Batch checker
Paste the batch before you trust the vial.
The current static checker can verify known published batches and classify unknown codes without pretending to know more than the database contains.
Enter a batch code to check it against the current public Peptide Checker database.
If a batch is not in the database, that does not prove it is fake. It means Peptide Checker cannot verify it from the current public records.
