An independent Toronto laboratory, working with an accredited partner lab, dedicated to delivering fast, accurate, and defensible analytical data for research peptides and custom sequences.
Nexus Peptide Testing was founded in Toronto in 2023 to fill a critical gap: Canadian researchers needed fast, reliable, and truly independent analytical testing for research peptides without the delays and uncertainties of overseas labs.
Our founders — experienced analytical chemists with deep expertise in peptide characterization — built the lab from the ground up with one principle: every result must be defensible, reproducible, and delivered with full transparency.
Today we serve biotech startups, university labs, and pharmaceutical researchers across Canada with in-house HPLC, plus LC-MS/MS and impurity profiling through our accredited partner lab. We are 100% Canadian owned and operated, with same-day sample pickup available across the Greater Toronto Area.
Every report is reviewed by an analytical chemist with deep peptide chemistry knowledge before release.
Raw data, chromatograms, method details, and uncertainty estimates are included with every Certificate of Analysis.
We have no affiliation with any peptide vendor or manufacturer. Our only allegiance is to accurate data.
Same-day sample pickup available across the Greater Toronto Area. Secure shipping via Canada Post or courier welcome from anywhere in Canada.
