Every batch, tested.
You shouldn't have to take a seller's word for what's in the vial. Here's how we document production, and where to find the current reports.
What a Certificate of Analysis tells you
A Certificate of Analysis (COA) is a lab report tied to a specific production batch. For a product like this, it typically confirms the preservative concentration, sterility testing results, and the batch or lot identity. That means you can check what you're actually getting instead of relying on a marketing claim.
When you order, ask for the report that matches the lot number printed on your vial. If a batch isn't listed below, contact us directly.
