How to Read a Peptide COA in the Philippines (Spot Fake Reports)

Buying research peptides in the Philippines? Sooner or later, someone sends you a COA. Here is how to read one. COA means certificate of analysis: a lab document recording test results on one specific batch or lot.

Start at the top: the lab. It should be independent and named, with its own website. Next, the sample. What was it submitted as, and who sent it in?

Then the batch or lot number. It ties the report to one production run, and should match the label on your vial. Check the dates: when the sample was received and analysed. Now the methods.

Identity is usually confirmed by mass spectrometry, which measures molecular mass. Purity is usually measured by HPLC, as a percentage. An endotoxin result, in endotoxin units, looks for bacterial contamination. Last, the verification key.

Janoshik, for example, lets anyone enter a task number and unique key on the lab's own site. Type that address yourself, not a link sent with the document. Three red flags. A COA made by the seller, not a lab.

A batch number that does not match your vial. And no way to verify it. Whether your order arrives same day in Metro Manila or by courier to Mindanao, check the vial against the report when it lands. If you are sourcing research peptides in the Philippines, Primara Labs publishes independent lab reports you can verify yourself.
