Check a batch
Match a batch number against its lab CoA
Batch numbers have no standard format — copy it exactly off the vial or the CoA. We search published Janoshik results, vendor-published CoAs, Finnrick lab data and community submissions. No match doesn't mean a product is fake: most batches have no CoA published anywhere. The PepAssure team also sends randomly selected samples to independent labs for further verification. Don't inject what you can't verify.
