COA Transparency
Review available certificates of analysis and supporting batch documentation for Precision Synthetics Canada products in one place.
Primary testing, with added Canadian verification
SideChain Analytics is our primary testing laboratory, with occasional supplementary testing by Testides, Vanguard Laboratory, and Janoshik.
Primary testing laboratory
SideChain Analytics (SCA) is our primary testing laboratory. Each batch COA shows the tests performed, results, and report verification details.
Occasional supplementary testing
Testides and Vanguard Laboratory provide occasional supplementary testing. The batch COA identifies the laboratory and the tests performed.
Additional testing and source records
We also use Janoshik for occasional supplementary testing. Existing Janoshik source-lab COAs remain available as supporting records for the batches they document.
The reports behind a rejected batch
We pay for the testing and absorb the cost of products that fail. See six reports from samples we kept off sale, and why we test every peptide batch.

Why some source-lab details are redacted
Precision Synthetics Canada redacts client, manufacturer, batch number, QR code, unique key, and other identifying details to protect source laboratories, suppliers, and their personnel from harassment or doxxing. The reported sample, test results, dates, and task number remain visible for review.
