Reading these results
- Identity (LC-MS) confirms the material’s molecular mass matches BPC-157.
- Assay is the measured amount per vial: 4.85 mg, 10.17 mg and 20.21 mg against 5, 10 and 20 mg labels.
- Purity (RP-HPLC) is the main peak as a percentage of all detected material. All three lots exceed the 98% specification.
- Endotoxin, sterility and (for the 5 mg lot) yeast & mold, residual solvents and heavy metals are standard laboratory quality screens reported by the testing lab.
Verifying a certificate
Each Optiq Health Labs certificate carries a sample ID and a QR code that links to the lab’s own verification page. Compare the sample ID (0327.OPT.260729, 0926.OPT.260820 or 0927.OPT.260820), lot number and results shown there with the certificate.
