> **Short answer:** Comparing Canadian peptide vendors comes down to three things you can actually verify — independent testing, domestic shipping, and a track record — not the marketing on the homepage.

## Testing is the only one that matters

Everything else is convenience. A vendor that shows independent, third-party results that verify on the lab's own portal, with the vendor named as the client, has cleared the bar most never reach.

## Shipping and recourse

Domestic shipping means no border uncertainty and a clearer path if an order goes wrong. It's a convenience difference, not a quality one.

## Track record and transparency

How long they've operated, whether they answer a direct testing question plainly, and whether their COAs match the batch you receive. Evasiveness is its own answer.
