1. Match the batch
Find the batch or lot number on the certificate and on the vial. If they differ, the certificate is for different material.
2. Check the mass
The mass spectrometry section should report a measured mass close to the expected molecular weight for the named compound. For BPC-157 that is 1,419.5 g/mol. Reports often show charged ions, such as [M+H]+ at one unit higher, or [M+2H]2+ at roughly half.
3. Read the purity
HPLC purity is the main peak's share of everything the detector saw. A genuine report usually includes the chromatogram: a graph with one tall main peak and small impurity peaks.
4. Look for quantity
Purity is not quantity. A good certificate also states how many milligrams were measured in the vial, so you can compare it with the label.
5. Verify it
Use the lab's own website or verification code to confirm the report exists. Then watch for red flags:
