The first publicly queryable Certificate of Analysis database for compounded peptide medications.
A Certificate of Analysis (COA) is the document that proves what's actually in a compounded medication. It's issued per lot by an independent third-party laboratory after rigorous analytical testing.
For compounded peptide medications — BPC-157, semaglutide, tirzepatide, CJC-1295, and others — a COA is the only way to independently verify that the product matches its label claim.
Without one, you're taking someone's word for it.
Example COA card — illustrative only
When you inject a compounded peptide, you're trusting the pharmacy's quality process. A COA is the only independent verification that what's in the vial matches what's on the label. That proof should be public.
Every reputable US compounding pharmacy already produces COAs for every batch. This registry makes those documents publicly accessible for the first time — turning private quality data into public infrastructure.
Overseas suppliers and research chemical vendors cannot submit COAs to a US public registry. When a lot can't be verified here, that absence is information too. Silence speaks.
Enter the lot number printed on your medication label. We'll check it against the registry in real time.
Paste the lot number exactly as it appears on the vial or documentation.
Upload your first batch in under 10 minutes. No technical work required.
