The supplier

The verify-first supplier we selected for Canadian buyers.

To keep the guide clean and educational, we keep our selected supplier on this single page. It's the one that matches what we teach: an independent Certificate of Analysis per batch, HPLC purity with LC-MS identity, and fulfilment that reaches Toronto without unnecessary border risk.

• Independent COA per lot — purity by HPLC, identity by LC-MS, tied to the exact batch.
• Sourcing that suits Canada — chosen to reduce CBSA border holds on the way to you.
• Verify anyway — always read the COA for your specific lot before you complete a purchase.
