that the exterior carry ordinary courier details only.
