Every lot, on the record
Purity you can’t verify is just a number on a label. Every lot we ship is lab-tested and comes with a Certificate of Analysis — the real figure for your vial, yours on request.
Purity, measured
Every lot is lab-tested and assigned a measured purity figure — the real number for that batch, not a label estimate.
On the COA
That figure is printed on the lot’s Certificate of Analysis, available on request for any product we carry.
Tracked by lot
Every vial carries a lot number tied to its COA and batch record — no mystery sourcing, no blended batches.
Held to 99%+
Our standard is 99%+ purity. The COA shows exactly where your lot landed — check it before you buy.
