Lab results.

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

Scan the QR code printed on your vial label or on the box, which opens this library directly. You can also type the lot number or COA number into the search field on this page. Every lot has a permanent page at meritsciences.com/coa/[lot number] that requires no account and no request form.

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 lot.

Lots released on the current panel carry the complete signed PDF with the accredited laboratory named. On older lots, manufacturer and laboratory identifiers are redacted to protect supply-chain integrity. The measured data is never redacted — purity, identity, and lot number are reported exactly as measured.

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.
