Certificate of Analysis, peptide lot record

A Certificate of Analysis (COA) is a laboratory document for one batch. It records the sample name, a method, and the results that method produced, commonly an area percent and a mass. It may also include an endotoxin line. It is not a Drug Identification Number, not a general specification for every future vial of that name, and not a Health Canada authorization.

On this site, published third-party files sit in the certificates library, grouped by product anchor. A report for a 10 mg vial does not document a 30 mg vial. A blend report does not document the single-peptide SKU. Start with what a peptide COA is, then how to read one.

One batch, one document

A Certificate of Analysis is a laboratory document for one batch. It records the sample name, a method, and the results that method produced. For a research peptide that is commonly an area percent and a mass. It may also include an endotoxin line. It is not a specification for every future vial of the same common name, and it is not a Drug Identification Number. A later batch needs its own file. A photograph of a report is not the report. Open the PDF and read the header before you read the percentage.

Match four strings before the vial enters a study file: sample name, date or task identifier, milligram fill, and, when the library prints it, cap colour. If those strings disagree with the glass in hand, the PDF does not document that glass. For the primer, see What is a peptide COA in Canada?. For the method note, see how to read a peptide COA. The index of files this catalogue has published is the certificates library.

Anchors that must not be swapped

The BPC-157 10 mg certificate covers the single-peptide 10 mg vial only. The GHK-Cu 50 mg certificate covers the copper complex, including its endotoxin link. Retatrutide 10 mg, 20 mg, and 30 mg each have a separate row. Tirzepatide does too. The 5 mg/5 mg BPC-157 and TB-500 blend documents that blend only. TB-500 10 mg has a separate purity report on the TB-500 10 mg certificate. The 10 mg/10 mg blend has its own row. A missing endotoxin line is a fact to write down. It is not a reason to reuse a neighbour's PDF, and this catalogue does not invent a missing file.

The fragment-versus-protein question for TB-500 is a sequence question, answered on What is TB-500?. A certificate, when one exists, is how you check the mass. Until that certificate exists, the research note cannot be used as a substitute spectrum. Price and stock stay on the shop URL. The catalogue is not the COA.

What the document does not change

A COA does not authorize human or veterinary use. Research-use-only wording plus a clean chromatogram is still not a Health Canada authorization. Read Are research peptides legal in Canada? and the Drug Identification Number entry if a purchasing form asks for an authorization identifier. The honest entry for these catalogue materials is that there is no DIN. Shipping remains Canada-only Xpresspost after Interac e-Transfer. Those facts are on the procurement guide, not inside the chromatogram.

BlueNex Labs hosts the library. The analytical laboratory named on the report is the testing laboratory. Those roles are different. A supplier page that displays a link is not the chromatogram. Founder context for who publishes the page is Alice Kay, Ph.D. How a row is added is on documentation standards. After the parcel arrives, the storage record is peptide storage for Canadian laboratories. Put the report URL on that record. Research use only.

If two fills share a shop path, they still need two documents when the library says so. File each URL next to its own milligram line. Do not merge them because the common name matches.
