How to verify BPC-157 is authentic
Step-by-step guide to verifying your BPC-157 is genuine: checking the COA, matching the batch number, and downloading from the product page.
Step 1: Locate the batch number
Every Peptify BPC-157 vial has a batch (lot) number printed on the label. Note this number down — it should match the Certificate of Analysis published on the product page for that specific batch.
Step 2: Download the COA from the product page
The batch-specific COA for your BPC-157 is downloadable directly from the product page on peptifyuk.com. This is the most reliable verification method because the document is hosted under our control, tied to the batch number, and includes the original HPLC chromatogram image plus mass spectrometry data.
If a supplier does not publish batch-specific COAs or only provides a generic purity claim, that is a significant red flag.
Step 3: Check the HPLC peak
On the COA, look at the HPLC chromatogram. A genuine BPC-157 sample should show a single dominant peak at the expected retention time, with purity >99% (peak area). The mass spectrometry section should confirm the molecular weight matches the theoretical mass of BPC-157.
Any chromatogram with multiple large peaks, or where the purity percentage looks inconsistent with the visible peak, should prompt you to contact the supplier for clarification.
