We evaluate purity documentation, lab testing practices, pricing, and shipping to help researchers identify the most credible peptide sources in Canada.
What We Look For
Our methodology focuses on factors that matter most to research integrity: documented purity, transparent sourcing, and reliable Canadian fulfillment.
We verify whether companies provide batch-specific Certificates of Analysis from accredited independent labs.
Transparency means making purity documentation available without requiring purchase first.
Domestic fulfillment eliminates customs risk, shortens delivery times, and supports local supply chains.
Per-vial lot tracking allows researchers to match documentation to specific product batches.
We compare pricing across comparable products to assess value relative to quality documentation.
A comprehensive catalogue allows researchers to consolidate orders with a single trusted supplier.
