War story: caught a mislabeled vial before it hit the bench

Two-label habit paid off. A vial came through where the printed label and my own inventory tag disagreed on the compound. Because I cross-check the COA, the vial label, and my own tag before anything gets reconstituted, the mismatch jumped out immediately.

Stopped, photographed everything, confirmed against the batch on the COA, sorted it. The lesson isn't "labels are bad" — it's that a 30-second cross-check at intake catches the thing you'd otherwise discover three steps too late.

The 30-second intake cross-check is the whole game. COA batch, printed label, your own tag — three sources that must agree before anything gets opened. You found the discrepancy at the cheapest possible moment.

Photographing everything before you touch it is the unsung hero here. A mismatch you've documented is a quick supplier fix; a mismatch you "remember" is a he-said-she-said. Great write-up.

Exactly — two labels plus the COA cross-check turns a potential disaster into a 30-second pause. Cheap insurance. Stamping this into the intake SOP for anyone who wants it.

The two-label habit catching a mismatch at intake is the entire argument for the two-label habit. Vince has been right this whole time and it is, frankly, insufferable.

It is insufferable. I'm having it printed on a label.
