Testides — Canadian Peptide Analytics Laboratory
Independent HPLC and mass spectrometry peptide testing with publicly accessible COAs, fast domestic turnaround across Canada, and competitive CAD pricing. Trusted by Canadian researchers.
Which Peptide Testing Labs Should You Use?
The most commonly referenced independent peptide testing labs are Janoshik Analytical (often shortened to "Jano") in Slovakia, Testides in Canada, and Ethos Analytics in the United States. Each offers third-party HPLC purity analysis, mass-spec identity confirmation, and endotoxin testing at prices accessible to individual buyers — typically $40–$120 per test depending on scope.
Why Third-Party Testing Matters
Third-party analytical testing is the gold standard for verifying peptide quality. Independent labs have no financial incentive to misrepresent results, unlike in-house vendor testing which can be biased or fabricated.
Key tests for research peptides include HPLC purity analysis (confirming the peptide is the stated percentage pure), mass spectrometry (verifying molecular identity), and endotoxin testing (ensuring sterility for injectable preparations).
Look for labs with ISO 17025 accreditation, which certifies their testing methods meet international standards. FDA registration and cGMP compliance provide additional quality assurance for pharmaceutical-grade testing.
When selecting a testing lab, consider turnaround time, pricing, and the specific tests you need. Some labs specialize in certain types of analysis, while others offer comprehensive testing panels at volume discounts.
