Every Refine Research Labs lot is independently analyzed by accredited third-party laboratories in the United States. Certificates of Analysis (COAs) are published for every batch so you always know exactly what's in the vial.
Identity, purity, and net content are independently verified on every released lot.
Every lot is independently tested by accredited US laboratories before release.
Every lot ships with a downloadable Certificate of Analysis tied to its batch number.
Every Certificate of Analysis includes three independent test results so you can verify exactly what's in the vial.
Confirms the peptide matches its claimed sequence and molecular identity, so you know the product is what the label says it is.
Measures the concentration of the target peptide versus impurities, ensuring the lot meets our release specification before it ships.
Verifies the actual amount of peptide in the vial matches the labeled quantity, so dosing calculations start from an accurate baseline.
Reach out with your order or lot number and we'll send the matching certificate.
Choose a product, then select the lot on your vial to download its Certificate of Analysis.
What "Testing" covers and what to expect on every Certificate of Analysis.
Every released lot undergoes IPN testing at an accredited US laboratory: identity confirmation, purity analysis, and net content verification. When we say "tested," we mean independent third-party IPN testing on that specific batch.
Identity confirms the peptide matches its claimed sequence and molecular identity — so the product is what the label says it is.
Purity measures how much of the material is the target peptide versus impurities, expressed as a percentage of the active compound.
Net content verifies the actual amount of peptide in the vial matches the labeled quantity, giving you an accurate baseline for research calculations.
Testing is performed by BioViridian Inc., an independent, accredited laboratory based in the United States. Testing is completed on the finished lot — not on a reference sample from the manufacturer — so the COA reflects the material actually shipped.
Each vial is labeled with a lot number. The matching COA lists the same lot number at the top. If you can't locate it, send us your order or lot number and we'll forward the certificate.
Lots must pass all three IPN tests — identity, purity, and net content — before release. If a batch falls short on any test, it's rejected — not relabeled or sold at a lower grade.
