Weight Loss

The GLP-1 class is the most talked-about category in peptide research today, with retatrutide and tirzepatide leading interest among Canadian researchers studying metabolic and weight-regulation pathways. True North Peptides supplies these compounds — including semaglutide — at ≥99% purity, each with a third-party Certificate of Analysis so you know exactly what’s in every vial. We ship across Canada domestically — no international customs holds — with discreet packaging and tracking. Whether you’re comparing tirzepatide vs retatrutide in a head-to-head design or sourcing a single compound for a dose-response study, you’ll find research-grade material with verified purity here. Reconstitution and storage guidance is included on every product page. All compounds are for laboratory and research use only — not for human consumption.
