Independent third-party verification

Lab results.

Every Merit batch is assayed by an independent laboratory before it is listed: purity by HPLC, identity against a reference standard. The certificate is published here before the batch ships, and every vial label and box carries a QR code that opens this library. No account, no request form.

How we verify

A full QC panel. Zero exceptions.

HPLC purity

High-performance liquid chromatography measures the exact purity of every batch before it is listed.

Identity confirmation

Each batch is confirmed against a reference standard: the compound is what the label says it is, with no substitutions.

Heavy metals + endotoxin

Elemental impurities by ICP-MS, plus endotoxin and sterility testing, screened to research-grade thresholds.

Fentanyl screen

Every batch on the current panel is screened for fentanyl by immunoassay, reported on the certificate itself.

A note on what’s shown. Batches released with a full certificate carry the complete PDF: accredited lab named, signed by the lab director, with an access code you can verify at the lab’s own portal. On older batches, manufacturer and laboratory identifiers are redacted to protect supply-chain integrity; the data never is. Purity, identity, and batch are reported exactly as measured.

Common questions

What the certificate does and doesn’t say.

Does Merit Sciences third-party test every batch?

Yes. Every batch is assayed by an independent laboratory before it is listed for sale, not sampled, not periodically, every batch. Purity is measured by HPLC and identity is confirmed against a reference standard. The resulting certificate is published on this page before the batch is listed.

How do I find the certificate of analysis for my batch?

Scan the QR code printed on your vial label or on the box, which opens this library directly. Search by compound to find the certificate for the batch currently shipping, or by the lab reference printed on your certificate. Every certificate has a permanent page that requires no account and no request form.

What does the purity percentage on a Merit COA mean?

It is the area percentage of the main peak in the HPLC chromatogram: the proportion of the material that is the stated compound, as measured by the testing laboratory. A result of 99.3% means the main peak accounted for 99.3% of the total peak area for that batch.

Why are some Merit certificates redacted?

Batches released on the current panel carry the complete signed PDF with the accredited laboratory named. On older batches, manufacturer and laboratory identifiers are redacted to protect supply-chain integrity. The measured data is never redacted: purity, identity, and batch identifier are reported exactly as measured.

Are Merit Sciences compounds FDA approved?

No. Merit compounds are sold for research use only and are not FDA approved, not for human or veterinary use, and not for diagnostic or therapeutic use. Independent lab verification is a statement about what is in the vial. It is not a statement about safety or efficacy, and it is not an approval of any kind.
