How Liv Pure lots are tested, what the certificate of analysis measures, and where the limits of that documentation are.
✔ Independent Laboratories ✔ HPLC-UV Purity ✔ Lot-Specific Certificates
Every lot Liv Pure sells is sent to a third-party analytical laboratory before it is listed. Two laboratories currently perform this work: Vanguard Laboratory in Olympia, Washington, which is A2LA-accredited, and Nuvio Diagnostic LLC. The certificate you download is the laboratory’s own report for the sample it received. Liv Pure publishes it as issued and does not edit, summarize, or restate the results.
The certificates report chromatographic purity by HPLC with UV detection. The sample is dissolved, separated on a liquid-chromatography column, and monitored at a wavelength chosen for the compound, between 210 nm and 261 nm across the current catalog. The laboratory integrates every peak in the chromatogram, and the purity figure is the area of the main peak as a percentage of the total peak area. Each certificate shows the chromatogram itself, the peak table behind the percentage, the compound name and formula or sequence, the vial quantity, the identifiers assigned to the sample, and the date of analysis.
HPLC-UV purity describes the sample relative to other UV-absorbing species under the conditions of that run. It is not an identity test, and the current certificates do not include mass-spectrometric confirmation of molecular weight, amino-acid analysis, water content, counter-ion content, endotoxin, sterility, or microbial results. A laboratory that needs any of those parameters for its work should establish them on its own instruments before the material enters an assay. Liv Pure states this plainly so the certificate is read for what it is: a purity report for one analyzed sample.
Certificates carry the identifiers the laboratory printed on them. Most show a lot or batch number; all show the laboratory’s own sample ID and analysis date. The Certificates of Analysis page lists every current certificate with the lot exactly as it appears on the document. Match the lot printed on the vial label to that column. Where a certificate carries only a sample ID, or the lot on your vial is not listed, send the compound and lot number to support@livpurewellness.com and the certificate for that lot is returned by email.
Compounds ship as lyophilized powder in sealed glass vials with an aluminum crimp and flip-off cap. Keep vials sealed until they are needed. Store at 2–8 °C for short-term holding and at −20 °C for long-term storage, protected from light and moisture, and allow a vial to reach room temperature before opening so condensation does not form on the powder. Orders ship in insulated packaging by tracked carrier within the United States; see the Shipping Policy for transit details. Reference literature on each compound, restricted to in-vitro and preclinical studies, is collected in the Research Library, and the current catalog is organized by class under Research Compounds.
