Batch Numbers and Traceability

Why a batch number is the backbone of a study record

Two vials of the same product from different lots are not interchangeable reference materials. Results obtained on one lot should be traceable, in your notebooks and in any write-up, to that lot and to the analytical data recorded for it.

Structure of our lot numbers

Every P3P-research lot number follows one pattern:

P3P - <year><month> - <product code> - <sequence>

So P3P-2604-BPC-03 is the third lot of BPC-157 released in April 2026. The year and month are the date of release, not the date of synthesis.

Retrieving documentation

Open the Certificate of Analysis lookup and enter either the full lot number or the product name. The lookup returns the purity figure, the test method, the testing laboratory and the test date, with the batch certificate attached where one has been filed.

If you hold a lot number that returns nothing, it predates our current filing system or the certificate has not yet been uploaded. Contact us with the lot number and we will retrieve it for you.

Recording results against a lot

A workable minimum for any study record:

• Product name exactly as it appears on our product page
• Lot number as printed on the vial
• Certificate issue date
• The purity figure you are citing, together with the method

Store the certificate alongside the raw data rather than in a separate quality folder — the two are far more useful together.

Stability of the record

Batch certificates are retained indefinitely. If you are asked to supply supporting documentation for published work years after a study completes, the lot number on the vial is the only reliable way back to it. Write it down at the bench, every time.
