Every vial label has a QR code linking straight to that lot's CoA. If the code won't scan, type the lot number printed on the label below — it's the same number the testing lab references on the report itself.

Why we test every lot

Every product Jarp Bio sells is sold strictly for laboratory and research use — not for human or veterinary consumption. Each lot is tested by an independent third-party lab before it's listed. A Certificate of Analysis (CoA) is our record of those results.

We publish a CoA page for every lot we sell, whether the result is already back or still pending, and we keep our own stored copy of the lab's report.

Purity versus quantity: purity describes how much of what's in the vial is the actual compound, free of impurities or byproducts — it's a percentage. Quantity (e.g. the "5mg" on a label) is the labeled amount before reconstitution. The CoA reports what the lab measured for this specific lot; the label spec is what the product is formulated to.
