You can look up the printed batch number in Peptide Checker. A match shows a record in its current database. You still need to compare the label and lab report; a website lookup cannot test what is inside your vial.

An unlisted batch is unverified by the checker. That alone does not mean it is counterfeit. Ask the seller for the full report for that batch and a label photo that matches it.

COA means certificate of analysis. It records tests performed on a sample. Check the sample description, batch number, laboratory, date and methods. The report should make clear which results belong to that sample.

No. A purity result does not establish sterility, clinical safety or suitability for you. The TGA warns that unapproved peptide products have not been assessed for safety, quality and effectiveness. Speak with a qualified health professional about medical questions.

No. Peptide Doctor is an information site. It does not offer consultations or prescriptions. For symptoms, treatment choices or concerns about a product you have used, contact a qualified health professional.

The label alone does not establish that. The TGA says a research-use disclaimer does not make supply lawful. Rules depend on the product and the circumstances; check the current TGA guidance rather than relying on a seller's label.
