What is a lot number, and how is a lot different from a batch?

A lot number (or lot code) identifies the specific manufacturing and testing run a given unit belongs to. It is printed on the vial and matched, exactly, on that lot’s published record — if the two do not match, the material does not ship. “Batch” is often used interchangeably with “lot” in everyday conversation; where a distinction is drawn, a batch can refer to a manufacturing run before it has been finalized and assigned its lot identity through testing and release, while “lot” refers to that identified, released, traceable unit. On NuePharma’s records, the lot code is the identifier that matters.

Lot traceability — the ability to connect a specific vial to a specific, documented record — is what allows a purity result, a chromatogram, or a certificate to mean something specific rather than describing “the product” in general.

The milligram amount listed for a product (for example, 15 mg) denotes the labeled quantity of that compound in the vial, as stated on the product label and that lot’s own documentation — the exact figure and its basis are what the lot’s certificate and chromatogram report, not a number set independently of testing.
