Why batch-level testing matters
Why each production batch gets its own lab report, and how to find the one for your vial.
Two vials of the same compound can come from different production runs. Batch-level testing means each run gets its own lab report, so you can check the results for the exact material you have.
What a batch is
A batch (or lot) is a specific quantity of material made in one production run and expected to be uniform within that run. ICH guidance on good manufacturing practice for active ingredients (ICH Q7) defines batches this way and expects each to be identified by a unique number.
Why one report per batch
Results can vary from one run to the next. A certificate of analysis from an earlier batch describes that batch, not a newer one. Testing each batch and publishing the report under its own number means:
- You can match the paperwork to the vial. The batch number on your label leads to the report for your material.
- Results stay traceable over time. Older batch reports stay online, so a vial bought months ago can still be checked.
- Records are easier to keep. You can file the exact report with your lab notes.
How it works at Genesis
- Each vial label carries its batch number.
- Each tested batch has its certificate of analysis published in the COA library, with HPLC purity and an endotoxin result.
- The product page shows the current batch, and earlier batches stay listed.
What batch testing doesn't do
Batch reports describe analytical results for that batch. They aren't statements about safety or effects, and Genesis products remain for laboratory research use only.
